C++练手小游戏3——万花筒
作者:互联网
概述
原项目是旋转蛇错觉图案,但我这里修改了一下,只随机生成同心圆及其颜色。
实现效果和涉及的知识
初步接触for循环
文件结构
具体代码
FQF_RotCir.cpp
// FQF_RotCir.cpp : 此文件包含 "main" 函数。程序执行将在此处开始并结束。
//
#include <iostream> // C++ STL 输入输出库
#include <graphics.h> // 绘图函数库,非cpp STL,是TurboC扩展库(EasyX)
#include <conio.h> // console input/output的简写,非cpp STL,定义了通过控制台进行输入输出的函数,如getch()
#include "data.h"
#include "RotPie.h"
