Question

c++将整数转字符串

如将整数123变成string类型“123”，谢谢

Answer 1

#include <iostream>
#include <string>
using namespace std;

int main () {

char str[32];
int num = 123;

itoa(num,str,10);//把num以十进制存到str中
cout<<str;
return 0;
}

追问

能用string str吗

追答

好像不能直接转string
用强制转换
string s2;
s2=(string)str;

Answer 2

CString csTemp;
int i = 123;
csTemp.Format("%d", i);
string strTemp = csTemp.GetBuffer(0);
