第七站:C++面向对象训练

1:介绍

创建两个类,一个boy类,一个girl类,实现对两个类的数据输入,并通过main函数,对两个类的成员进行比较匹配

涉及:

vector容器,面向对象,const关键字,? stringstream(sstream.h)?

stringstream用法

stringstream ret;//可以将写入的数据转换成字符串
ret << "姓名:" << name << "-年龄-" << age << "-颜值-" <<yanZhi<< endl;
return ret.str();

vector是一个顺序容器(长度自动分配),类型自适应

用法:<vector>头文件

一维:vector<数据类型> 容器名? ?注:类是一种特殊的数据类型,也能放

二维:vector<vector<数据类型>> 容器名

例子:详细例子可以参考主页天天酷跑的游戏

二维的
vector<vector<IMAGE>> ObstractIMG;//image ObstractIMG[][]

IMAGE imgPillar[pillarNum];
一维的
vector<IMAGE> imgHArray;
sprintf_s(name,sizeof(name) ,"res/h1.png");
loadimage(&imgPillar[0], name, 63, 260, true);
通过push.back先往一维里放
imgHArray.push_back(imgPillar[0]);
然后再将一维的放进二维的
ObstractIMG.push_back(imgHArray);

分布:

每一个类都有.h声明头文件和.cpp实现文件

2:girl类

.h

#pragma once
#include <iostream>
#include <string>
#include <vector>

using namespace std;
class Boy;
class Girl{
public:
	Girl();
	~Girl();
	Girl( string name,  int age,  int yanZhi);
	string getName()const;
	int getAge() const;
	int getYanZhi()const;
	bool satisfied(const Boy& boy) const;
	string describe()const;
	static void inputGirls(vector<Girl>& girl);

private:
	string name;
	int age;
	int yanZhi;
};

.cpp

?

#include "Girl.h"
#include <sstream>
#include "Boy.h"
//设置一个颜值系数

#define YANZHI_FACTOR 100
Girl::Girl() {
	name = "";
	age = 0;
	yanZhi = 0;
}
Girl::~Girl() {

}

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

string Girl::getName() const {
	return name;
}
int Girl::getAge() const {
	return age;
}
int Girl::getYanZhi() const {
	return yanZhi;
}
bool Girl::satisfied(const Boy& b) const{
	if (b.getSalary() >= yanZhi * YANZHI_FACTOR) {
		return true;
	}
	return false;
}

string Girl::describe() const {
	stringstream ret;//可以将写入的数据转换成字符串
	ret << "姓名:" << name << "-年龄-" << age << "-颜值-" <<yanZhi<< endl;
	return ret.str();
}

void Girl::inputGirls(vector<Girl>& girl){
	string name;
	int age;
	int yanZhi1;
	int n = 1;
	while (n) {
		cout << "请输入女方第" << n << "个人的年龄:";
		cin >> age;
		if (age == 0) {
			break;
		}
		cout << "请输入第" << n << "个人的姓名:";
		cin >> name;
	
		cout << "请输入第" << n << "个人的颜值:";
		cin >> yanZhi1;
		n++;
		girl.push_back(Girl(name, age, yanZhi1));
	}
}

3:boy类

.h

#pragma once
#include <iostream>
#include <string>
#include <vector>

using namespace std;
class Girl;
class Boy{
public :
	Boy();
	~Boy();
	Boy(string name, int age, int salary);
	Boy(const Boy& other);
	string getName() const;
	int getAge() const;
	int getSalary() const;
	bool satisfied(const Girl& girl) const;
	string describe() const;
	static void inputBoys(vector<Boy> &boy);

private:
	string name;
	int age;
	int salary;
};

.cpp

?

#include "Boy.h"
#include <sstream>
#include "Girl.h"

//定义一个薪资参数
#define SALARY_FACTOR 0.006

Boy::Boy() {
	name = " ";
	age = 0;
	salary = 0;
}
Boy::Boy(string name, int age, int salary){
	this->name = name;
	this->age = age;
	this->salary = salary;
}
Boy::Boy(const Boy& other){
	salary = other.salary;
	name = other.name;
	age = other.age;
}
Boy::~Boy() {

}

string Boy::getName()const {
	return name;
}

int Boy::getAge() const{
	return age;
}
int Boy::getSalary()const {
	return salary;
}
bool Boy::satisfied(const Girl& girl) const{
	if (girl.getYanZhi() >= salary * SALARY_FACTOR) {
		return true;
	}
	return false;
}
string Boy::describe() const {
	stringstream ret;//可以将写入的数据转换成字符串
	ret << "姓名:" << name << "-年龄-" << age << "-薪资-" <<salary<< endl;
	return ret.str();
}

void Boy::inputBoys(vector<Boy> &boy){
	string name;
	int age;
	int salary;
	int n = 1;
	while (n){
		cout << "请输入第" << n << "个人的年龄:";
		cin >> age;
		if (age == 0) {
			break;
		}
		cout << "请输入第"<<n<<"个人的姓名:";
		cin >> name;
		cout << "请输入第" << n << "个人的薪资:";
		cin >> salary;
		n++;
		boy.push_back(Boy(name, age, salary));
	}
}

4:main主函数

?

#include "Boy.h"
#include "Girl.h"
#include <iostream>
#include <vector>
using namespace std;
void autoCompere(vector<Boy>& boys, vector<Girl> girls) {
	for (int i = 0; i < boys.size(); i++){
		for (int j = 0; j < girls.size(); j++) {
			if (boys[i].satisfied(girls[j]) && girls[j].satisfied(boys[i])) {
				cout << boys[i].describe() << "\n---匹配成功---\n" << girls[j].describe()<<endl;
			}
			else {
				cout << "匹配失败!!" << endl;
			}
			cout << endl;
		}
	}
}

int main(void) {
	vector<Boy> boys;
	vector<Girl> girls;
	Boy::inputBoys(boys);
	Girl::inputGirls(girls);
	cout << "\n\n----匹配中----" << endl;
	autoCompere(boys, girls);
	return 0;
}
