方法一：

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

int main()
{ 
    int n = 65535;
    char t[256];
    string s;
    sprintf(t, "%d", n);
    s=t;
    cout<<s<<endl;
    return 0;
}

方法二：

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

int main()
{ 
    int n = 65535; 
    stringstream ss;
    string s;
    ss<<n;
    ss>>s;
    cout<<s<<endl;
    return 0;
