C++基础 -12- 类的析构函数

———————标准输入输出———————

 

🎈析构用于释放构造函数中初始化的数据成员

 

🎈析构不能重载

 

🎄析构函数格式(图片+代码段)

 

#include "iostream"

using namespace std;

extern "C"
{
#include "string.h"
}

class rlxy
{

public:
    int a;
    rlxy(int a, int b, const char *c)
    {
        this->c = new char[1024];
        strcpy(this->c, c);
        cout << c << endl;
    }
    ~rlxy()
    {
        cout << "xg" << endl;
        delete[] c;
    }

protected:
    int b;

private:
    char *c;
};

int main()
{
    rlxy ss(20, 30, "rlxy");
}
