Overload Resolution in C++

[zbigniew]

Can someone explain me how overload resolution works in C++?

For example if I have function void f(char, int); and I will call
f('A', 3.1) or f(1.5, 3.1F) what would be the result?

Thanks

If you only have a single function called 'f', no overload is present.
Overload is only there if you have more than one function named 'f':

void f(char, int);
void f(long, double);

int main() {
f(0L, 0.0); // the latter is called
f('c', 42); // the former is called
}

Explaining how overload resolution "works" can take weeks. Please find
a decent C++ book and read the section/chapter on overloading.

Indeed. However, there are some rules that are followed, which are not
that complicated.
