How to add public class?

本文关键字：添加 何添加      更新时间：2023-10-16

嗨，我是c++的新手（我是一名c#用户，想学习c++）我有一个窗体，上面有一张狗的照片，上面有标签和两个按钮现在我想创建一个公共类"C_dog"，其中包含th-ff:

public name
public weight

和功能：

public static sayname()
{
 //when button1 is clicked
  label1.text="Hi my name is "+name;
}
public static sayweight()
{//when button2 is clicked
  label1.text="I weight "+weight+" pounds";
}

当我点击中的add class时，会提示我创建一个头文件，并且它已经在上预编码了内容cpp'如何声明新的C_dog实例？

/* C_dog.h */
public class C_dog 
{
 public:
     C_dog(std::string name, unsigned int weight);   // example for constructor
     ~C_dog();  // destructor
     // declare all members: weight, name etc.
     std::string m_name;
     unsigned int m_weight;
     void sayname();
     void sayweight();
}
/* C_dog.cpp */
#include "C_dog.h"
C_dog::C_dog(std::string name, unsigned int weight)   
{
    m_name = name;
    m_weight = weigth;
}
C_dog::~C_dog() 
{
}
C_dog::sayname()
{
   //when button1 is clicked
   label1.text="Hi my name is "+m_name;    // label1 has to be visible globally
}
C_dog::sayweight()
{
    //when button2 is clicked
    label1.text="I weight "+m_weight+" pounds"; // label1 has to be visible globally
}
/* get a new instance */
C_dog * charlie = new C_dog("charlie", 40);  // this is your new C_dog
/* if not needed any more, don't forget to send him to heaven: */
delete charlie ;
charlie = nullptr;
