This is awesome!!! I have nerver been thought I could write a C ++ program alone. Now I can !

#include <iostream>

int readNumber()
{

using namespace std;
int x=0;
cout << "please input an intger: ";
cin >> x;
return x;

}

int addnumber()
{
int sum;
int i = readNumber();
int j = readNumber();
sum = i + j ;
return sum;

}

void writeAnswer()
{
using namespace std;
//“This is the answer: “<<
cout << addnumber() << endl;

}

int main()
{
//addnumber();
writeAnswer();
return 0;

}
