1. Declaration statement. Variables are identifiers of memory locations add are used in programs to refer to data. They should be declared prior to their use in the program and data types are required for this. The syntax of variable declaration is:

data type <variable1>
[, <variable2>, <variable3 >,...];
eg., int rollno, age;

2. Assignment statement. A specific data is stored in memory locations (variables) using an assignment operator (=). The statement that contains = is known as assign.. ment statement. It is also a binary operator and the operand to the left of = should be a variable. The operand after = may be a numeric constant, a variable or an expression of numeric type.

Answer 12.
In implicit type conversion, compiler is responsible for the conversion. It always converts a lower type into, higher one and hence it is also known as type promotion,
eg., For example, the expression 5 / 2 * 3 + 2.5 which gives the result 8.5. The evaluation steps are as follows:
Step 1: 5/2 gives 2 (Integer division) Step 2: 2 * 3 gives 6 (Integer multiplication)
Step 3: 6 + 2.5 gives 8.5 (Boating point addition, 6 is converted into 6.0)

1. Syntax errors result when the rules or syntax of the programming language are not followed. Such program errors typically involve incorrect punctuation, incorrect word sequence, undefined term, or illegal use of terms or constructs. In the case of interpreters, the syntax errors will be detected and displayed during execution,

2. The logical error is due to the improper planning of the program’s logic. The language processor successfully translates the source code into machine code if there are no syntax errors. The computer actually follows the program instructions and gives the output as per the instructions. But the output may not be correct. This is known as logical errors. In order to determine whether or not there is a logical error, the program must be tested.

Answer 21.
Base address (Lvalue) 3000

Answer 22.
a. Preprocessor directives. A C++ program starts with preprocessor directives. Preprocessors are the compiler directive
‘ statements which give instruction to the compiler to process the information provided before actual compilation starts. The # include is used to link the header files available in the C++ library. There are some other preprocessor directives such as # define, # undef, etc.

b. Header files. It contains the information about functions, objects and predefined derived data types and they are available along with compiler. The header file ios team contains the information about the objects cin and cout.

c. The main() function. The execution starts at main() and ends within main(). If we use any other function in the program, it is called (or invoked) from main(). The function header main() is followed by its body, which is a set of one or more statements within a pair of braces {}. This structure is known as the definition of the main() function. Each statement is delimited by a semicolon (;).

Answer 23.
C++ provides data type modifiers which help us to alter the size, range or precision. It alters the range of values permitted to a data type by altering the memory size and/or sign of values. Important modifiers are signed, unsigned, long and short.

Answer 24.

# include <iostream> 
using namespace std; 
int main()
{
int a;
cout<<“Enter an integer:”; 
cin >> a;
if (a > 0) .
cout<<“The number is positive”;
else if (a < 0) *
cout<<“The number is negative”;
else
cout<<“The number is zero”; return 0;
}

Answer 29.
a. A looping statement has four components: initialization expression, test expression, update expression, loop body. The loop body is the set of statements for repeated execution. The execution is continued as long as the test expression (condition) is true. The variable used in the test expression, called a loop control variable, gets its initial value through the initialization expression (or statement). Update expression changes the value of the loop control variable. Usually, it takes place after each execution of the loop body.

b. while loop. The condition is checked first and if it is found, True the body of the loop will be executed. That is the body will be executed as long as the condition is True. The syntax of a while loop is, initialization of loop control variable;

while (test expression)
{
body of the loop;
updation of Ipop control variable;
}
eg., int k= 1; while(k<=3)
{
cout << k << `\t’;
++k;
}

do while loop. The condition is checked only after executing the loop body. So it is certain that the loop body will be executed at least once in the case of do while loop.

Syntax is:
initialization of loop control variable; 
do
body of the loop;
updation of loop control variable;
}
while (test expression); 
eg., int k = 1; do {
cout << k << At’;
++k;
}
while (k<=3);

Answer 30.
a. The physical or logical arrangement of computers on a network is called structure or topology. It is the geometrical arrangement of computers in a network,
b.
1. Ring topology. All the computers are connected in the shape of a ring and it is a closed-loop. Here also there is no central computer. Here a computer transmits a message, which is tagged along with its destination computer’s Address. The message travels in one direction and each node checks whether the message is for them. If not, it passes to the next node. It requires only short cable length. Its advantages are no signal amplification required because each node do this and requires less cable, so cost-effective. The main disadvantage is if a node fails, the entire network will fail.

