Flow Control - Programming

Q1:

What will be the output of the program? 
int x = l, y = 6; 
while (y--) 
{
    x++; 
} 
System.out.println('x = ' + x +' y = ' + y);

A x = 6 y = 0

B x = 7 y = 0

C x = 6 y = -1

D Compilation fails.

ANS:A - x = 6 y = 0

Compilation fails because the while loop demands a boolean argument for it's looping condition, but in the code, it's given an int argument. while(true) { //insert code here }
