[C++知识库]c++ 面向对象

#include<iostream>
#include <ctime>
#include<string>
 
using namespace std;

class People{
public:
	string name;
	int age;
	string getName();
	int getAge();
	void setName(string name);
	void setAge(int age);
};

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

void People::setAge(int ages){
	age = ages;
}

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

void People::setName(string names){
	name = names;
}

void main()
{
	People peo;
	peo.setAge(10);
	peo.setName("123");
	cout << peo.getName()<<endl;
	cout << peo.getAge()<<endl;
}

在使用字符串string 时，须加上头文件 否则会报错

#include<string>

 error C2679: binary '<<' : no operator defined which takes a right-hand operand of type 'class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >' (or 
there is no acceptable conversion)
