But wouldn't that imply you didn't need to use the * when referencing 
the actual value?

For example, if you do this:

char *p;
char c;

The correct way to get the character it's pointing to dereference like this:

c=*p;

If the type was char* (not char)

Wouldn't that imply I wouldn't need the * to dereference the pointer?
