多文件组织项目Student类

Student.h

#include <string>
using namespace std;

class Student
{
private:
 string user_name;
 string pass_word;

public:
 Student(string user_name, string pass_word);

 string get_user_name();
 string get_pass_word();
 void set_user_name(string user_name);
 void set_pass_word(string pass_word);

 void display();
};

 

Student.cpp

#include <string>
#include <iostream>
#include "Student.h"
using namespace std;

Student::Student (string user_name, string pass_word)
{
 this->user_name = user_name;
 this->pass_word = pass_word;
}

string Student::get_user_name()
{
    return this->user_name;
}

string Student::get_pass_word()
{
 return this->pass_word;
}

void Student::set_user_name(string user_name)
{
 this->user_name  = user_name;
}

void Student::set_pass_word(string pass_word)
{
 this->pass_word = pass_word;
}

void Student::display()
{
 cout << "user_name: " << this->user_name << endl;
 cout << "pass_word: " << this->pass_word << endl;
}

 

Main.cpp

#include <iostream>
#include <string>
#include "Student.h"
using namespace std;

int main()
{
 Student student("xiaoming", "123");
 student.display();
 student.set_pass_word("456");
 cout << student.get_pass_word() << endl;

 return 0;
}

 

运行结果：

user_name: xiaoming
pass_word: 123
456

作此项目之前的准备：

画类图：

类图

Student

string user_name string pass_word

student (string user_name,string pass_word)

string get_user_name() string get_pass_word() void set_name_word(string) void set_pass_word(string) void display()

这样可以使编码更为简单，不会出错

经验积累：

1.对数据成员赋初值时，所有参数必须与所对应的数据成员名称一致；

2.需要访问数据成员时用this指向；

3.画类图比写代码更为重要；

4.做一个项目最好多文件组织项目，良好的习惯需要逐步养成！！！
