how do I get the value from index in this function I made?

[Noobscratcher]

Hello I'm having problems with:

1.)How do I get the value of interger variable index outside of this function scope.

2.)How can I use this interger variable index with another function call.

I tried to use return but that didn't give me the results I wanted.

//index Assigner Function
int IndexAssigner(int clicktype, int index)
{

  int xm;

  int ym;

  SDL_GetMouseState(&xm,&ym);


  if(clicktype == 1)
  {

  
        //Index 1
        if(xm <= 100 && ym <= 100)
        {
        
          cout << "Hello this is a test" << endl;
          index = 1;
          cout << index << endl;
        
        }
        
        //Index 2
        if(xm >= 200 && ym >= 200)
        {
        
          cout << "Hello this is a test 2" << endl;
          index = 2;
          cout << index << endl;
        
        }

       

  }

  
  return index;



}

thank you :)
