You can overload the function call operator ()
:
Overloading must be done inside of a class
/struct
:
//R -> Return type
//Types -> any different type
R operator()(Type name, Type2 name2, ...)
{
//Do something
//return something
}
//Use it like this (R is return type, a and b are variables)
R foo = object(a, b, ...);
For example:
struct Sum
{
int operator()(int a, int b)
{
return a + b;
}
};
//Create instance of struct
Sum sum;
int result = sum(1, 1); //result == 2
