Welcome. One piece of advice, make sure you word your questions very clearly, we don't know what you're thinking and we can't see what your working on unless you tell/show us. On that note, I would certainly love to help you, but I don't understand your question.

I think you mean that you would like to use the return value from a function as an argument for another function:

void display (int);        //declare display function

int calculate() {          //define calculate function
  return (6+4);
}

display( calculate() );  //call display() with calculate() return value as argument


void display(int paramValue) {  //define display()
  cout << paramValue << endl;
}
