Thread: overloading question

Maybe it's not overloading... I don't know what it is.

Basically:

Code:

int main() {
  int random;
  if (random > 3)
    int value;
  if (random <= 3)
    float value;

  add_factor(value);






}
void add_factor(int temp) {

}
void add_factor(float temp) {


}

Is this code illegal? Under what circumstances could value be used without error? (Pretend that these variables have values of some importance in them, and that add_factor(int) is different than add_factor(float).

Its not legal. You are declaring "value" twice in their own statement blocks and don't have scope within main(). For example, the following is equivalent:

Code:

int main() 
{
   int random;
   if (random > 3)
   {
      int value; //can't access value outside of {}
   }
   if (random <= 3)
   {
      float value;
   }

  add_factor(value); //value not defined in this scope

  return 0; //added for correctness
}

Your function declarations for add_factor() are ok. The type of the parameter will determine which function is called.

You can accomplish what [it looks like] you were thinking like this:

Code:

   if (random > 3)
      add_factor(<something of int type>);
   if (random <= 3)
      add_factor(<something of float type>);

You can use templates and template specialization to do something similiar.

I see. Thanks.
