获取程序所在目录&列举目录下文件和文件夹--C++实现

话不多说, 直接上代码

CommonFunc.h

#pragma once
#include <direct.h>
using namespace std;

//枚举指定路径下文件，c++方法
void listFiles(char* dir, vector<char*>& vecSzFilename);
//枚举指定路径下文件夹，c++方法
void listDir(char* dir, vector<char*>& vecSzDir);
//获取程序所在文件夹，c++方法
int getWorkDir(char* szProgramPath);

CommonFunc.cpp文件

#include "CommonFunc.h"
//获取当前程序绝对路径
int getWorkDir(char* szProgramPath)
{
	char szPath[_MAX_PATH] = { 0 };
	char szDrive[_MAX_DRIVE] = { 0 };

	char szExt[_MAX_EXT] = { 0 };

	GetModuleFileNameA(NULL, szPath, sizeof(szPath));
	//ZeroMemory(szProgramPath, strlen(szProgramPath));
	_splitpath_s(szPath, szDrive, szDir, szFname, szExt);
	sprintf_s(szProgramPath, _MAX_PATH, "%s%s", szDrive, szDir);

	return 0;
}
//枚举指定路径下文件名, 保存到vector中
void listFiles(char * dir, vector<char*>& vecSzFilename)
{
	char szDir[_MAX_PATH] = { 0 };
	sprintf_s(szDir, _MAX_PATH, "%s%s", dir, "*.*");			
	intptr_t handle;
	_finddata_t findData;

	handle = _findfirst(szDir, &findData);
