Find the Output: Boundary condition in ladder

47Find the output of the following C code (assume #include and that the code is inside int main(void)):
int x = 20;

if (x > 20)
    printf("A");
else if (x >= 20)
    printf("B");
else if (x == 20)
    printf("C");
else
    printf("D");
  • Option : B
  • Explanation : x > 20 is false, while x >= 20 is true. The ladder prints B without testing the later x == 20 branch.
