类的概念
定义一个类Human，包含Name \ Age 两个属性，构造函数和析构函数，还有一个introduceSelf的方法
Human.h
#ifndef HUMAN_H
#define HUMAN_H
#include <iostream>
#include <string>
using namespace std;
class Human
{
public:
Human();
virtual ~Human();
void setAge(int age);
int getAge();
void setName(string name);
string getName();
void introduceSelf();
protected:
private:
string m_strName;
int m_iAge;
};
#endif // HUMAN_H
Human.cpp
#include "Human.h"
Human::Human()
{
m_iAge = 0;
cout << "Human::Human" << endl;
}
Human::~Human()
{
cout << "Human::~Human" << endl;
}
void Human::setAge(int age)
{
m_iAge = age;
}
int Human::getAge()
{
return m_iAge;
}
void Human::setName(string name)
{
m_strName = name;
}
string Human::getName()
{
return m_strName;
}
void Human::introduceSelf()
{
cout << "m_iAge = " << m_iAge << endl;
cout << "m_strName = " << m_strName << endl;
}
main.cpp
#include "Human.h"
int main(int argc, char** argv)
{
Human p1;
Human p2;
p1.setAge(10);
p1.setName("lilei");
p2.setAge(20);
p2.setName("jim");
p1.introduceSelf();
p2.introduceSelf();
return 0;
}
