用C语言编写统计指定目录中*.C,*CPP文件代码行数
用C语言编写
统计指定目录中包括子目录 *.C,*.CPP,*.h文件代码行数
不知道大家以前编过这样的程序,谢谢帮助

应你要求，使用findfirstfile
c++ （要c的话，改改就好了）
#include "windows.h "
#include "stdio.h "
#include "iostream "
#include "string "
#include "fstream "
using namespace std;
#define TestDir "D:\\test_line\\* "

int lines; // 行熟
int c_mun; // c / cpp 文件个数
};
void calc_lines(const char strPath[], Info& info)
{
string str;
ifstream file(strPath);
while (!file.fail())
{
getline(file, str);
info.lines++;
}
}
void find_match_file(const char strPath[], Info& info)
{
WIN32_FIND_DATAA wfd;
HANDLE hHandle = FindFirstFile(strPath, &wfd);
if (hHandle == INVALID_HANDLE_VALUE)
return;
while (FindNextFile(hHandle, &wfd))
{
if (wfd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
{

calc_lines(wfd.cFileName, info);
}
}
else if (len > 2)
{

FindClose(hHandle);
