VC求一组数的最大值最小值总和以及平均值

第一步：新建对话框应用程序

第二步：添加控件相关变量

CButton	m_calculate;
double	m_score_1;
double	m_score_10;
double	m_score_2;
double	m_score_3;
double	m_score_4;
double	m_score_5;
double	m_score_6;
double	m_score_7;
double	m_score_8;
double	m_score_9;
CString	m_average;
CString	m_max;
CString	m_min;
CString	m_sum;

void CMax_minDlg::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
//{{AFX_DATA_MAP(CMax_minDlg)
DDX_Control(pDX, IDC_BUTTON1, m_calculate);
DDX_Text(pDX, IDC_EDIT1, m_score_1);
DDX_Text(pDX, IDC_EDIT10, m_score_10);
DDX_Text(pDX, IDC_EDIT2, m_score_2);
DDX_Text(pDX, IDC_EDIT3, m_score_3);
DDX_Text(pDX, IDC_EDIT4, m_score_4);
DDX_Text(pDX, IDC_EDIT5, m_score_5);
DDX_Text(pDX, IDC_EDIT6, m_score_6);
DDX_Text(pDX, IDC_EDIT7, m_score_7);
DDX_Text(pDX, IDC_EDIT8, m_score_8);
DDX_Text(pDX, IDC_EDIT9, m_score_9);
DDX_Text(pDX, IDC_STATIC_average, m_average);
DDX_Text(pDX, IDC_STATIC_max, m_max);
DDX_Text(pDX, IDC_STATIC_min, m_min);
DDX_Text(pDX, IDC_STATIC_sum, m_sum);
//}}AFX_DATA_MAP
}

第三步：处理数据

void CMax_minDlg::OnButton1()
{
UpdateData(TRUE);
double array[10];
array[0]=m_score_1;
array[1]=m_score_2;
array[2]=m_score_3;
array[3]=m_score_4;
array[4]=m_score_5;
array[5]=m_score_6;
array[6]=m_score_7;
array[7]=m_score_8;
array[8]=m_score_9;
array[9]=m_score_10;
double max=0;
double min=0;
double sum=0;
double average=0;
int index_max = 0;
int index_min = 0;
for(int i=0; i<10; i++)
{
if(array[i] >= array[index_max])
{
index_max=i;
}

if(array[i] <= array[index_min])
{
index_min=i;
}

sum = sum + array[i];
}

max=array[index_max];
min=array[index_min];

sum = sum - max - min;
average = sum/8;

CString str;

str.Format("%f",max);
m_max = str;

str.Format("%f",min);
m_min = str;

str.Format("%f",sum);
m_sum = str;

str.Format("%f",average);
m_average = str;

UpdateData(FALSE);
}

第四步：运行效果
