  • Question
  • What is the output of the program given below?
    #include<stdio.h>
    int main()
    {
        enum status { pass, fail, atkt};
        enum status stud1, stud2, stud3;
        stud1 = pass;
        stud2 = atkt;
        stud3 = fail;
        printf("%d, %d, %d\n", stud1, stud2, stud3);
        return 0;
    }
    


  • Options
  • A. 0, 1, 2
  • B. 1, 2, 3
  • C. 0, 2, 1
  • D. 1, 3, 2

  • Correct Answer
  • 0, 2, 1 

    Explanation
    enum takes the format like {0,1,2..) so pass=0, fail=1, atkt=2

    stud1 = pass (value is 0)

    stud2 = atkt (value is 2)

    stud3 = fail (value is 1)

    Hence it prints 0, 2, 1
