Question

I like (bool) way more, but it generates warnings. How do i get rid off the warnings?

I have code like:

bool something_else = 0;

void switcher(int val = -1){
    if(val != -1){
        something_else = (bool)val;
    }else{
        something_else ^= 1;
    }
}

Should i just do it like everyone else and use ‘!!’ or make it somehow hide the warning messages when using (bool) ? Or is ‘!!’ actually faster than (bool) ?

I would like to use (bool) and so i have to hide the warning, but how?

Edit: Visual Studio 2008 i am using, sorry i forgot to tell.

Edit 2: The warning message is warning C4800: 'int' : forcing value to bool 'true' or 'false' (performance warning) And it comes on the line something_else = (bool)val; And on the line something_else = val; But not on the line something_else = !!val;

The problem is, i want it to respect that i want to convert it to boolean. I dont want to hide all boolean warnings, because sometimes they saved my ass.

Answer 1

another way:

switch (val) {
  case -1: something_else = !something_else; break;
  case  0: something_else = false; break;
  default: something_else = true; break;
}
