参考代码:

#include<iostream>
using namespace std;
#include<string>
int main()
{
    int i,j=2;
    string s1,s2;
    cin>>s1>>s2;
    while(j>=0)
    {
        if(s1.compare("dotcpp")==0&&s2.compare("123456")==0)
        {
        cout<<"Successful landing!";
        break;
        }
        else
        {
            if(j!=0)
            cout<<"Landing failure! There's another "<<j<<" chance!"<<endl;
            cin>>s1>>s2;
            j--;
            if(j==0)
            cout<<"Account freeze!";
        }
    }
    return 0;
