Scope and return values in C++

Question

I am starting again with c++ and was thinking about the scope of variables. If I have a variable inside a function and then I return that variable will the variable not be \

Answer 1

When you return a value, a copy is made. The scope of the local variable ends, but a copy is made, and returned to the calling function. Example:

int funcB() {
  int j = 12;
  return j;
}

void A() {
  int i;
  i = funcB();
}

The value of j (12) is copied and returned to i so that i will receive the value of 12.
