c语言计算当前所打代码行数的程序运行时出现问题

Question

请问这是怎么回事呢？

下附这一完整代码：

#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("目前你总共写了 %ld 行代码！\n\n", total);
        system("pause");

        return 0;
}
