Write a program that prompts the user to enter three words. The program will then sort the words in alphabetical order, and display them on the screen. The program must be able to support words with both uppercase and lowercase letters. You must use C style strings (string class).

#include <iostream>

#include<bits/stdc++.h>

using namespace std;

bool sorter(string a, string b)

{

   return a<b;

}

int main(){

   string wordList[3];

   string word;

   for (int i = 0; i < 3; i++){

       cout<< "Enter word: ";

       cin>> word;

       wordList[i] = word;

   }

   sort(wordList, wordList+3, sorter);

   for (int i = 0; i < 3; i++){

       cout<< wordList[i]<< "\n";

}

}

Explanation:

The C++ source code prompts the user for string words that are appended to the wordList array. The array is sorted with the sort() function from the C++ bits library. The finally for loop statement prints out the items in the array.
