1、1. 题目：简单计算器2. 实验目的：模仿日常生活中所用的计算器，自行设计一个简单的计算器程序，实现简单的计算功能。3. 实验主要硬件软件环境：Window 7Visual C+ 6.04. 实验内容：(1) 体系设计：程序是一个简单的计算器，能正确输入数据，能实现加、减、乘、除等算术运算，能进行简单三角运算，运算结果能正确显示，可以清楚数据等。(2) 设计思路：1) 先在Visual C+ 6.0中建立一个MFC工程文件，名为calculator.2) 在对话框中添加适当的编辑框、按钮、静态文件、复选框和单选框3) 设计按钮，并修改其相应的ID与Caption.4) 选择和设置各控件的单击鼠
2、标事件。5) 为编辑框添加double类型的关联变量m_edit1.6) 在calculatorDlg.h中添加math.h头文件，然后添加public成员。7) 打开calculatorDlg.cpp文件，在构造函数中，进行成员初始化和完善各控件的响应函数代码。(3) 程序清单：l 添加的public成员：double tempvalue; /存储中间变量double result; /存储显示结果的值int sort; /判断后面是何种运算：1.加法 2.减法 3.乘法 4.除法int append; /判断后面是否添加数字l 成员初始化：CCalculatorDlg:CCalculato
