What does the '&' operator do in C++?
- by rascher
n00b question. I am a C guy and I'm trying to understand some C++ code. I have the following function declaration:
int foo(const string &myname) {
cout << "called foo for: " << myname << endl;
return 0;
}
How does the function signature differ from the equivalent C:
int foo(const char *myname)
Is there a difference between using string *myname vs string &myname? What is the difference between & in C++ and * in C to indicate pointers?
Similarly:
const string &GetMethodName() { ... }
What is the & doing here? Is there some website that explains how & is used differently in C vs C++?
