Question

Guys, I am not exactly sure what happens here for the if statement. I did a bunch of google searches, but nothing comes up. Obviously, the function x() returns something. Either a 1 or a 0. But I am not sure what it does. Is it short hand for x() == 0 or x() == 1. I am just going over coding examples and I noticed it.

Answer 1

if(!x())
{
   // executes if x() is 0
   // x() == 0
}

 

if(x())
{
   // executes if x() is non-0
   // x() != 0
}
