I’m a java programmer and learning
Obj – C function parameters
When I saw the function declaration
- (void) fraction: (int) n over:(int) n2;
and
- (void) fraction: (int) n :(int) n2;
What’s difference between them? and when should i use between them?
The first method’s name is
fraction:over:.The second method’s name is
fraction::.Obviously, the first name is clearer. Unnamed arguments are valid but not very self-documenting. I personally never use the 2nd form.
