C++根据文件路径获取文件名

#include "stdafx.h"
#include <iostream>
#include <string>
using namespace std;

std::string GetPathOrURLShortName(std::string strFullName);


int _tmain(int argc, _TCHAR* argv[])
{
    std::string strFilePath = "C:/Windows/Dit/test.txt";

    std::string strFileName = GetPathOrURLShortName(strFilePath);

    cout << strFileName << endl;

    system("pause");

    return 0;
}
