Question

Out of curiosity; why is convention for pointers in C languages like this:


NSString *str = ...


Wouldn’t be more appropriate to write:


NSString* str = ...


because we are defining pointer to NSString? (in Objective-C methods we do have (NSString*)parameter1 convention)

Again – I’m asking out of curiosity and to be able to better understand logic behind this… I’m not trying to reinvent the wheel or start flame war.

Answer 1

If you declare multiple pointer variables in a single declaration, you must write

char *a, *b;

since the declaration

char* a, b;

would declare a as a char pointer, but b as a plain char. IOW, this spacing shows that the asterisk really binds to the name only where it appears.
