哪的错啊
#include<iostream>
using namespace std;
int main()
{
    char a[100];
    int i=0;
    for(i=0;i<=100;i++)
    {
        while(cin>>a)
        {
            if(a=='\0')
            {
                break;
            }
            else
                i++;
        }
            cout<<i<<endl;
    }
    return 0;
}
