Function’s Return Value

Question:
I’d like to know how can I make a return of a function’s local variable (for example, a reference to it) not using pointers technique?

Answer:
You have tow options: either return the local vriable by value or make it a local static variable and return a reference to it:

int f(){ int n = 5; return n;}int& f(){ static int n = 5; return n;}
