Refer to the answer 3：
``#include <iostream>using namespace std;int main(){    int y = 0, n = 0, i = 0;    while(1)    {        int xm;        int num = rand() % 100 + 1;        cout << " Please input ：";        cin >> xm;        if(xm == num)        {            y++;            cout << " Xiao Ming guessed right ." << endl;        }        else        {            n++;            cout << " Xiao Ming guessed wrong ." << endl;        }        if(y >= 3)        {            cout << " Xiao Ming wins ." << endl;            break;        }        if(n >= 3)        {            cout << " The computer wins ." << endl;            break;        }    }    return 0;}``
