Greetings,
In some cases it would be useful to overload functions based on knowing if a variable is a compile-time constant or not. For example:
void foo(int size)
{
cout << 1 << endl;
}
template <int Size>
void foo(int Size)
{
cout << 2 << endl;
}
int main(int argc, char * argv[])
{
foo(argc); // outputs 1
foo(sizeof(int)); // outputs 2
}
Regards,
