C++学习，实验五

一，

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

// 函数声明 
void output1(vector<string> &);  
void output2(vector<string> &);  

int main()
{
    vector<string>likes, dislikes; // 创建vector<string>对象likes和dislikes
    
    // 为vector<string>数组对象likes添加元素值 ( favorite book, music, film, paintings,anime,sport,sportsman,etc) 
    
    likes.push_back("favorite book");
    likes.push_back("music");
    likes.push_back("film");
    likes.push_back("sport");
    likes.push_back("sportsman");
    
    
    cout << "-----I like these-----" << endl;
    // 调用子函数输出vector<string>数组对象likes的元素值 
    output1(likes);
    
    
    // 为vector<string>数组对象dislikes添加元素值 
     dislikes.push_back("paintings");
     dislikes.push_back("anime");
     dislikes.push_back("etc");
    cout << "-----I dislike these-----" << endl;
    // 调用子函数输出vector<string>数组对象dislikes的元素值 
    output1(dislikes);
    
    
    // 交换vector<string>对象likes和dislikes的元素值 
    likes.swap(dislikes);
     
    
    cout << "-----I likes these-----" << endl;
    // 调用子函数输出vector<string>数组对象likes的元素值 
    output2(likes);
    
    
    cout << "-----I dislikes these-----" << endl;
    // 调用子函数输出vector<string>数组对象dislikes的元素值 
    output2(dislikes); 
        
                        
    return 0;
}


// 函数实现 
// 以下标方式输出vector<string>数组对象v的元素值  
void output1(vector<string> &v) {
    int i;
    for(i=0;i<v.size();i++)
    cout<<v[i]<<endl;
}

// 函数实现
// 以迭代器方式输出vector<string>数组对象v的元素值 
void output2(vector<string> &v) {
    //使用迭代器访问vector中的元素
    vector<string>::iterator i; 
    for(i= v.begin() ; i<v.end() ; ++i)
    cout<<*i<<endl;
    
}
