The output of the following statement is: printf("%d", 5+2);
- 7
- 5+2
- error
- %d7
Show answer and explanation
Answer: A. 7
5+2 evaluates to 7 and %d formats it as an integer, so the output is 7.
Which function is used for input handling in C?
- scanf()
- printf()
- cin>>
- system()
Show answer and explanation
Answer: A. scanf()
scanf() is the standard C library function used to read input from the keyboard.
The output of the following statement is: printf("%d", 5+2);
- 7
- 5+2
- error
- %d7
Show answer and explanation
Answer: A. 7
5+2 evaluates to 7, and %d prints it as an integer, so the output is 7.
Which function is used for input handling in C?
- scanf()
- printf()

________ is a software that loads a program into memory and then executes it.
- Linker
- Loader
- Compiler
- Debugger
Show answer and explanation
Answer: B. Loader
A loader copies an executable program from storage into main memory and starts its execution; a linker combines object modules, a compiler translates source code.
Give the significance of #include in C programming.
Show model answer
#include<stdio.h> is a preprocessor directive that tells the compiler to include the Standard Input Output header file, which contains the declarations of standard I/O functions such as printf() and scanf(). Without it, using these functions would cause compile errors.
Correct any four errors in the given code:
1 void main();
2 {
3 int marks
4 printf("Enter marks");
5 scanf("%d", marks);
6 if (m<32);
7 printf("Pass");
8 }
Show model answer
(1) Line 1: void main(); has an extra semicolon — should be void main().
(2) Line 3: int marks is missing a semicolon — should be int marks;.
(3) Line 5: scanf("%d", marks); is missing the address-of operator — should be scanf("%d", &marks);.
(4) Line 6: if (m<32); uses an undeclared variable m (should be marks) and has a stray semicolon that makes the if do nothing — should be if (marks<32) (no semicolon) so line 7 belongs to it.
