C++创建类与应用

Animal.h 头文件

#ifndef ANIMAL_H_#define ANIMAL_H_#include <string>using std::string;class Animal {public:Animal();Animal(string);virtual ~Animal();void say();string getName();void setName(string);private:string name;};#endif 

 Animal.cpp 实现文件

#include "Animal.h"#include <iostream>using namespace std;Animal::Animal() {}Animal::~Animal() {}Animal::Animal(string name){this->name = name;}void Animal::say(){cout << "my name is " + Animal::getName() << endl;}string Animal::getName(){return this->name;}void Animal::setName(string name){this->name = name;}

Main.cpp 执行文件

#include "Animal.h"int main(int argc, char **argv) {Animal animal ;animal.setName("animal");animal.say();/*使用构造函数*/Animal animal2("animal2");animal2.say();}