2. Bus topology. All the computers are attached to a single cable, called the bus. If anyone node has to send data to another node, it will send the data to the bus. In the bus, the data travels in both directions. The node that needs the data copies it. A small device called terminator connected at both end of the bus removes the data and frees the bus for next transmission. Advantages are added or remove computer is very easy. It requires less cable length and the installation cost is less. A disadvantage is fault detection is very difficult because of no central computer,

c. Hub. It is a small, simple and inexpensive device used to connect computers (devices) to a network. If a computer wants to transmit data to another computer, first it sends to the hub, the hub retransmits this data to all other computers. Each and every computer gets the data and check whether it is for them or not. It increases the network traffic and hence the transmission speed is low.

Switch. It is an expensive device used to connect computers (device) to a network. Unlike a hub, switch transmit data, not to all computers, it retransmits data only to the intended computer. So the traffic is less and the speed is high.

b. M is upper case in main(), no semicolon used in any statements. Operators of sin and cout are wrong. Missing in conditional operator?

Answer 11.
A simple arithmetic statement can be expressed in a more condensed form using arithmetic assignment operators.
eg., a=a+10 can be represented as a+=10. Here += is arithmetic assign* meant operator. The arithmetic assignment operators in C++ are +=, =,*=,/=, %=. These are also known as C++ shorthands. These are all binary operators and the first operand should be a variable. The use of these operators makes the two operations (arithmetic and assignment) faster than the usual method.

A computer can solve problems only when we give instructions to it. If it understands the tasks contained in the instructions, it will work accordingly. An instruction is an action-oriented statement. It tells the computer what operation it should perform. A computer can execute (carry out the task contained in) an instruction only if the task is specified precisely and accurately.

Answer 19.
A sequence of instructions written in a language that is understood by a computer is called a computer program.
The algorithm is a step by step procedure to solve a problem. Each step represents a specific task. These steps help the programmer to write instructions in a programming language.

Answer 20.
Identifiers are the user-defined words that are used to name different program elements such as memory locations, statements, functions, objects, classes etc.

The words (tokens) that convey a specific meaning to the language compiler are called keywords. These are also known as reserved words as they are reserved by the language for special purposes and cannot be redefined for any other purposes.

The advantages of networks are:

1. Resource sharing: All the computers in a network can share software.
2. Reliability: If one computer fails, the other computer can perform the work without any delay.
3. Price Vs Performance: Instead of a main frame 10 personal computers are used with less cost and same performance.
4. Communication medium: It has a powerful communication medium. We can exchange information between computers in a network.
5. Scalable: System performance can be increased by adding computers to a network.

Answer 14.
Transmission Control Protocol (TCP) uses a set of rules to exchange\messages with other internet points at time information packet level. When data is to be sent from one computer to another over the internet, it is first broken into smaller packets by TCP and then sends. When these packets are received by the receiving computer, TCP submits a request for retransmission else packets are assembled into the original message according to the rules specified in the TCP protocol. Delivery of each packet to the right destination is done by Internet Protocol (IP).

Answer 18.

Answer 19.
It is the stage where programming errors are discovered and corrected, programming errors are known as ‘bugs’and the process of detecting and correcting these errors is called debugging.

The error messages may be displayed by the error-handling function of the language. These errors are known as a runtime error. These errors can be rectified by providing instruction for checking the validity of the data before it gets processed by the subsequent instructions in the program.

The logical error is due to the improper planning of the program’s logic. The language processor successfully translates the source code into machine code if there are no syntax errors. The computer actually follows the program instructions and gives the output as per the instructions. But the output may not be correct. This is known as logical errors.

The error messages may be displayed by the error-handling function of the language. These errors are known as a runtime error. These errors can be rectified by providing instruction for checking the validity of the data before it gets processed by the subsequent instructions in the program.

Answer 20.
a. Tokens or lexical units are the fundamental building blocks of the program. C++ has five types of tokens. They are keywords, identifiers, literals, punctuators, and operators.
b. Identifiers are the user-defined words that are used to name different program elements such as memory locations, statements, functions, objects, classes etc.
The words (tokens) that convey a specific meaning to the language compiler are called keywords. These are also known as reserved words as they are reserved by the language for special purposes and cannot be redefined for any other purposes.

Answer 21.
a. The data type specifies the nature of
data we have to store, the set of operations that can be performed on the data. Predefined data types in C++ are char, int, float, double and void, b. int data types; Integers are whole numbers without a fractional part: They can be positive, zero or negative. The keyword int represents integer numbers. It allows 4 bytes of memory.

char data types. All letters, digits, special symbols, punctuations, etc. come under this category. When these characters are used as data they are considered as char type data in C+ +. The keyword char represents character type data, void data type. The data type void is a keyword and it indicates an empty set of data. It does not require any memory space, float data types.

Numbers with a fractional part are called floating point numbers. The keyword float is used to denote such numbers. It allows 4 bytes of memory, double data type. It is used to store large real numbers. It uses 8 bytes of memory. It can be represented as double.

