Question

VC++中怎么将CString与double互相转换！

比如CString的a=“123”，b=“456”，把它们转换成double型，相加后结果再转成CString型！

Answer 1

#include "stdafx.h"
#include "atlstr.h"
int main()
{
CString a="123";
CString b="456";
double k;
k= _wtof(a.GetBuffer(a.GetLength()));
double k1;
k1= _wtof(b.GetBuffer(b.GetLength()));
double sum1=k+k1;
CString sum;
sum.Format(_T("%f"),sum1);
printf("%s",sum);
getchar();
getchar();
return 0;
}

Answer 2

string aa = "123";
string bb = "123";
int cc = atoi(aa.c_str()); //atoi
