Which bitwise operator is suitable for turning off a particular bit in a number?

  • A&& operator
  • B& operator
  • C || operator
  • D! operator

What is the output of this C code? 

#include<stdio.h>
int main()
{
	int i = 7;
	i = i / 4;
	printf("%d\n", i);
	return 0;
}

  • ARun time error
  • B1
  • C2
  • D3

What is the output of the following Program?

  • A11
  • B14
  • C12
  • D13

What will be the output of the program? 

#include<stdio.h>

int main()
{
    int i=4, j=8;
    printf("%d, %d, %d\n", i|j&j|i, i|j&&j|i, i^j);
    return 0;
}

  • A4, 8, 0
  • B1, 2, 1
  • C12, 1, 12
  • D0, 0, 0

Choose the correct output for the following program. 

#include<stdio.h> 
void main()
 {
  1 < 2 ? return 1: return 2;
 }

  • Areturns 1
  • Bvaries
  • C returns 2
  • DCompile time error

Which of the following statements are correct about the program? 

#include<stdio.h>

int main()
{
    unsigned int num;
    int c=0;
    scanf("%u", &num);
    for(;num;num>>=1)
    {
        if(num & 1)
            c++;
    }
    printf("%d", c);
    return 0;
}

  • AIt counts the number of bits that are ON (1) in the number num.
  • BIt counts the number of bits that are OFF (0) in the number num.
  • CIt sets all bits in the number num to 1
  • DError

What is the output of this C code? 
    int main()

            printf("no\n");
    }

  • AYes
  • B No
  • CCompile time error
  • DUndefined

What is the output of this C code? 
    void main()
    {
        int x = 1, y = 0, z = 5;
        int a = x && y || z++;
        printf("%d", z);
    }

  • A6
  • B5
  • DVaries

What will the output of the follwing code? 

#include <stdio.h>
// Assume base address of "ABCDEQuiz" to be 1000

   return 0;
}

  • AABCDEQuiz
  • BQuiz
  • C10005
  • DCompile time error
