Use code and UML diagrams to resolve the design pattern of the bridge pattern in depth analysis

The bridging pattern is the separation of independence and implementation.
Different manufacturers make different products... The product and the manufacturer have this combination relationship.

In the code

//Bridge.cpp: defines the entry point for the console application.
   
#include "stdafx.h"
#include <iostream>
using namespace std;
class Product
{
public:
 Product(){}
 virtual ~Product(){}

 virtual void make()=0;
 virtual void sell()=0;
};
class ProductA:public Product
{
public:
 ProductA(){}
 virtual ~ProductA(){}
 virtual void make()
 {
  cout<<"ProductA:make()"<<endl;
 }
 virtual void sell()
 {
  cout<<"ProductA:sell()"<<endl;
 }
};
class ProductB:public Product
{
public:
 ProductB(){}
 virtual ~ProductB(){}
 virtual void make()
 {
  cout<<"ProductB:make()"<<endl;
 }
 virtual void sell()
 {
  cout<<"ProductB:sell()"<<endl;
 }
};
class Corp
{
public:
 Corp(Product* pro)
  :m_product(pro)
 {}
 virtual ~Corp()
 {
  delete m_product;
 }

 virtual void process()
 {
  m_product->make();
  m_product->sell();
 }
private:
 Product *m_product;
};
class CorpA:public Corp
{
public:
 CorpA(Product * pro) :Corp(pro){}
 virtual ~CorpA(){}
 virtual void process()
 {
  cout<<"CorpA():process()"<<endl;
  Corp::process();
 }
};
class CorpB:public Corp
{
public:
 CorpB(Product * pro) :Corp(pro){}
 virtual ~CorpB(){}
 virtual void process()
 {
  cout<<"CorpB:process()"<<endl;
  Corp::process();
 }
};
int _tmain(int argc, _TCHAR* argv[])
{
 Product* product;
 product = new ProductA;
 Corp * corp ;
 corp = new CorpA(product);
 corp ->process();
 cout<<"----------"<<endl;
 product= new ProductB;

Production and manufacturers are independent implementation, fully give freedom...
