How do you define a class in Objective-c? We can use the following format to represent:[CPP]View Plaincopy @interface Class Name: Parent class Name { variable definition; } method definition; @end; An example is given below:[CPP]View Plaincopy @interface Person:nsobject { nsstring* name; int age; } -(nsstring*) name; -(int) age; -(void) SetNam

declares that there is something associated with this name, and that it is of this type, tells the compiler I want to use it, and expects it to be defined in a certain place. A definition definition is the provision of all necessary information (memory size) so that it can create an entire entity. We must understand that once a definition is declared, a function,

C ++ Reading Notes-class definition (One word and one word on the keyboard !!!) 1. Class Definition syntax The class definition starts with the keyword class.

1. Definition of variable: the definition of a variable is used to allocate storage space for a variable, and you can also specify an initial value for the variable. In a program, variables have and have only one definition.2. Declaration of variables: used to indicate to the program the type and name of the variable. A variable can be declared multiple times in

Solo windLinks: C Language macro definitions (2)1. How do I distinguish between macro names and macro strings in a macro definition? What should be noted for macros with parameters?In the macro definition, the macro name and macro string are distinguished by a "space", in which a space can have a significant effect on the result of the extension. When the compiler processes the macro

Introduction to preprocessing Directives1.C language before compiling the source program, some special pre-processing instructions (such as the previous use of the # include directive) to produce a new source program (this process is called the compilation preprocessing), and then the usual compilation2. In order to differentiate between preprocessing directives and generic C statements, all preprocessor directives begin with the sign "#" and end without semicolons3. A preprocessing instruction

0. PrefaceFrom the beginning of learning C language began to contact Makefile, consulted a lot of makefile information but always feel no real master makefile, if you write a makefile always feel very laborious. So deliberately using the blog to summarize the relevant knowledge of makefile, through examples to illustrate the specific use of makefile. The example says that makefile roughly divides into 4 parts 1. Only a single C file 2. Contains multiple C files 3. Need to include header file pa
