Simple C++ Problem

Probably a simple fix, but does anyone know what a int& parameter is requiring? I thought it would be a memory address but Visual Studio is saying otherwise. Thanks!

It's a reference , not a pointer.

Just pass the value normally.

It's asking a reference to an integer variable, it's not a pointer.

 

For example:

void changeMyVar(int& var)
{
  var = 100;
}

int main()
{
  int myVar = 0;
  changeMyVar(myVar);
  std::cout << myVar;
  return 0;
}

will change the value of the main's myVar variable to 100.

I see, thanks! One more question, I'm trying to implement sorting algorithms that work with floats, integers, and strings. And since I have to swap positions of items during the Partition stage of Quicksort, what type should I be using for the temporary variable to store items during swap?
