Noob question function not being read.

[Badplum25]

Why wont this code work? Sorry im so nooby. Everything inside my addition function is not being read inside my main function.

#include <iostream>
#include <limits>
using namespace std;

void additionFunction();


int main()
{
    additionFunction();

    cout << ("Enter addition");
    cin >> a;

    cout << ("Enter addition");
    cin >> b;

    cout << "The answer is " << answer << endl;

    return 0;
}


    void additionFunction(){
    int a;
    int b;
    int answer = a + b;

    return answer;

}

Look at the very first example here: http://www.cplusplus.com/doc/tutorial/functions/
But do not stop there, read the whole page to understand how to fix it right.
