This is a fairly simple question but I just want to make sure. Do char* c char * c and char *c all mean the same thing or are they different?

Yes, they all mean the same syntactically - however, from a human semantics point of view, they often don't!

For example, one often sees something like this:

1. char *p;

2. *p = ...

Here, in '1', *p declares a pointer to a character.

in '2' *p IS a char.

So, if I said to you what's *p what would you say?

Now consider:

1. char * p;

2. *p = ...

In '1' we now have '*<>p' which at least gives a hint that, as in '2', *p is different, i.e., we use white-space to *help* ourselves and others to note that the two are not the same - in the first notation, *p/*p look the same, but are different, in'2' * p/*p might show those who are less savy that something's not quite the same.
