STL-去除vector中重复的元素

// Test7.cpp : Defines the entry point for the console application.

#include "stdafx.h"
#include <vector>
#include <string>
#include <algorithm>
int _tmain(int argc, _TCHAR* argv[])
{
	std::vector<std::string> singleValueVector;
	singleValueVector.push_back("acid");
	singleValueVector.push_back("acre");
	singleValueVector.push_back("also");
	singleValueVector.push_back("ache");
	singleValueVector.push_back("ache");
	singleValueVector.push_back("radio");
	singleValueVector.push_back("able");
	singleValueVector.push_back("ache");
	singleValueVector.push_back("ache");
	singleValueVector.push_back("acid");
	singleValueVector.push_back("acre");
	singleValueVector.push_back("auto");
	singleValueVector.push_back("away");
	singleValueVector.push_back("also");
	singleValueVector.push_back("ache");
	singleValueVector.push_back("ache");
	singleValueVector.push_back("acid");
	singleValueVector.push_back("acre");
	singleValueVector.push_back("also");
	sort(singleValueVector.begin(), singleValueVector.end());//sort the vector
	singleValueVector.erase( unique( singleValueVector.begin(), singleValueVector.end() ), singleValueVector.end());//Remove duplicate vector values
	return 0;
}

debug下处理后的vector的值：
singleValueVector[8]("able","ache","acid","acre","also","auto","away","radio")
