What are the values of the variables s and x after running this piece of code?

Question

int s = 12;
int x = 87;
do
{
s = x;
x -= 40;
}while (x < 20);

Answer 1

first loop:
s = 87, x = 47.
Second loop cannot be executed because x is greather than 20.

do-while loop executes at least one loop, what cannot be done with while loop.

Answer 2

try it by yourself, by running it in a code playground ;P
