这个代码运行显示总写了0行代码看作业答案是显示不是0行

#include<io.h>
#include<direct.h>
#include<stdio.h>
#include<stdlib.h>
#include<string.h>

#define MAX    256

long total;

int countlines(const char *filename);
void findAllCodes(const char *path);
void findALLFiles(const char *path);

int countLines(const char *filename)
{
FILE *fp;
int count = 0;
int temp;

if ((fp=fopen(filename,"r"))==NULL)
{
fprintf(stderr,"Can not open the file:%s\n",filename);
return 0;

}

while ((temp = fgetc(fp)) != EOF)
{
if(temp=='\n')
{
count++;

}
}
fclose(fp);

return count;

}

void findALLCodes(const char *path)
{
struct _finddata_t fa;
long handle;
char thePath[MAX], target[MAX];

strcpy(thePath,path);
if((handle=_findfirst(strcat(thePath,"/*.c"),&fa))!=-1l)
{
do
{
      sprintf(target,"%s%s",path,fa.name);
   total+=countLines(target);

   }while(_findnext(handle,&fa)==0);

}

   _findclose(handle);

}

void findALLDirs(const char *path)
{

struct _finddata_t fa;
long handle;
char thePath[MAX];

strcpy(thePath, path);
if((handle= _findfirst(strcat(thePath,"/*"),&fa)) == -1L)
{
fprintf(stderr,"The path %s is wrong!\n",path);
return;
}

do
{
if(!strcmp(fa.name,".")||!strcmp(fa.name,".."))
         continue;
if(fa.attrib== _A_SUBDIR)
{
      sprintf(thePath,"%s%s", path, fa.name);
findALLCodes(thePath);
findALLDirs(thePath);

}
}while(_findnext(handle,&fa)==0);

_findclose(handle);

}

int main()
{
char path[MAX]=".";

printf("计算中...\n");

findALLCodes(path);
findALLDirs(path);

printf("目录你总写了%ld行代码！\n\n",total);
system("pause");

return 0;
}

这只能识别 .c 文件，你看哈你的路径下有没有 .c 文件呢，我能显示代码行数啊
