如何将多个数值转成字符串连接到一起？

[疯狂低调]

如何将 int a = 200;
int b = 300;
int c= 400;

转换成 字符串 "200300400" ？

[clhposs]

ostringstream s;
s<<a<<b<<c;

[baihacker]

#include <iostream>
#include <cstring>
using namespace std;
char* AddInt(char* buff, int n)
{
	sprintf(buff + strlen(buff),"%d", n);
	return buff;
}
int main()
{
	int a = 200, b = 300, c = 400;
	char buff[256]={0};
	AddInt(AddInt(AddInt(buff, a), b), c);
	cout << buff << endl;
	return 0;
}

#define BUFFSIZE 100
//...
char output[BUFFSIZE];
sprintf(output,"%d%d%d",a,b,c);

先用itoa（）把数字转为字符
然后在把字符串为CString
然后在用'+'号把几个字符串连起来

支持2楼的标准C++.
