C++: how do I check if the cin buffer is empty?

Question

How do you check to see if the user didn\'t input anything at a cin command and simply pressed enter?

Answer 1

The Simple way >>

{
char X=0; //  ASCII( 0 ) means a NULL value
cin>>X;
if(X==0 || X==10) // ASCII( 10 ) means ENTER
cout<<"User din't enter ANYTHING !! ";
}

But a simple problem is....

cin just won't allow you to move further without entering a character

by character here i mean a DIGIT or alphabet or special symbol , not space, enter null etc

Hope this solves your problem, if it doesn't, I'll be glad to help just let me know.
