Vector容器操作综合实例代码：

#include<iostream>
#include<vector>
#include<algorithm>
#include<string>
using namespace std;
int main()
{
vector<string> sentence;
sentence.reserve(5);
sentence.push_back("Hello,");
sentence.push_back("how");
sentence.push_back("are");
sentence.push_back("you");
sentence.push_back("?");
copy(sentence.begin(),sentence.end(),ostream_iterator<string>(cout," "));
cout<<endl;
cout<<"max_size():"<<sentence.max_size()<<endl;
cout<<"size():"<<sentence.size()<<endl;
swap(sentence[1],sentence[3]);
sentence.insert(find(sentence.begin(),sentence.end(),"?"),"always");
sentence.back()="!";
copy(sentence.begin(),sentence.end(),ostream_iterator<string>(cout," "));
cout<<endl;
cout<<"max_size():"<<sentence.max_size()<<endl;
cout<<"size():"<<sentence.size()<<endl;
cout<<"capacity():"<<sentence.capacity()<<endl;
}

运行结果：
