C++ 虚函数表 vtable

---

本篇文章通过小实验来了解了解虚函数表，测试环境 ubuntu16 gcc 5.4.0

1.测试代码

测试代码中定义了两个类，后面将会查看这两个类的虚函数表

#include <iostream>
using namespace std;

class Object {
   
public:
    Object(){
   
        cout << "Object()" << endl;
    }
    virtual ~Object(){
   
        cout << "~Object()" << endl;
    }
    virtual void print() {
   
        cout << "Object::print()" << endl;
    }
private:
};

class Widget : public Object {
   
public:
    Widget() {
   
        cout << "Widget()" << endl;
    }
    ~Widget() {
   
        cout << "~Widget()" << endl;
    }
    void print() override<
