直接用string类处理字符串。

AC代码：

#include<iostream>
#include<cstdio>
#include<cstring>

using namespace std;

int main()
{
    int t,k,n,i;
    string s,p;
    scanf("%d",&t);
    k = 0;
    while(t--)
    {
        k++;
        cin>>s;
        n = s.length();
        if(s[n-1]=='u'&&s[n-2]=='s'&&s[n-3]=='e'&&s[n-4]=='d')
        {
            s.erase(n-4,n);  //删掉最后4个字符
            s+="nanodesu";
        }
        else
        {
            s+="nanodesu";
        }
        printf("Case #%d: ",k);
        cout<<s<<endl;
    }

    return 0;
}
