cin的问题
请问(A)处的cin代表什么意思啊int main()
{
using namespace std;
char input[Arsize];
char next;
cout<<"enter a line: \n";
cin.get(input,Arsize);
while(cin) (A)
{
cin.get(next);
while(next!='\n')
cin.get(next);
strcount(input);
cout<<"enter next line(empty line to quit): \n";
cin.get(input,Arsize);
}
cout<<"Bye\n";
return 0;
}
