  • Question
  • What will be the output of the program?
    #include<stdio.h>
    
    int main()
    {
        int i;
        i = scanf("%d %d", &i, &i);
        printf("%d\n", i);
        return 0;
    }
    


  • Options
  • A. 1
  • B. 2
  • C. Garbage value
  • D. Error: cannot assign scanf to variable

  • Correct Answer


  • Explanation
    scanf() returns the number of variables to which you are provding the input. i = scanf("%d %d", &i, &i); Here Scanf() returns 2. So i = 2.

    printf("%d\n", i); Here it prints 2.
