怎么在builder中使用vector

[opacity]

谁能给我一个在builder中使用vector的小例子？谢谢~~

#include <fstream>
#include <iostream>
#include <algorithm>
#include <string>
#include <iterator>
#include <vector>
using namespace std;

1. int i=0 ;
vector<int> v ;
for(i=0;i<10;i++)
{
v.push_back(i);//把元素一个一个存入到vector中
}
ShowMessage(v[8]);

2.安字母顺序
ifstream inFile("books.txt");
vector<string> svec;
copy(istream_iterator<string>(inFile), istream_iterator<string>(), back_inserter(svec));
sort(svec.begin(), svec.end());
ofstream outFile("books_r.txt");
copy(svec.begin(), svec.end(), ostream_iterator<string>(outFile,"\n"));
inFile.close();
outFile.close();

3.安数字大小顺序
ifstream inFile("books.txt");
vector<int> svec;
copy(istream_iterator<int>(inFile), istream_iterator<int>(), back_inserter(svec));
sort(svec.begin(), svec.end());
ofstream outFile("books_i.txt");// Copy vector to cout
copy(svec.begin(), svec.end(), ostream_iterator<int>(outFile,"\n"));
inFile.close();
outFile.close();

建一个记事本books.txt，里面输入一些数字如：
5454
21
354
3658
84
9242
