string转换double
double value = atof(str.c_str());string转换CString
strtest = strZ.c_str();CString 转换为float,int,double
CStringstrval;
strval= “12.43aa”;
char*pChar1 = strval.GetBuffer(strval.GetLength());
floatfval = atof(pChar1);
doubledval = atof(pChar1);
intival = atoi(pChar1);
strval.ReleaseBuffer();//使用GetBuffer之后要ReleaseBufferfloat,int,double转换为CString

CStringtotal_str[3],pass_str[3],yueld_str[3];
for(int i =0; I < 3; i++)
{
total_str[i].Format(“%d”, total[i]) ;
pass_str[i].Format(“%d”,pass[i]);
yield_str[i].Format(“f%”,yield[i]);
}string 转换为 char*,char[]
