1. Take the code change it to use references to be more efficient and safe. (If you don't expect the variable to change in the function, do not allow it to change)

#include <iostream>
#include <string>

using namespace std;

string askText(string prompt);
int askNumber(string prompt);
void tellStory(string name, string noun, int number, string bodyPart, string verb);

int main()
{
cout << "Welcome to Mad Lib. ";
cout << "Answer the following questions to help create a new story. ";
  
string name = askText("Please enter a name: ");
string noun = askText("Please enter a plural noun: ");
int number = askNumber("Please enter a number: ");
string bodyPart = askText("Please enter a body part: ");
string verb = askText("Please enter a verb: ");
  
tellStory(name, noun, number, bodyPart, verb);

return 0;
}

string askText(string prompt)
{
string text;
cout << prompt;
cin >> text;
return text;
}

int askNumber(string prompt)
{
int num;
cout << prompt;
cin >> num;
return num;
}

void tellStory(string name, string noun, int number, string bodyPart, string verb)
{
cout << " Here's your story: ";
cout << "The famous explorer ";
cout << name;
cout << " had nearly given up a life-long quest to find ";
