Question

I’m trying to studdy some performace things…
this question may sound stupid, but I’ll give it a try.
Let’s assume each function has 100 lines of same code.
or does this difference dosn’t realy metter?
which one will be faster on execution in main function:

struct A
{
    static void f()
         {
               cout << "static one";
         }
};

or this one:

void f()
{
   cout << "non static";
}

int main()
{
      A::f();
      f();
}

Answer 1

There’s no difference, the compiler works out the address at compile time and dispatches execution to it in one step at run-time (if it doesn’t inline it, which it’s equally able/likely to do with either).
