erwin_diow:
when I build the code as following:

--- Code: ---#include <iostream>

using namespace std;

int main()
{
    cout << "请输入一个大于1的整数：" << endl;
    int x;
    cin>>x;
    if(x>1 || x<<99)
        cout<<"x大于1或小于100\n";
    else
        cout<<"x大于或者等于100\n";
    return 0;
}

--- End code ---
there is a warning
