在完成 S1E2课后作业的时候出现了如下问题……不知道怎么回事
呃 抄写的代码如下
- #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)
- {
- Istat(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;
- }
复制代码
- lstat(entry->d_name,&statbuf);
