11 Year Old's Algorithm in C++

Why would you roll dice and do this simple task manually?  Just write a code to do it for you if you'd like to use this algorithm.

//To begin, a dice is rolled five times, with each numbered result documented.This then leaves you with a code, such as 12345. This result is already categorized in a dictionary, next to which is a word(which is ‘apathy’ in this instance).
//DiceYou then repeat this process six times and then band all the words together.You now have at your disposal an entirely bespoke and very long password that even the most powerful of computers will struggle to crack.
//Add a random character at the end and you’ve got an even stronger password, such as : apathy / sew / fungal / title / larch / maul / %.

//Required libraries
#include<iostream>      //cin, cout, endl
//#include<conio.h>       //_getch() that replaced the old getch()
#include<string>        //string
#include<fstream>       //ifstream
#include<Windows.h>     //Sleep(), srand(), rand()
#include<time.h>        //time()
#include<cmath>         //pow()


//Namespace specified to avoid using std:: with cin, cout, endl, ...

    }//end of for loop of generating 5 random words
