Hi all! Info on a console game

[ggggiuseppe]

Hi,
this is my first message here. Great site!
I'm creating a console game based on an italian game, called "Tombola"
http://en.wikipedia.org/wiki/Raffle.

Pratically, is a game with a main board composed by 90 number and other small tables where there are some of the 90 number. Then someone extract a number (1..90) from a bag and the others checks if they have that number.
The winner is the one who make "tombola", that is the combination of all the number on a small tables. Btw, there are other minor combination: "ambo" (2 on a line), "terno" (3 on a line), "quaterno" (4 on a line), "cinquina" (5 on a line)

I created the table with the 90 number and 3 functions (one to draw, one to extract the number and another one to point out which number is extracted).
This is the code:

#include <iostream>
#include <iomanip>
#include <ctime>
#include <windows.h>
using namespace std;

void dis_tab (int coordX[], int coordY[]);
int estrai_num ();
void dis_num (int coordX[], int coordY[], int num);

int main ()
{
	INPUT_RECORD Input;
	DWORD num_eventi;
	int X[90] , Y[90];
	int num;
	
	SetConsoleTitleA("Tombola");
	
	dis_tab (X, Y);	
	
	cout << "Premi INVIO per estrarre un numero." << endl;

	while (true) {
		ReadConsoleInput(GetStdHandle (STD_INPUT_HANDLE), 
											&Input,
											1,
											&num_eventi);
		if (Input.EventType == KEY_EVENT) {
			if (Input.Event.KeyEvent.bKeyDown &&
				Input.Event.KeyEvent.wVirtualKeyCode == 0x0D) {
					num = estrai_num ();
					dis_num (X, Y, num);
			}
		}
	}

	return 0;
	
}

void dis_tab (int coordX[], int coordY[])
{

	cout << (char)218;
	for (int i = 0; i < 9; i++) {
		for (int j = 0; j < 2; j++)
			cout << (char)196;		
		cout << (char)194;			
	}
	for (int i = 0; i < 2; i++)
		cout << (char)196;
	cout << (char)191 << endl;
	int k = 1;
	for (int i = 0; i < 8; i++) {
		cout << (char)179;
		for (int j = 0; j < 10; j++) {
			coordX[k-1] = (j * 3) + 1;
			coordY[k-1] = (i * 2) + 1;
			cout << setw (2) << k++;
			cout << (char)179;
		}
		cout << endl;
		cout << (char)195;
		for (int i = 0; i < 9; i++) {
			for (int j = 0; j < 2; j++)
				cout << (char)196;
			cout << (char)197;		
		}
		for (int i = 0; i < 2; i++)
				cout << (char)196;
		cout << (char)180 << endl;
	}
	cout << (char)179;
	for (int i = 0; i < 10; i++) {
			coordX[k-1] = (i * 3) + 1;
			coordY[k-1] = 17;
			cout << setw (2) << k++;
			cout << (char)179;
		}
	cout << endl << (char)192;
	for (int i = 0; i < 9; i++) {
		for (int j = 0; j < 2; j++)
			cout << (char)196;
		cout << (char)193;		
	}
	for (int i = 0; i < 2; i++)
				cout << (char)196;
	cout << (char)217 << endl;
}

int estrai_num ()
{
	static bool ext[90], prim_call = true;
	int num;
	 
	if(prim_call == true) {
        srand (time (NULL));
        prim_call = false;
    }

	do {
		num = rand () % 90 + 1;
	} while (ext[num-1] == true);
	ext[num-1] = true;

	return num;
}

void dis_num (int coordX[], int coordY[], int num)
{
	CONSOLE_SCREEN_BUFFER_INFO schermo;
	WORD col_orig;
	COORD punti, punti_orig;
	HANDLE outhandle = GetStdHandle (STD_OUTPUT_HANDLE);
	
	GetConsoleScreenBufferInfo (outhandle, &schermo);
	col_orig = schermo.wAttributes;
	punti_orig = schermo.dwCursorPosition;

	punti.X = coordX[num-1];
	punti.Y = coordY[num-1];
	SetConsoleCursorPosition (outhandle, punti);
	SetConsoleTextAttribute (outhandle, FOREGROUND_BLUE |
										FOREGROUND_INTENSITY |
										BACKGROUND_GREEN |
										BACKGROUND_INTENSITY);
	cout << setw (2) << num;
	SetConsoleCursorPosition (outhandle, punti_orig);
	SetConsoleTextAttribute (outhandle, col_orig);
}

I think this could be improved a lot, but now i'm out of idea. :)

Bye and thanks.


Edit: I think i haven't explained well enough :) because my first language is italian. Btw, ask me if it is not clear. Thanks Again