Answer 22.
Arithmetic operators: These are defined to perform basic arithmetic operations such as addition, subtraction, multiplication, and division. The symbols used for this are +,* and / respectively. It provides a special operator, % (modulus operator) for getting remainder during division.
Logical operators: Used to combine relational operations and it gives either true or false.

Answer 23.
a. i. x = x % 20;
ii. a = a + 2;
iii. p = p/5;
b. A specific data is stored in memory lo-cations (variables) using assignment op-erator (=). Here the value 20 is stored in the variable
a. == (equal to) is a relational operator used for comparing numeric data. Here the value 20 is compared with the value stored in the variable a.

Answer 28.
a. Software is a general term used to denote a set of programs that help us to use a computer system and other electronic devices efficiently and effectively. The two types of softwares are:
1. System software: It is a set of one or more programs designed to control the operations of a computer.

• Operating system: It is a set of programs that acts as an interface between the user and computer hard ware.
• Language processors: The instructions to the computer are written in different languages. Various language processors are:

a. Assembler: It converts languages written in assembly language into machine language.
b. Interpreter: It converts a high-level language into machine language by-line by line.
c. Compiler: It translate a high level language into machine language by converting all the lines at a time.

• Utility software: A set of programs which help users in system maintenance tasks and in performing tasks of routine nature. Utility programs are compression tools (WinZip, Win RAR), disk defragmenter (rearranges files on a computer hard disk), backup software.

2. Application software: It is tHe software developed for a specific application. It ineludes general purpose software\(Word Processing software, spreadsheet sbftware, presentation software, database, multimedia), specific purpose software (designed to handle particular tasks).
b. Compiler: It translate a high level lan-guage into machine language by converting all the lines at a time. The errors are provided at the end of the compilation. The programming language that have a compiler are C, C++, Pascal, etc.

Interpreter: It converts a high level language into machine language by line by line. If there is an error in one line, it reports and the execution is terminated. It will continue the translation only after the correction of the error, eg., BASIC is an inter-preted language.
c. It gives the user the freedom to use, copy, distribute, examine, change and improve the software.

Answer 29.
a. Type conversion is the process of con-verting the current data type of a value into another type. It may be implicitly and explicitly converted.
It can be done in two ways:
1. Implicit type conversion: It is performed by C++ compiler internally. In expressions where different types of data are involved, C++ converts the lower sized operands to the data type of the highest sized operand. Since the conversion is always from lower type to higher, it is also known as type promotion.

2. Explicit type conversion: Sometimes the programmer may decide the data type of the result of an evaluation. This is done by the programmer by specifying the data type within parentheses to the left of the operand. Since the programmer explicitly casts a data to the desired type, it is also known as type casting. Usually, type casting is applied on the variables in the expressions.
b. Sometimes the programmer may decide the data type of the result of an evaluation.

This is done by the programmer by sSpecitying the data type within parentheses to the left of the operand. Since the programmer explicitly casts a data to the desired type, it is also known as type casting.
c. a = 3.0 or 3
b = 2.5

Answer 30.
a. Physical or logical arrangement of computers on a network is called structure or topology.
b. Bus topology. All the computers are at-tached to a single cable called the bus. Here one computer transmits all other computers listen. Therefore it is called the broadcast bus. The transmission from any station will travel in both the direction. The connected computers can hear the message and check whether it is for them or not. Advantages are add or remows computer is very easy. It requires less cable length and the installation cost is less,
c. Local Are Network (LAN): This is used to connect computers in a single room or buildings of one location by using twisted pair wire or coaxial cable. Data transfer rate is high and an error rate is less.

Wide Area Network (WAN): This is used to connect computers over a large geographical area. It is a network of networks. Here the computers are connected using telephone lines or Microwave station or satellites. The error rate in rate in data transmission is high, eg., internet.

1. The size of items or mid-points of classes is cumulated. The cumulative sum of the items is assumed to be 100. All the different cumulative totals are converted into a percentage.

2. Frequencies are also made cumulative. Last cumulative frequency is considered as 100. Other frequencies except the last are converted into a percentage.

3. Cumulative frequencies are plotted on X-axis while cumulative items are plot­ted on the Y-axis.

4. We start on X-axis while cumulative items are plotted on the Y-axis

5. 0 on X-axis and 100 on Y-axis are joined by a line. This line is known as the line of equal distribution.

6. We plot the values on X and Y axis in an ordinary way and the plotted points are joined by a curve. It is the curve of ac­tual distribution.

7. The lesser distance between the line of equal distribution and line of actual distribu­tion shows lesser dispersion and so on.
