[C++] Black Jack in the Console. 4 Player.
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.
Code:
#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;
}
int main()
{
int Cards[52], picked[52];
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++)
{
int RandNumber = rand() % 52;
while(picked[RandNumber] == 1)
RandNumber = rand() % 52;
picked[RandNumber] = 1;
Cards[i] = RandNumber;
}

// Display out shat now.
// Row 1 is empty/margin from gotoPosition
