I'm a little confused by the output of the Human readable time slide.  Its a char pointer that does not need to be de-referenced and seems to contain a string which may possibly be an array of chars.  Any extra information on this?  thanks for any extra help.

cout<<"Yes, that's a digit"<<endl;
o/p:Yes, that's a digit

cout<<"Yes, that's a digit"<<endl;

So, does isdigit need a character input? The slides say it takes an integer value. I would be glad if you could clear up my confusion.
