Check if s[0] is equal to '\0'. You might also need to check if s itself is a null pointer, in which case it would not be pointing to the first char of an empty string, but simply be a null pointer.

I forgot to mention i am trying to read by cin>>s...which in fact doesn't allow me to introduce an empty string...what other alternative?
Use a std::string instead of a char*.
