Thread: My best C++ Programs

Do you mind if I rewrite your program and post a copy as my own? I'm interested in seeing how well I can do for modifying it and make it "better" in my eyes. First year programming, myself.

Was actually talking about the ones that started this thread. hehe... I'm working on the dice thing myself, using Member Functions and structs. Works nicely here at class.

Hey paro, you can either use parallel arrays or a struct, but the struct is much cleaner. And the toughest part is making an efficient shuffle. I did this program after about 2 months of C++, so it's definetly possible.

first year in high shcool and thats your semester project?! wow you guys must progress slow as hell our school does stuff with stacks and binary search trees,advanced algorithms and the like...

I doubt that, unless your school has problems with the APCS curriculum.

Well to begin, try to think up a good shuffling algorithm. I've thought up 3 already and I'm working on a fourth using linked lists. If you do a real shuffle and actually make a deck, the same card will never appear twice. Use suits, it makes it look better. And by the way, this will be REALLY FREAKIN HARD without arrays. So go ahead and learn those first.

Hehe, I remember the first program I really "tried" at was a game of 21. It was absolute crap- global variables and worse, it didn't even allow you to actually "play" the game...

Code:

#include <iostream.h>
#include <stdio.h>
#include <conio.h>
#include "randoma.h"

int ucard; 
int dcard;
int ccard;

int PlayGame();
void UpdateCount(int result, int &wins, int &losses, int&draws);
char AskRepeat();
void Report(int wins, int losses, int draws, int ng);

int main() {
	int wins = 0, losses = 0, draws = 0;
	char answer; int nogame = 0;
	do {
		int result; nogame++;
		result = PlayGame();
		UpdateCount(result, wins, losses, draws);
		answer= AskRepeat();
			ucard = 0;
			dcard = 0;
			ccard = 0;
	} while ((answer != 'N') && (answer != 'n'));
	Report(wins, losses, draws, nogame);
	return(0);
}

int PlayGame()
{
	int ncard = 0; int i = 0;
	cout << "How many card do you want? ";
	cin >> ncard; cout << endl << "You: ";
	for (i = 0; i != ncard; i++) {
		ccard= (random(10)+1);
		ucard+=ccard;
		cout << "  " << ccard;
	}
	cout << " = " << ucard;
	cout << endl << "Computer: ";
	for (i = 0; i != 3; i++) {
		ccard= (random(10)+1);
		dcard+=ccard;
		cout << "  " << ccard;
	}
	cout << " = " << dcard;
	cout << endl;
	int tog = 0;
	if (dcard < 22 && ucard < 22) {

		if (dcard == ucard) tog = 1;
		if (dcard > ucard) tog = 2;
		if (ucard > dcard) tog = 3;

	}
	if (dcard > 21) tog = 4;
	if (ucard > 21) tog = 5;
	if (dcard > 21 && ucard > 21) tog = 6;
	if (tog == 1 || tog == 6) cout << "\nOoh, a tie!\n";
	if (tog == 2 || tog == 5) cout << "\nHeh, you lose.\n";
	if (tog == 3 || tog == 4) cout << "\nYay! You win!\n";
	return (tog);
}

void UpdateCount(int result, int&wins, int&losses, int&draws)
{
	switch (result) {
	case 1: draws++; break;
	case 2: losses++; break;
	case 3: wins++; break;
	case 4: wins++; break;
	case 5: losses++; break;
	case 6: draws++; break;
	}
}

char AskRepeat() 
{
	char tstr;
	while (tstr != 'y' && tstr != 'Y' && tstr != 'n' && tstr != 'N') {
		cout << "\n Play again (Y/N)?  ";
		cin >> tstr;
	if (tstr != 'Y' && tstr != 'y' 
		&& tstr != 'n' && tstr != 'N') {
		cout << "Please enter yes or no." << endl; }
	}
	return (tstr);
}

void Report(int wins, int losses, int draws, int ng)
{
	system("cls");
	cout << "\n" << "Your wins = " << wins << endl;
	cout << "Computer wins = " << losses << endl;
	cout << "Draws = " << draws << endl;
	cout << "Total games = " << ng << endl;
	cout << '\n';
	return;
}

paro,
you were asking if there was a simpler way to make
it so an ACE in blackjack can be worth 1 or 11,
well i was thinking something like this, i hope
it helps:

ACE = 11
SUM = the sum of all the cards, ACE being 11

if SUM > 21 then ACE = 1
check SUM again
if SUM > 21 you lose

thought by me in a yippy!,

ill try that, and i already know a little about arrays
