模板模式
class Resume
{
protected: //保护成员
virtual void SetPersonalInfo() {}
virtual void SetEducation() {}
virtual void SetWorkExp() {}
public:
void FillResume()
{
SetPersonalInfo();
SetEducation();
SetWorkExp();

};

建造者模式
class Builder
{
public:
virtual void BuildHead() {}
virtual void BuildBody() {}
virtual void BuildLeftArm(){}
virtual void BuildRightArm() {}
virtual void BuildLeftLeg() {}
virtual void BuildRightLeg() {}
};
//构造瘦人
class ThinBuilder : public Builder
{
public:
void BuildHead() { cout<<"build thin body"<<endl; }
void BuildBody() { cout<<"build thin head"<<endl; }
void BuildLeftArm() { cout<<"build thin leftarm"<<endl; }
void BuildRightArm() { cout<<"build thin rightarm"<<endl; }
void BuildLeftLeg() { cout<<"build thin leftleg"<<endl; }
void BuildRightLeg() { cout<<"build thin rightleg"<<endl; }
};
//构造胖人
class FatBuilder : public Builder
{
public:
void BuildHead() { cout<<"build fat body"<<endl; }
void BuildBody() { cout<<"build fat head"<<endl; }
void BuildLeftArm() { cout<<"build fat leftarm"<<endl; }
void BuildRightArm() { cout<<"build fat rightarm"<<endl; }
void BuildLeftLeg() { cout<<"build fat leftleg"<<endl; }
void BuildRightLeg() { cout<<"build fat rightleg"<<endl; }
};
//构造的指挥官
class Director
{
private:
Builder *m_pBuilder;
public:
Director(Builder *builder) { m_pBuilder = builder; }
void Create(){
m_pBuilder->BuildHead();
m_pBuilder->BuildBody();
m_pBuilder->BuildLeftArm();
m_pBuilder->BuildRightArm();
m_pBuilder->BuildLeftLeg();
m_pBuilder->BuildRightLeg();
}
int main()
{
FatBuilder thin;
Director director(&thin);
director.Create();
return 0;
}
模板模式跟建造者模式的区别：
模板模式由父类实现调用过程，实现细节在子类中区分；成员函数(protected)
建造者模式父类提供接口，子类负责实现；具体实现流程由建造者类通过接口实现；
