计算器设计与实现源代码

计算器主要功能的实现
0~9数字的代码（如下）
void CMy7139Dlg::OnButton0()
{
//TODO: Add your control notification handler code here
m_EDIT=m_EDIT+"0";
SetDlgItemText(IDC_EDIT1,m_EDIT);
}
void CMy7139Dlg::OnButton1()
{
//TODO: Add your control notification handler code here
m_EDIT=m_EDIT+"1";
SetDlgItemText(IDC_EDIT1,m_EDIT);
}
void CMy7139Dlg::OnButton2()
{
//TODO: Add your control notification handler code here
m_EDIT=m_EDIT+"2";
SetDlgItemText(IDC_EDIT1,m_EDIT);
}

void CMy7139Dlg::OnButton9()
{
//TODO: Add your control notification handler code here
m_EDIT=m_EDIT+"9";
SetDlgItemText(IDC_EDIT1,m_EDIT);
}

加减乘除法的实现：
void CMy7139Dlg::OnBtnAdd()
{
// TODO: Add your control notification handler code here
temp=m_EDIT;
op='+';
m_EDIT=_T("");
point=false;
}

void CMy7139Dlg::OnBtnDecrease()
{
// TODO: Add your control notification handler code here
temp=m_EDIT;
op='-';
m_EDIT=_T("");
point=false;
}

void CMy7139Dlg::OnBtnDecrease()
{
// TODO: Add your control notification handler code here
temp=m_EDIT;
op='*';
m_EDIT=_T("");
point=false;
}

void CMy7139Dlg::OnBtnDecrease()
{
// TODO: Add your control notification handler code here
temp=m_EDIT;
op='/';
m_EDIT=_T("");
point=false;
}

次方的实现：
void CMy7139Dlg::OnBtnXy()
{
// TODO: Add your control notification handler code here
po temp=m_EDIT;
op='^';
m_EDIT=_T("");
int=false;
}
三次方的实现（二次方的实现同理）：

{
// TODO: Add your control notification handler code here
char ch2[50];
int squ3;
int squ4;
double temp3;
double temp4;
switch(form)
{
case 'H': squ3=_tcstoul(m_EDIT, 0, 16);
squ4=pow(squ3,3);
m_EDIT.Format("%X",squ4);
SetDlgItemText(IDC_EDIT1,m_EDIT);
break;
case 'D': temp3 = atof((LPCTSTR)m_EDIT);
temp4=pow(temp3,3);
m_EDIT.Format("%f",temp4);
SetDlgItemText(IDC_EDIT1,m_EDIT);
point=true;
break;
case 'O': squ3=_tcstoul(m_EDIT, 0, 8);
squ4=pow(squ3,3);
m_EDIT.Format("%o",squ4);
SetDlgItemText(IDC_EDIT1,m_EDIT);
break;
case 'B': squ3=_tcstoul(m_EDIT, 0, 2);
squ4=pow(squ3,3);

break;
default: return;
}

m_EDIT.Format("%f",sin(si

ntemp * PI/180));
SetDlgItemText(IDC_EDIT1,m_EDIT);
