CS 10 SI Classroom Session 5 - Removing duplicated code into a function

annoying_validation.cpp

#include <iostream>

using namespace std;

int main() {
  string twoCharInput = "";
  string fiveCharInput = "";
  string tenCharInput = "";

  // Make user continue entering word until it is the
  // correct size.
  do {

       << "The ten character word is " << tenCharInput << endl;

  return 0;
