Bit O' Help Please

[The Brain]

I am just trying to draw a simple card to dos console.. I am following this tutorial.. and for some reason, this small program is yielding over 102 compilation errors... compiler doesn't seem to like the #define's but they are written just like the tutorial.

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

#define WHITE   BACKGROUND_RED		| \ 
                BACKGROUND_GREEN	| \ 
                BACKGROUND_BLUE		| \
                BACKGROUND_INTENSITY

#define RED	FOREGROUND_RED | FOREGROUND_INTENSITY	
#define BLACK   0


typedef struct card
{
	unsigned int face_value;
	char suit;
	card *next;

	card(){next=NULL;}

}*mycard;


int main(void)
{
	HANDLE hOut;

	hOut = GetStdHandle(STD_OUTPUT_HANDLE);

	card new_card = new card;

	srand(GetTickCount());	

	new_card->face_value = static_cast<unsigned>rand()%9+2;

	new_card->suit = static_cast<char>rand()%4+3;

	SetConsoleTextAttribute(hOut, new_card->suit<2?WHITE|RED:WHITE|BLACK);

	cout     << new_card->face_value  << new_card->suit << "  \n"
		 << "   \n" 
		 << " " << new_card->suit << " \n"
		 << "   \n" 
		 << " " << new_card->suit << new_card->face_value;

	return 0;

}

You should not have any spaces after the backslash.
Probably should write like:

#define WHITE   (BACKGROUND_RED		| \
                BACKGROUND_GREEN	| \
                BACKGROUND_BLUE		| \
                BACKGROUND_INTENSITY)

#define RED	(FOREGROUND_RED | FOREGROUND_INTENSITY)
#define BLACK   0

I'm not sure if it is legal to use
typedef struct name {}*;
But then if it works, it works.

I think it should be:
card* new_card = new card;
Though maybe your typedef takes care of that, if it works.

Also, your casts arent written correctly.
For example:
static_cast<unsigned>(rand()%9+2)
not
static_cast<unsigned>rand()%9+2

Awesome help from the c++ witch

#include<iostream>
#include<cstdlib>
#include<cstring>
#include<windows.h>
using namespace std;

#define WHITE BACKGROUND_RED|BACKGROUND_GREEN|BACKGROUND_BLUE|BACKGROUND_INTENSITY
#define RED   FOREGROUND_RED|FOREGROUND_INTENSITY	
#define BLACK 0


typedef struct card
{
	unsigned int face_value;
	char suit;
	card *next;

	card(){next=NULL;}

}*mycard;


int main(void)
{
	HANDLE hOut;

	hOut = GetStdHandle(STD_OUTPUT_HANDLE);

	mycard new_card = new card;

	srand(GetTickCount());	

	new_card->face_value = static_cast<unsigned>(rand()%9+2);

	new_card->suit = static_cast<char>(rand()%4+3);

	SetConsoleTextAttribute(hOut, new_card->suit<5?WHITE|RED:WHITE|BLACK);

	cout     << new_card->face_value    << new_card->suit << "   \n"
		 << "     \n" 
		 << "  "  << new_card->suit << "  \n"
		 << "     \n" 
		 << "   " << new_card->suit << new_card->face_value;

	return 0;

}

Although I couldn't figure out why the #defines where whacked.. I just put everything on a single line. Compile and run.. you'll get a descent looking playing card

Hi,

You have a space problem in your first #define. And, when I run it, the white background of the card extends all the way to the right of the console window.

It's still pretty neat.

The board keeps adding that space in my first #define (the typed version looks ok before I post, but after I post the board adds the space for some reason)

Here is what I get when I run the program. Spacing problems will occur right now when the face value is a double digit but I can handle that as a seperate case:
