    Define * and @ in Objective-C.

    * is used for indicating pointers, because Obj-C is based on C language and C language having pointers. Since all object variables are pointers that's needed for each and every object. and

    @ is used to identify NSString literals. If we will not use @ sign then it will be a C string. @ is a compiler directive which tell the compiler that this string is an Objective-C string. NSString and C strings are different so @ sign is used to differentiate them. but sometimes it relates to code or file constructs like @interface, @protocol, @implementation, and @end.
