what does this pointer syntax in C mean?

I came across to a question from one of my friend.

What is the difference between these?

* char ptr
char * ptr

The first declaration * char ptr is not valid C syntax, so that is why you are getting a compile-time error. The second declaration char * ptr is valid C syntax, because the type is listed first followed by the pointer '*' symbol and the variable name.

This is an error:

* char ptr;

This declares ptr as a variable of type pointer-to-char:

char * ptr;

The first line, * char ptr;, is not valid.

The second line, char * ptr; declares a variable of type pointer to char.
