Find the Output: Postfix and prefix increments

31Find the output of the following C code (assume #include and that the code is inside int main(void)):
int x = 3;

if (x++ > 3)
    printf("A");
else if (++x > 4)
    printf("B");
else
    printf("C");

printf("%d", x);
  • Option : B
  • Explanation : x++ compares the old value 3 with 3, which is false, then makes x equal to 4. ++x next makes x equal to 5 before comparing; 5 > 4 is true, so B5 is printed.
