What will be the output of the following code snippet?
 

Y = 5;
if (! Y > 10)
X = Y + 3;
else
X = Y + 10;

printf(" X = %d Y = %d", X, Y);

 

  • A.The program will print X = 15 Y = 5
  • B.The program will print X = 15 Y = 0
  • C.The program will print X = 8 Y = 5
  • D.The program will print X = 3 Y = 0

Answer: A

Correct answer: The program will print X = 15 Y = 5

! binds far tighter than >, so the condition is (!Y) > 10, not !(Y > 10). With Y equal to 5, !Y is 0, and \(0 > 10\) is false. The else branch runs, giving \(X = 5 + 10 = 15\), and Y is never modified, so the output is X = 15 Y = 5.
