Need help converting this to h files

[mt106250]

Hey guys, I don't understand how to convert this rock paper scissors game to multiple files such as header file, cpp file, and main cpp file.

I read all the materials and lecture slides about it, and I still don't understand what to put in the header file with classes

#include <iostream>
#include <cstdlib>
#include <ctime>
#include <fstream>
using namespace std;

int main() {
	enum choice {ROCK, PAPER, SCISSORS};
	
	choice select;
	char user;
	bool play_again;
	string play;
	int num_games = 0;
	int player_wins = 0;
	int computer_wins = 0;
	bool tie = false;
	int num_ties = 0;
	
	ofstream outfile;
	ifstream infile;
	
	
		
		
	// Ask the user if they would like to play.
	cout << "By playing this game, do you want to save your data? (y or n): ";
	cin >> play;
	
	// If they answer yes, then play, otherwise no.
	if(play == "y" || play == "Y"){
		play_again = true;
		num_games++;
		infile.open("RockPaperScissors.txt");
		infile >> player_wins >> computer_wins;
		infile.close();
		}
	
	// Start playing the actual game if they want to play.
	while(play_again != false){
		cout << endl << endl << "Rock, Paper, or Scissors? ('r', 'p', or 's'): " ;
		cin >> user;
		cout << endl;
		
		
		// Taking the input and applying it to constant in enum.
		if (user == 'r' || user == 'R'){
			select = ROCK;
			}
		
		else if (user == 'p' || user == 'P'){
			select = PAPER; 
			}

			select = SCISSORS;
			}
		
		else {
			cout << "Come on... That's not an option." << endl;
			cout << endl << endl << "Rock, Paper, or Scissors? ('r', 'p', or 's'): " ;
			cin >> user;
			}
		
		
		long  seed = time(NULL); // gets current time
		srand(seed);
		
		// Computer's random selection
		int computer = rand();
		
		//DEBUG: cout << computer << endl;
		
		// Computer's random selection
		computer = rand() % 3;
		
		//DEBUG: cout << computer << endl << endl;;
		//DEBUG: cout << "Here is a test: " << select << endl;
		
		// In the event of a tie, make both players make a new selection and re-evaluate them.
		
		while(computer == select){
			cout << endl << "It's a tie, Pick again please: ";
			cin >> user;
			
			// This is repeated... :/
			if (user == 'r' || user == 'R'){
				select = ROCK;
				}

				select = PAPER; 
				}
			
			else if (user == 's' || user == 'S'){

				cout << "Rock, Paper, or Scissors? ('r', 'p', or 's'): " ;
				cin >> user;
				}
			
			computer = rand() % 3;
			}
		
		
		// Applying the computer's selection to the appropriate value in enum.
		choice cpu_select;
		
		if (computer == 0){
			cpu_select = ROCK;
			}
		
		else if (computer == 1){
			cpu_select = PAPER; 
			}
			
		else if (computer == 2){
			cpu_select = SCISSORS;
			}
		
		
			
		// Displays each respective selection.
		cout << endl << endl << "Your selection is " << select << endl;
		cout << "The computer selects " << cpu_select << endl;
				
		// Win conditions

		if ((select == ROCK && cpu_select == SCISSORS) || (select == PAPER && cpu_select == ROCK) || (select == SCISSORS && cpu_select == PAPER)){
				cout << endl << "You win." << endl;
				player_wins ++;
			}

		else if((cpu_select == ROCK && select == SCISSORS) || (cpu_select == PAPER && select == ROCK) || (cpu_select == SCISSORS && select == PAPER)){
			cout << endl << "The computer wins." << endl;
			computer_wins ++;
			}
		
		// Show the results of all the games.
		cout << "The player has won " << player_wins << " games." << endl;
		cout << "The computer has won " << computer_wins << " games." << endl;
		
		
		// Ask if the player would like to play again.
		cout << endl << endl << "Would you like to play again?: ";
		cin >> play;
		
		// Exit the loop if the player chooses no.
		if (play == "n" || play == "N"){
			play_again = false;
			}
		else if (play == "y" || play == "Y"){
			num_games++;

	outfile.open("RockPaperScissors.txt");

[AbstractionAnon]

Since you have no classes in your program and all your logic is in main (ever hear of functions?), there is not really anything to move to .h and .cpp files.

Line 67: srand() should only ever be called once in a program. Calling it multiple times (inside a loop) causes it to reset the random number generator.

Like what AbstractionAnon suggested.. You should break it down into Functions! It would make your code so much easier to read!

Here is a set of some Good Tutorials I've used in the past:

Functions: https://youtu.be/aOmfWxbm4mQ?list=PLmpc3xvYSk4wDCP5zjt2QQXe8-JGHa4Kt

From Lessons 25-34 Talks about Functions to Classes..

This is what I've been working on Learning and Practicing with <fstream>
I have almost as much code and mine is so much easier to read.. and yes I could have a MapHandler class w/ member functions just haven't gotten there yet.. still testing and playing with the code.

#include <iostream>
#include <fstream>
#include <string>
#include <vector>
#include <stdlib.h> //for exit() function

{
	string fileName = "Map_Outpost.txt";
	vector<string> Map;


	//WriteToFile(fileName);
	//ReadFromFile(fileName);
	LoadMap(Map, fileName);
	PrintMap(Map);


	system("PAUSE");//TESTING ONLY
	return 0;
}
