输出窗口背景颜色随机变化

void test01() {
	initgraph(450, 400);
	//setbkcolor(RGB(128, 0, 128)); //RGB配置颜色
	//cleardevice();
	srand((unsigned int)time(NULL));

	//文字输出
	//图形窗口只能显示字符串
	settextstyle(10, 10, _T("黑体"));
	outtextxy(100, 200, _T("dove"));
	Sleep(3000);
	
	while (1) {
		setbkcolor(RGB(rand() % 256, rand() % 256, rand() % 256));
		cleardevice();
		Sleep(1500);
	}
}

窗口显示数字

//把数字转为字符串
char str[10] = " ";
char *NumToChar(int num) {
	sprintf(str, "秒表：%d", num);
	return str;
}

void test02() {
	initgraph(600, 450);
	srand((unsigned int)time(NULL));
	int i = 0;
	
	while (!_kbhit()) //检查控制台窗口的按键是否被按下
	{
		setbkcolor(RGB(rand() % 256, rand() % 256, rand() % 256));
		outtextxy(100, 240, "继续游戏");
		outtextxy(0, 0, NumToChar(i));
		i++;
		Sleep(1000);
	}
}

绘制简单的直线、圆、矩形、填充圆

void test03() {
	initgraph(600, 450);
	setbkcolor(WHITE);
	cleardevice();
	setlinecolor(BLACK);
	line(0, 0, 600, 450);
	circle(300, 225, 100);
	rectangle(200, 125, 400, 325);
	setfillcolor(MAGENTA);
	fillcircle(100, 100, 50);
}

绘制一个运动的圆

void test04() {
	initgraph(600, 450);
	setbkcolor(WHITE);
	setlinecolor(BLACK);
	setfillcolor(MAGENTA);

	int x = 100;
	int y = 100;
	while (1) {
		cleardevice();
		line(0, 0, 600, 450);
		circle(300, 225, 100);
		rectangle(200, 125, 400, 325);
		fillcircle(x++, y++, 50);
		Sleep(100);
	}
}

加载图片

void test05() {
	IMAGE img;
	loadimage(&img, "algorithm.png");
	int width = img.getwidth();
	int height = img.getwidth();
	initgraph(width, height);
	putimage(0, 0, &img);
}

int main(){
	//test01();
	//test02();
	//test03();
	//test04();
	test05();

	getchar();
	closegraph();
	return 0;
}
