  • Question
  • What will be the output of the program?
    #include<stdio.h>
    int main()
    {
        int x=55;
        printf("%d, %d, %d\n", x<=55, x=40, x>=10);
        return 0;
    }
    


  • Options
  • A. 1, 40, 1
  • B. 1, 55, 1
  • C. 1, 55, 0
  • D. 1, 1, 1

  • Correct Answer
  • 1, 40, 1 

    Explanation
    Step 1: int x=55; here variable x is declared as an integer type and initialized to '55'.
    Step 2: printf("%d, %d, %d\n", x<=55, x=40, x>=10);
    In printf the execution of expressions is from Right to Left.
    here x>=10 returns TRUE hence it prints '1'.
    x=40 here x is assigned to 40 Hence it prints '40'.
    x<=55 returns TRUE. hence it prints '1'.
    Step 3: Hence the output is "1, 40, 1".
