求用MFC编写的计算器的源代码，请发到我邮箱heyanhong6688@163.com，非常感谢
在MFC
AppWized(exe)项目下做。界面自己做
1.在对话框的头文件CalculatorDlg.h中添加#includemath.h
2.为CCalculatorDlg类添加成员数据和成员函数
double
number1,number2;
int
NumberState,OperationState;
void
cal();
并在CCalculatorDlg类的构造函数中增加NumberState=1;
3.添加消息按钮afx_msg
void
OnNumberKey(UINT
nID);
afx_msg
void
OnOperationKey(UINT
nID);
4.在CalculatorDlg.cpp文件中BEGIN_MESSAGE_MAP(CMy1Dlg,
CDialog)和END_MESSAGE_MAP()间添加代码
ON_COMMAND_RANGE(IDC_NUMBER1,IDC_NUMBER10,OnNumberKey)
ON_COMMAND_RANGE(IDC_NUMBER11,IDC_NUMBER20,OnOperationKey)
5.为成员函数OnNumberKey和OnOperationKey添加代码
void
CCalculatorDlg::OnNumberKey(UINT
nID)
{
int
n=0;
switch(nID)
{
case
IDC_NUMBER1:n=1;break;
case
IDC_NUMBER2:n=2;break;
case
IDC_NUMBER3:n=3;break;
case
IDC_NUMBER4:n=4;break;
case
IDC_NUMBER5:n=5;break;
case
IDC_NUMBER6:n=6;break;
case
IDC_NUMBER7:n=7;break;
case
IDC_NUMBER8:n=8;break;
case
IDC_NUMBER9:n=9;break;
case
IDC_NUMBER10:n=0;break;
}
if(NumberState==1)
{
m_result=m_result*10+n;
number1=m_result;
UpdateData(FALSE);
//
更新编辑框中的值
}
else
{
m_result=m_result*10+n;
number2=m_result;
UpdateData(FALSE);
}
}
void
CCalculatorDlg::OnOperationKey(UINT
nID)
{
switch(nID)
{
case
IDC_NUMBER13:
//
"/"按钮
OperationState=1;
UpdateData(FALSE);
m_result=0;
NumberState=2;
break;
case
IDC_NUMBER14:
//
"*"按钮
OperationState=2;
UpdateData(FALSE);
m_result=0;
NumberState=2;
break;
case
IDC_NUMBER15:
//
"+"按钮
OperationState=3;
UpdateData(FALSE);
m_result=0;
NumberState=2;
break;
case
IDC_NUMBER16:
//
"-"按钮
OperationState=4;
UpdateData(FALSE);
m_result=0;
NumberState=2;
break;
case
IDC_NUMBER17:
//
"C"按钮，撤消用，不需要可以删除
number1=number2=m_result=0;
UpdateData(FALSE);
NumberState=1;
break;
case
IDC_NUMBER20:
//
"="按钮
cal();
//
调用cal成员函数
break;
}
}
6.为成员函数cal()添加代码
void
CCalculatorDlg::cal()
{
switch(OperationState)
{
case
1:
m_result=(double)number1/number2;
UpdateData(FALSE);
//
更新编辑框中的结果
number1=m_result;
//
把此次的运算结果作为下一次运算的第一个操作数
NumberState=2;
//
下次输入的数作为第二个操作数
break;
case
2:
m_result=number1*number2;
UpdateData(FALSE);
//
更新编辑框中的结果
number1=m_result;
NumberState=2;
break;
case
3:
m_result=number1+number2;
UpdateData(FALSE);
//
更新编辑框中的结果
number1=m_result;
NumberState=2;
break;
case
4:
m_result=number1-number2;
UpdateData(FALSE);
//
更新编辑框中的结果
number1=m_result;
NumberState=2;
break;
}
OperationState=0;
}
注意按钮的ID号要和程序中的ID号相同！！！！要不然会有的按钮点击没反应……
c语言的mfc怎么编程计算器，急用，有详细步骤截图代码。谢谢。帮帮忙。
#include stdio.h
void main(){
int a , b;
char cOperator;
int x;
printf("请输入两个整数的运算式:\n");
scanf("%d%c%d",a,cOperator,b);
if(cOperator=='+')x=(a + b);
else if(cOperator=='-')x=(a - b);
else if(cOperator=='*')x=(a * b);
else if(cOperator=='/')x=(a / b);
else printf("符号输入错误!\n");
printf("%d%c%d",a,cOperator,b);
printf("=%d\n",x);
}
(1)不知道楼主为什么要用"while",但个人认为没有必要.
(2)楼主所有的if语句都存在问题,例如:if(cOperator='+')这句,应改为if(cOperator=='+'),因为C语言中的"="不是代表"等于",而是"赋值".
MFC编写计算器具体步骤 方法 代码，拜托高手急用！
1、首先打开VS2013，新建一个VC++ MFC项目，命名为 gongzi。
2、然后在程序类型中，选择“基于对话框”，点击“完成”按钮。
3、然后在弹出的对话框中，删除原先的Static Text，添加相应的控件到窗体上。
4、接着在应发工资编辑框右击添加变量。 变量名称是 m_editTotal， 变量类型是 double， 类别为 value，点击“完成”。同样扣税费用编辑框右击添加变量。 变量名称是 m_editTax， 变量类型是 double， 类别为 value，应扣税款标签右击添加变量。
5、然后双击“计算应扣税款”进入代码，添加代码。
6、最后点击运行，输入对应的数目，按下按钮，查看执行效果。
