C++编程思想(卷二)：设计模式：模板方法模式

#include <iostream>
using namespace std;
class ApplicationFramework {
protected:
virtual void customize1() = 0;
virtual void customize2() = 0;
public:
void templateMethod() {
for(int i = 0; i < 5; i++) {
customize1();
customize2();
}
}
};
// Create a new "application":
class MyApp : public ApplicationFramework {
protected:
void customize1() { cout << "Hello "; }
void customize2() { cout << "World!" << endl; }
};
int main() {
MyApp app;
app.templateMethod();
}
