MCQs with Solutions
Here are the correct answers for the Multiple Choice Questions (MCQs) in Chapter 2:
- A) Input/Output Operation
- D) Both A & B
- D) getch()
- A) printf()
- A) scanf()
Short Questions and Answers
Q1: What is the printf()
function?
Answer:printf()
is a built-in function in the C programming language used to display formatted output on the screen. Syntax:
printf("control string", list of arguments);
Q2: Define format specifiers in C.
Answer:
Format specifiers define the type of data to be printed or inputted. Examples: %d
for integers, %f
for float, %c
for character.
Q3: What are escape sequences?
Answer:
Escape sequences are special characters in C used to control output. For example:
\n
creates a new line\t
adds a horizontal tab
Long Questions with Solutions
Q1: Explain the scanf()
function with an example.
Answer:scanf()
is a function used to take input from the user into variables. Syntax:
scanf("control string", list of variables);
Example:
#include<stdio.h>
void main() {
int age;
printf("Enter your age: ");
scanf("%d", &age);
printf("Your age is: %d", age);
}
Q2: Describe arithmetic operators with an example.
Answer:
Arithmetic operators are used for basic mathematical operations. Example:
Operator | Description |
---|---|
+ | Addition |
- | Subtraction |
* | Multiplication |
/ | Division |
% | Modulus |
Program Example:
#include<stdio.h>
void main() {
int a = 10, b = 5;
printf("Sum = %d", a + b);
printf("Product = %d", a * b);
}
