What happens when you logical not a float?

Question

I assume this just returns an int. Is there anything else going on I should be aware of? C/C++ differences?

float a = 2.5;
!a; // What does this return? Int?         


        

Answer 1

See for yourself:

#include 

int main()
{
   float a = 2.5;

   if ( !a )
       std::cout << !a << "\n";

   else
       std::cout << !a << "\n";
}
