VC++方块旋转设计

1、成绩：实 验 报 告课程名称：Visual C+面向对象与可视化程序设计实验项目：方块旋转设计姓 名：专 业：计算机科学与技术班 级：学 号：计算机科学与技术学院2016 年 11 月 19 日一、 实验目的1. 提高VC+程序设计能力2. 综合运用所学知识设计方块旋转程序二、 实验内容设计一个程序，能够显示一个方块，然后方块可以在窗口中旋转。三、 实验步骤1. 打开VS2012新建WIN32项目2. 选好保存地址，写好文件name3. 进入项目，打开cpp文件编写代码4. 其中实现旋转的方法（建立piont 数组放入方块四个顶点坐标，用r为半径的for循环建立四个点，每次四个点移动统一的角度

2、，方块便旋转了）四、 运行结果五、 程序代码/ ProjectRECT.cpp : 定义应用程序的入口点。/#include "stdafx.h"#include "ProjectRECT.h"#include<math.h>#define MAX_LOADSTRING 100#define PI atan(1.0)*4/ 全局变量:HINSTANCE hInst;/ 当前实例TCHAR szTitleMAX_LOADSTRING;/ 标题栏文本TCHAR szWindowClassMAX_LOADSTRING;/ 主窗口类名/ 此代码模块中
