[C++] Black Jack in the Console. 4 Player.

[MattSmith]

I went to a college visit on Friday, talked to the head of the computer science department and this is their final project for Computer Science 1. He gives these guys a month to make this thing, I sat here in 2 hours and typed it out from start to finish and emailed it too him. And I'm suppose to pay fucking $28/year for this stuff I already know.. Anyways, here is my source, just compile it in an C++ compiler. Will only work in windows I believe, due to the includes.

#include <iostream>
#include <ctime>
#include <Windows.h>
#include <stdio.h>
#include <string>
#include <sstream>
	using namespace std;

void gotoPosition(int x, int y)
{
	HANDLE hConsole = GetStdHandle ( STD_OUTPUT_HANDLE );

	if ( INVALID_HANDLE_VALUE != hConsole )
	{
		int top_margin = 1;
		COORD pos = {x, y + top_margin};
		SetConsoleCursorPosition ( hConsole, pos );
	}
}

void clearRow(int y)
{
	gotoPosition(0, y);
	cout << "                                                                               " << endl;
}

	char CardTypes[13] = {'A', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'J', 'K', 'Q'};
	char CardSuits[4] = {char(3), char(4), char(5), char(6)};

	srand(time(NULL));

	// Build the stack of cards.
	for(int i = 0; i<52; i++)
	{

But see, just because you can come up with the final solution, doesn't mean your code is college standard. For instance, one of my courses last semester marked us primarily on the quality of our code. That code looks like a bit of a mess.

[The Unintelligible]

Spaghetti code.

It's cleaner than the crap the instructor was writing.. Feel free to watch where he explains the project: (The video he sent me to get a feel for his teaching)

Remembering also that intro courses assume no knowledge. All intro courses are easy.

Pisses me off that in order to get to learning something, I have to pay for the shit I already know. That's a lot of money to poor out for little gain in knowledge.

Sometimes with the intro classes they'll let you sit an exam for a free credit if you can show the subject coordinator you have the necessary experience/knowledge already (i.e. work experience, previous degree, diploma etc.)

[MattSmith]

I still have to pay for the class. It's whatever, I think I'm doing dual enrollment next year as a senior and the school will pay for classes I take during that.

[Artificial]

Well if you get the free credit you don't have to pay for the class. It's like starting University after a Tafe/College diploma. If you can prove you've done the prerequisites, they're not going to make you take them again.

[MattSmith]

In american uni's ? If so I'll email the director of computer science of the uni and see what comes of it.

Well you haven't done a diploma or anything so if they do allow it it'd purely be up to the subject coordinators discretion. As you're still in highschool, I doubt they're going to give it to you.

Well, I'm back to my high school paying for it. So it doesn't bother me much if I'm not paying.
