Implementation example of C++ card drawing emulator

I was bored at school recently and wrote a card drawing simulator for everyone to entertain.

The code implements the following functions: card drawing interface, card drawing determination, animation playback, and archive.

1. Card draw interface and judgment

The technology is limited, and it is impossible to do as exquisite as Genshin Impact. The code is as follows (Note: This is not the complete code, don't copy it wrong)

printf("enter your name:");
	cin >> username;
	HANDLE handle = GetStdHandle(STD_OUTPUT_HANDLE);
	CONSOLE_CURSOR_INFO CursorInfo;
	GetConsoleCursorInfo(handle, &CursorInfo);
	 = false;
	SetConsoleCursorInfo(handle, &CursorInfo);
	printf("For each time : 0.6%% for gold and 6%% for purple\n");
	printf("P(gold) will increase After 73 times until 90 to 100%\n");
	printf("10 purples , as well as 1 gold, provides another chance\n");
	system("pause");
	char kk = _getch();
	if (kk == 'c')
		change();
	int r, waidegold = 0, ggold = 0, pple = 0;
	READ();
	
	srand(time(0));
	int n, m, i, j, gold = 0, pp = 0, big = 0, cnt = 0, total = 30;
	while (cnt < total) {
		system("cls");
		printf("Press 1.10\n");
		printf("You've rolled %d times rest:%d\n", cnt * 10, (total - cnt) * 10);
		printf("WAI:%d GOLD:%d PP:%d\n", waidegold, ggold, pple);
		++cnt;
		char k;
		bool chu = 0;
		k = _getch();
		Sleep(5);
		for (i = 1; i <= 10; ++i) {
			int r = random();
			++gold, ++pp;
			if (r <= p[gold] *MAXX ) {
				total++;
				//gold
				Play(1);
				chu = 1;
				if ((rand() % 2  ) && !big) {
					//wai
					big = 1;
					string tmp = changzhu[rand() % 8];
					printf("%d times Congratulations on your mistake %s\n", gold, tmp.c_str());
					DATA[++cnttt] = username;
					DATA[cnttt]  += ( gold / 10 + '0');
					DATA[cnttt] += (gold % 10 + '0' );
					DATA[cnttt] += "times : ";
					DATA[cnttt] += tmp;
					//printf("DATA[%d]= %s\n", cnttt, DATA[cnttt].c_str());
					Sleep(2000);
					system("pause");
					waidegold++;
				} else {
					big = 0;
					printf("%d times %s\n", gold, UP.c_str());
					DATA[++cnttt] = username;
					DATA[cnttt]  += ( gold / 10 + '0');
					DATA[cnttt] += (gold % 10 + '0' );
					DATA[cnttt] += "times : ";
					DATA[cnttt] += UP;
					//printf("DATA[%d]= %s\n", cnttt, DATA[cnttt].c_str());
					Sleep(2000);
					system("pause");
					ggold++;
				}
				gold = 0;
			}
			if (r >= MAXX * 0.94 || pp == 10) {
				//purple
				if (!chu)
					Play(0);
				chu = 1;
				printf("%d times a purple\n", pp);
				system("pause");
				pp = 0;
				pple++;
				if (pple % 10 == 0)
					total++;
			}
		}
	}

2. Archive

Including time acquisition and storage of results

Get time:

struct Time {
	int year, month, day, hour, minute, second;
};

Time gottime() {
	Time TIME;
	time_t now = time(0);
	tm *ltm = localtime(&now);
	 = 1900 + ltm->tm_year;
	 = 1 + ltm->tm_mon;
	 = ltm->tm_mday;
	 = ltm->tm_hour;
	 = ltm->tm_min;
	 = ltm->tm_sec;
	return TIME;
}

storage:

void read() {
	freopen("", "r", stdin);
	scanf("%d %d %d", &mxxwdgd, &mxxggd, &mxxple);
	fclose(stdin);
}
void putt(int waidegold, int ggold, int pple) {
	freopen("", "w", stdout);
	printf("%d %d %d", waidegold, ggold, pple);
	fclose(stdout);
}
void save(int waidegold, int ggold, int pple) {

	read();
	printf("RECORD: waide:%d not:%d ple:%d\n", mxxwdgd, mxxggd, mxxple);
	if (ggold > mxxggd) {
		printf("NEW RECORD!!!\n");
		putt(waidegold, ggold, pple);
		Sleep(3000);
	}

}
string changzhu[8] ;
string UP;
void READ() {
	freopen("", "r", stdin);
	cin >> UP;
	for (int i = 0; i <= 7; i++)
		cin >> changzhu[i];
	fclose(stdin);
}
void change() {
	freopen("", "w", stdout);
	string st;
	cin >> st;
	cout << st << endl;
	for (int i = 1; i <= 8; i++) {
		cin >> st;
		cout << st << endl;
	}
	fclose(stdout);
}
void read1() {
	freopen("", "r", stdin);
	char tmp[500];
	while (~scanf("%s", &tmp)) {
		DATA[++cnttt] = tmp;
	}
	fclose(stdin);
}
void data1(string stt) {
	freopen("", "w", stdout);
	Time s = gottime();
	printf("\n%d/%d/%d,%d:%d:%d\n", , , , , , );
	printf("%s\n", username.c_str());
	for (int i = 1; i <= cnttt; i++) {
		if (DATA[i] == ":" || DATA[i + 1] == ":")
			printf("%s", DATA[i].c_str());
		else
			printf("%s\n", DATA[i].c_str());
	}
	fclose(stdin);
	fclose(stdout);
}

By the way, since I didn't trust rand() very much, I created a random function myself

int random() {
	int a[6], k = 0;
	for (int i = 0; i < 6; ++i)
		a[i] = rand() % 10;
	for (int i = 0; i < 6; ++i)
		k = k * 10 + a[i];
	return k;
}

3. Animation playback

Very simple.

void Play(bool ggg) {
	system("cls");
	if (ggg == 0) {
		setcolor(purple, white);
	} else {
		setcolor(black, yellow);
	}
	int i, j, k;
	for (i = 1; i <= 20; i++) {
		GoToxy(i, i + 20) ;
		printf("\\");
		Sleep(40);
		if (ggg == 1)
			Sleep(15);
	}
	i = 20, j = 50, k = 1;
	int r = 1;
	if (ggg == 1)
		for (; r <= 10; r += k, ++k) {
			GoToxy(i - r, i + 20 - r);
			for (int i1 = i - r; i1 <= i + r; ++i1)
				printf("_");
			for (int i1 = i - r + 1; i1 <= i + r - 1; ++i1) {
				GoToxy(i1, i + 20 - r);
				printf("|");
				GoToxy(i1, i + 20 + r);
				printf("|");
			}
			GoToxy(i + r, i + 20 - r);
			for (int i1 = i - r; i1 <= i + r; ++i1)
				printf("_");
			Sleep(55);
		}
	system("cls");
	setcolor(white, black);
}

That's it, the complete code is as follows. Usage tutorial
