can someone clarify this for me:

When there’s more than one argument, the arguments are declared within the method name after the colons. Arguments break the name apart in the declaration, just as in a message. For example:

- (void)setWidth:(float)width height:(float)height;

So in the above:

1. method is for instance variables
2. returns void

3. parameter#1 is a float, named width.

4. parameter#2 is a float,named height.

But why is it hieght:(float)height; and not just:

- (void)setWidth: (float)width (float)height;
