How to create header files in C++-EEWORLD

Collect

Create a header file. (Without parameters)

cpp is linked to the header file through the class name + :: + function name. Note that it must be the class name + ::!
The function code is placed in the corresponding function name under cpp, while the header file only contains the function name, which is only responsible for providing mapping.
animal. cpp
#include "animal.h"
#include
animal::animal()
{
cout<<"hello"< }
void animal::eat ()
{
cout<<"shift"< }

animal.h
//The header file only writes the function name and provides the link address.
#ifndef ANIMAL_H_H
#define ANIMAL_H_H
class animal
{
public:
animal();

void eat();
};
#endif

-------------------------------------------------- ----------------------------------

If you don't create a header file, you have to write such a long code that is not very readable #include

class animal

{

public:

animal()

{

cout<<"animal construct"<

}

~animal()

{

cout<<"construct animal"<

}

virtual void breath()

{

cout<<"bubble2"<

}

void eat(); //Put the main function outside the class

};

class fish:public animal

{

public:

fish()

{

}

~fish()

}

void breath()

{

}

};

void animal::eat() // Function type, which class it belongs to. Put the implementation of a function outside the class.

{

}

void main()

{

}

Why should the P0~P3 ports of the 89C51 microcontroller be set to 1 when inputting?

The P0~P3 ports of the 89C51 microcontroller are not standard bidirectional ports, but quasi-bidirectional ports. You can read this paragraph in conjunction with the structure diagram of port P0 . Writing 1 to the port is writing 1 to the latch. That is to let its port output FF, why, it is like this, write 1 to the

ARM11 S3C6410 Hardware Floating Point (VFP) Implementation

When debugging a code, the code can be compiled successfully. However, it cannot be executed. After searching for a long time, I found that it was a floating point problem. Since 6410 supports hardware floating point, I searched for a long time before I figured out how to use hardware floating point. 1. Select

ARM C/C++ Compiler

The ARM C/C++ compiler can be used in UNIX and Windows/MS-DOS environments. The ARM C++ compiler complies with the international standard for C++ ISO/IEC 14822:1998. The ARM C/C++ compiler can compile C/C++ source code in multiple formats, including ANSI C, EC++, and C++. Table 1 lists the various C/C++ compilers in AR

Pay attention to the data operation exceeding the range in C language

Note: If the calculation formula can be written in one long line, write it separately, as long as the accuracy is guaranteed! ! Writing a long line may affect the accuracy! For example: unsigned long int X; double AD; AD=AD/50.0; X=AD*5000.0000/1023.00; It is best to calculate locally first,
