Found out what i need to sorta do.
One problem can not understand how to do it: Repeat Function

How.
Loop may not do it as it loops what i don want to loop!

EX:

#include <iostream>
#include <string>
#define sentence cout << sentence << endl;
using namespace std;
int main()
{
string sentence = ""; // Want to Repeat this base Function.
cout << "Write Something: ";
cin sentence;

? Have lost myself!
