How to return the response from an asynchronous function?

Simple C++ Function help?

• I just started Sam's Teach Yourself C++ in an Hour a Day (21 days) and I haven't been having problems yet but there is one function that is stumping me. I have tried to comprehend the instructions given yet my brain has turned to mush and I can't figure it out. Here is the code: #include <iostream> int Add (int first, int second) { std::cout << "Add() recieved"<< first << " and "<< second << "\n"; return (first + second); } int main() { using std::cout; using std::cin; cout << "I'm in main()!\n"; int a, b, c; cout << "Enter two numbers: "; cin >> a; cin >> b; cout << "\nCalling Add()\n"; c=Add(a,b); cout << "\nBack in main().\n"; cout << "c was set to " << c; cout << "\nExiting...\n\n"; char response; std::cin >> response; return 0; } Where is says "Enter two numbers," the instructions say: The program prompts the user for two numbers . The user types each number, separated by a space, and then presses the Enter key. The numbers the user enters are placed in the variables a and b on lines 17 and 18. Every time I try to accomplish this, I build a solution and there are errors all over the place. How would I go about submitting the two numbers into the code and not getting those errors?

  Works fine for me.
