What must i do to check my cpp program

Question

I'm still a newb for these kind of things, so i need to know how the way to check my program (c++) is it ok or error... can anyone tell me how ?

Answer 1

You're using the wrong operator for cin:
change:
cin << x << y;
to:
cin >> x >> y;

After this fix your code works fine.

Answer 2

press run at code playground

Answer 3

I have tried your program twice. I got a compilation error. You can try by pushing the run button.

Answer 4

Try this line for cin: cin >> x >> y;

Answer 5
