把你的代码发出来吧,这样很难看的出所有的问题
#include <stdio.h>
#include <unistd.h>
#include <dirent.h>
#include <string.h>
#include <stdlib.h>
#include <sys/stat.h>
#define MAX 256
long total;
int countLines( const char *filename);
int isCode( const char *filename);
void findAllDirs( 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;
}
int isCode( const char *filename)
{
int length;
length = strlen( filename);
if(!strcmp(filename + (length - 2),".c"))
{
return 1;
}
else
{
return 0;
}
}
void findAllDirs(const char *path)
{
DIR *dp;
struct dirent *entry;
struct stat statbuf;
if(( dp = opendir(path)) == NULL )
{
fprintf(stderr,"The path %s is wrong!\n",path);
return;
}
chdir(path);
while((entry = readdir(dp)) != NULL)
{
lstat(entry->d_name,&statbuf);
if(!strcmp(".",entry->d_name) || !strcmp("..",entry->d_name))continue;
if(S_ISDIR(statbuf.st_mode))
{
findAllDirs(entry->d_name);
}
else
{
if(isCode(entry->d_name))
{
total += countLines(entry-d_name);
}
}
}
chdir("..");
closedir(dp);
}
int main ()
{
char path[MAX] = ".";
printf("计算中...\n");
findAllDirs(path);
printf("目前你总共写了%ld行代码!\n\n", total);
return 0;
}
