s1e2课中计算代码的程序出现情况
看不太懂,应该怎么改
我的:
#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 countLine(const char *filename);
int isCode(const char *filename);
void findAllDir(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 (!istrcmp(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))
{
findeAllDirs(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("目前共写了%ld行代码!\n\n",total);
return 0;
}
小甲鱼是这样的:
#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;
}

我把你代码中得错误找出来了,在下边,报错信息也提示你函数没有定义准确所以会找不到
- int countLine(const char *filename);
- //应该是这样--》int countLines(const char *filename);
- int isCode(const char *filename);
- void findAllDir(const char *path);
- //应该是这样--》void findAllDirs(const char *path);
- int isCode(const char *filename)
- {
- int length;
- length = strlen(filename);
- //下边这里你写错了:你写的是: if (!istrcmp(filename + (length - 2),"c"))
- if (!strcmp(filename + (length - 2), ".c"))
- {
- return 1;
- }
- else
- {
- return 0;
- }
- }
