Keeping track of how many times a function is called is easy when passing the counter as an argument into the function. It's also easy when returning a one from the called function. But, I do not want to go that route. The reason behind this is because it seems like bad programming (letting the function know too much information). Is there a better way to keep track of how many times this function has been called?
I'm just looking for concepts that I could study. Providing code examples is not neccessary, but might be helpful.
Edit: I'm not actually looking for profiling tools. Let me add some code to get my point across. Because scope for funcCounter ends in main, I have no way of getting back a variable from myFunction that will increment funcCounter. I could possibly return 1 from myFunction and then increment funcCounter that way, but this doesn't seem like very good programming. Is there another way to do it?
int main()
{
int funcCounter = 0;
char *mystring = "This is a silly function.";
myFunction(mystring);
cout << "Times function is called: " << funcCounter << endl;
return 0;
}
void myFunction(char *mystring)
{
cout << mystring << endl;
}
