A string preceded by L indicates that the string is a Unicode string._t is a macro that, if the project uses a Unicode character set (which defines a Unicode macro), automatically precedes the string with L, otherwise the string does not change.

Object-C (hereinafter referred to as OC) has an ID type, which is a dynamic type compared with a static type that is clearly defined. When dynamic types and polymorphism are used (different types have methods of the same name), dynamic binding (the

Const char * is used to define a pointer to a constant string, usually in the form: Const char * PTR = "hello "; However, many careless friends may not notice the following definition: Const char * ptr2 = "hello "; PTR and ptr2 point to the same
