  • Question
  • What will be the output of the program?
    #include<stdio.h>
    int func1(int);
    
    int main()
    {
        int k=35;
        k = func1(k=func1(k=func1(k)));
        printf("k=%d\n", k);
        return 0;
    }
    int func1(int k)
    {
        k++;
        return k;
    }
    


  • Options
  • A. k=35
  • B. k=36
  • C. k=37
  • D. k=38

  • Correct Answer
  • k=38 

    Explanation
    Step 1: int k=35; The variable k is declared as an integer type and initialized to 35.

    Step 2: k = func1(k=func1(k=func1(k))); The func1(k) increement the value of k by 1 and return it. Here the func1(k) is called 3 times. Hence it increements value of k = 35 to 38. The result is stored in the variable k = 38.

    Step 3: printf("k=%d\n", k); It prints the value of variable k "38".
