RT
cout 25
cin 2 5

应该是如下:
RT
cin 25
cout 2 5

#include <iostream>
using namespace std;
void main()
{
    int n;
    cout<<\"输入一个整数n,n<9999:\";
    cin>>n;
    char buf[5]={0};
    itoa(n,buf,10);
    for(int i=0;i<strlen(buf);i++)
        cout<<buf[i]<<\"  \";
    cout<<endl;
}

谢谢!

string nbr;
cin >> nbr
for (int i = 0;i < nbr.size();++i)
cout << nbr[i] << " ";
cout << endl;
