Answer 2

#include <iostream>
using namespace std;

int addition( int x, int y );

int main(){

int x,y;
cout<< "Enter the first digit!"<<endl;
cin>>x;

cout<< "Enter the second digit!"<<endl;
cin>>y;

cout<< "The sum of the digits is "<< addition(x, y) << endl;

return 0;
}

int addition(int x, int y){

int sum = x + y;
return sum;

}

Answer 3

... "undefined reference to "addition()' "

There is no function called "addition" in your program that takes no parameters.
