example is given in C ++ programming language design. h declares a class, and in the stack. CPP implements the method of this class (including header files of course). When we need to use the Stack class on other pages, we need to reference it to stack. h file, as shown in: Let's take a look at the definition of stack. h: Class Stack{Public:Stack (int s );~ Stack (void ); PRIVATE:Const int max_size;Char

With computer hardware and software knowledge background of the programmer, understand the computer CPU composition and how to manage memory, assembly language is running in the CPU, the compiler language and interpretation of language
Probably all beginners who learn C language, have been said by predecessors, C language is the world's fastest programming language, of course, this is not bragging, and not to belittle other languages, admittedly not C language can write high speed code, but C
