Ok so I have this game of RPS, I changed a lot of parts of it and got it all running correctly, but I have came to the following problem:
I built the game, added in some ASCII art to represent each item (Rock, Paper, Scissors)
I got the game to work with no errors, it actually plays but I forgot when I was building it that I needed it to have classes.
I NEVER really use classes because I have only really made really simple small things written in C++ which don't even need them. (I find programming languages very hard to comprehend)
So I was wondering if someone could take a look at it and maybe help be get each object (I think that's what it's called) put into classes, this would be giving Rock, Paper and Scissor their own separate classes.
Here's the code:

cout << " rock, 2 for paper, and 3 for scissors\n";

Classes are a HUGE part of programming and they make everything a lot more organized and easier to read. So you really do need to learn them if you plan on continuing on in the programming field. From what you said, it sounds like you're making this program for a class, so I'm not going to do the whole thing for you, however I will make the rock class. It'd probably look like this:
I'm not really sure what other methods you'd need to have in there, so I just made the one print.
Anyways, like I said above, classes are really important to programming, well at least OOP. So I encourage you to become more familiar with them. Some good places to learn, are thenewboston.org and learncpp.com. Here is the first video tutorial on classes from thenewboston.
class Rock
{
public:
static void print()
{
cout <<" . -- ~~~ -- .\n";
cout <<" .-~ ~-.\n";
cout <<" / \\n";
cout <<" / \\n";
cout <<" | |\n";
cout <<" | |\n";
cout <<" | |\n";
cout <<" \ /\n";
cout <<" \ /\n";
cout <<" `-. .-'\n";
cout <<" ~- . ___ . -~\n";
}
};

Hmm, wasn't really for a class (as in school/college) just something I wanted to try, as i thought it wouldn't be too hard.
But thanks this will help me quite a bit i'm sure.

You could have a class named "draw" where you had functions to draw scissors, rock and paper for example.
Then just include the class like:
#include "draw.hpp"
Then call the public functions you declared.
Like so:
draw.hpp:
draw.cpp:
The new "main.cpp":
Just a side note, this may not compile as is but its probably close. You could also pass through compchoice and output the necessary lines using the if statements you created too.
Then just include the class like:
#include "draw.hpp"
Then call the public functions you declared.
Like so:
draw.hpp:
#if !define _DRAW_HPP_
#define _DRAW_HPP_
class Draw{
public:
Draw();
~Draw();
void drawRock();
void drawScissors();
void drawPaper();
};
#ENDIF //_DRAW_HPP_ draw.cpp:
#include "draw.hpp"
#include <iostream>
using namespace std;
Draw::Draw(){
}
Draw::~Draw(){

cout <<" .-~ ~-.\n";
cout <<" / \\n";

cout <<" / _ \ / _ \\n";
