如何交换对象的数组？ [英] How do I swap array of the object?

问题描述

#include< iostream>

#include< cstdlib>

#include< fstream>

using namespace std;





int Qclothes，Qshoes，Qtoiletries，Qgadget，temp;

class MySuitcase

{

public：

int quantity; //数据成员声明

char颜色;

双倍重量;

char sizeA; //衣服的大小s，m，l，xl

int size2; //鞋子大小（4-10）

int i，j;



MySuitcase（）//没有参数的构造函数

{

char white，s;

quantity = 0;

weight = 0;

color = white;

sizeA = s;

size2 = 4;

}



double total_weight（双v，双w，双x，双y，双z）

{

double total_weight;

total_weight = v + w + x + y + z; //用于计算物品总重量的功能

返回total_weight;

}





};

void printArray（int arr []，int size）{

for（int p = 0; p< size; p ++）{

cout<< arr [p]<< '';

}

cout<<结束;

}



void swap_item（int MySuitcase []，int& i，int& j）

{int temp = 0;

temp = MySuitcase [i];

MySuitcase [i] = MySuitcase [j];

MySuitcase [j] = temp;

}

int main（）//主要功能

{

MySuitcase [4] = {Qtoiletries，Qclothes，Qshoes，Qgadget};

int a，b，c，d，press; //数量

双v，w，x，y，z，t;

int printArray; //重量



cout<<请输入您要带入行李箱的物品：<< endl;

cout<<=========盥洗用品=========<< endl; //对象1

cout<<洗漱用品的数量：<<\t; //属性

cout<<您的数量：<<\t<< a<< ; endl;

cout<<\ n;

cout<<你的洗漱用品的重量是多少（公斤）：<< ;\t;

cin>> v;

cout<<你的体重：<<\t<< ; v<<kg<< endl;



cout<<\ n;

cout< <=======礼服=======：<< endl; //对象2

cout<<正式服装的数量：<<\t; //属性

cin>> b;

cout<<\ n;

cout<<什么是正式服装的重量（公斤）：<<\t;

cin>> w;

cout<<你的重量：<<\t<<<<<kg<< endl;



cout<< \ n;

cout<<=======小工具=======<< endl; //对象3

cout<<你带多少小工具：<<\t; //属性

cin>> c;

cout<<您的小工具数量为：<<\t<< c< ;< endl;

cout<<\ n;

cout<<你的小工具重量是多少（公斤）：<< ;\t;

cin>> x;

cout<<你的体重：<<\ t<< ; x<<kg<< endl;



cout<<\ n;



cout<<========鞋子=========<< endl; //对象4

cout<<鞋子的数量：<<\t; //属性

cin>> d;

cout<<您的数量：<<\t<< d<< ; endl;

cout<<\ n;

cout<<鞋子的重量是多少（公斤）：<< ;\t;

cin>> y;

cout<<你的体重：<<\t<< ; y<<kg<< endl;



cout<<\ n;



cout<<行李箱中的总重量为：<<\t<< MySuitcase（）。total_weight（v，w，x，y，z）< ;<kg<< endl;

//所有商品的总重量

cout<<\ n;

if（MySuitcase（）。total_weight（v，w，x，y，z）< = 30）// if-else语句（选择结构）

{//说明是否用户超过30公斤

cout<<你没有超过行李箱的最高限额<< endl;

}

其他

{

cout<<你的行李箱超过了最大重量！<< endl;

}



cout<< 请输入你要交换的东西：;





cout<< 原始数组是：\t;

printArray（arr，4）;



swap_item（arr，0,1） ;

cout<< 交换的数组是：\ t;

printArray（arr，4）;









system（PAUSE）;

返回0;
