[求助]怎么用ｃ－ｆｒｅｅ编译器输入逻辑或（ｏｒ）操作符？
#include <iostream>
using namespace std;
int main ()
{
char ans;
do
{
cout<<"Hello\n";
cout<<"Do you want another greeting?\n"
<<"Press y for yes, n for no,\n"
<<"and then press return:";
cin>>ans;
}while (ans =='y' －－ ans=='Y');
cout<< "Good-Bye\n";
return 0;
}
－－那里使用逻辑或操作符‖
