C++基础

Person.h

#include<string>

using namespace std;

class Person{
    private:int age;
    private:string name;

    public:Person(int age, string name);
    public:int getAge();
    public:string getName();
};

Person.cpp

#include<iostream>
#include<string>
#include"Person.h"

using namespace std;

int Person::getAge(){
	return age;	
}

string Person::getName(){
	return name;
}

Person::Person(int age, string name){
	this->age = age;
	this->name = name;
}

main.cpp

#include<iostream>
#include<string>

#include"Person.h"

using namespace std;

int main(){
    for(int i=0; i<10; i++){
        cout << i << "\n" ;
    }


    Person p1 = Person(10,"aaaaa");
    Person *p2 = new Person(20,"bbbbbb");

    cout << "p1 Name:" << p1.getName() << "\n";
    cout << "p2 Name:" << p2->getName() << "\n";

    delete p2;
}

Makefile

edit:Person.h Person.cpp main.cpp
	g++ Person.cpp main.cpp -o main

分步写Makefile

main:Person.o main.o
	g++ -o main main.o Person.o
Person.o:Person.h Person.cpp
	g++ -c Person.cpp
main.o:main.cpp
	g++ -c main.cpp
clean:
	rm *.o
	rm main

利用ar将.o文件创建为.a文件

ar cr libperson.a Person.o

最好是lib开头，否则有可能找不到

编译

g++ main.cpp -o main -L. -lperson
