面向对象程序设计实验报告

1、成都理工大学面向对象程序设计报告 学 院： 信息科学与技术学院 课程名称： 面向对象程序设计 专业班级： 物联网工程三班 学生姓名： 李瑞超 学号： 201413060309 指导教师： 覃 章 健 完成时间：2015.05.27一、 实验设计内容与要求设计并完成一个基于MFC的计算器、要求实现如下基本计算功能(1) 需完成简单的双目运算，例如加、减、乘、除等。 (2) 需完成部分三角函数及反三角函数的计算，并且要注意其定义域。   (3) 需完成简单对数函数运算。 (4) 需完成任意数的开根和次方，并且要注意数值

2、要求。 (5) 还需完成对数值的清除及清除全部内容的功能。二、 思路分析单目运算流程图开始计算器界面在X编辑框输入数字选择运算符 是是否符合条件 否输出结果提示错误结束双目运算流程图开始计算器界面在X输入第一个数字是否符合条件 提示错误 否在Y编辑框输入第二个数字 是 提示错误是否符合条件 否 是选择运算符 输出结果结束三、调试分析程序部分输入输出输入输出XY运算符3345+783758*2146783/26123321-19830Sin0.581Sqrt90.5Arcsin30四.程序部分截图1.新建一个MFC工程2.初始化布局3.MFC下个控件布局及配置ID4.程序主界
