12th Class Computer Science Chapter 9 Short Questions with Answers Online Preparation

Question # 1

Trace the output in the following code.
Int x =10 y =15;
X=x++;
Y= ++y;
Prontf ("%d%d",x,y);

Ans 1: Output: x= 11
y=16

Question # 2

What is assignment operator ?

Ans 1: The Assignment operator is used to store a value or a computational result in a variable . In C, the symbol= represents the assignment operator e.g. In the following statement, values of the two variables, height and width, are multiplied and the results is assigned to the variable Area
Area = Height*width
The value of the right side of the operator is assigned to the variable on the left side of the assignment operator .

Question # 3

Define Data Type.

Ans 1: In C, the data type defines a set of values and aset of operations on those values. We know that computer program manipulates various types of data. In a C program we may need to process different types of data . Therefore variables should be capable of storing data of different types.This is done by associating certain data types to the variables.There are two different types of data.
- Standard Data Types
- User-define Data Types

Question # 4

Trace the output.
Int number = 6;
Int x= 0;
X =-- number ;
Printf ("%d",x);

Ans 1: Output: x=5

Question # 5

List any four types of integer data in C-Language.

Ans 1: There are the following types of integer data in C-Language:
- Int
- Short
- Long
- Long long

Question # 6

Differentiate between Unary and binary operator.

Ans 1: Unary Operator: Unary mean consisting of single component or element. Operator means a symbol that tells the compiler to perform specific mathematical or logical functions. A unary operator in C is an operator that takes a single operand in an expression or statement.
Ans 2: Binary Operator: A binary operator is an operator that operates on two operands and manipulates them to return a result.Operators are represented by special characters or by keywords and provide an easy way to compare numerical values or character strings

Question # 7

What is the value of y after the following code executes?

Ans 1: Float y = 3.4 +sqrt (25.0)
Value of Y : Y= 8.4

Question # 8

Differentiate between function definition and declaration .

Ans 1: Function Definition : A function is a group of statements that together perform a task . A function definition provides that actual body of the function . The C standard library provides numerous built-in functions that your program can call .
Ans 2: Declaration : The term deceleration means (in C) that you are telling the compiler about type: size and in case of function declaration type the size of its parameters of any variable, or user defined type or function in your program. No space is reserved in memory for any variable in case of declaration.

Question # 9

Differentiate between increment and decrement operators.

Ans 1: Increment Operators: The increment operator increase the value of its operand by one. It is denoted by the symbole ++.
Example: Count++, Where count is a variable. The effect of this expression is equivalent to the following expression:
Count =
Count +1;
Ans 2: Decrement Operators: The decrement operator decreases the value of its operand by one. It is denoted by the symbol--.
Example count--, where count is a variable . The effect of this expression is equivalent to the following expression:
Count =
Count -1;

Question # 10

Find the Errors in the following code.

Ans 1: #include<sttd10.h>
Void main (void)
{
int x, y, z
z= x+y+z
}
Errors: There are the following errors in this program:
1. 1st error is in this program is that the library has been used is wrong because std10.h has been used instead of stdio.h.
2. 2nd error is in this program is that no terminator has been used in both statements.
