各位大神求教《带你学C带你飞》【第一季】S1E2课后作业问题
首先拜谢各位大神，谢谢是照着S1E2课后作业敲的，GCC编译时提示错误。环境是Ubuntu 18.04Vim版本8.0 GCC版本7.4
提示如下：
root@wang-virtual-machine:/home/myfiles# gcc s1e2.c -o s1e2.exe
s1e2.c:42:1: error: expected identifier or ‘(’ before ‘{’ token
{
^
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)
{
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 = ".";
printf("计算中...\n");
findAllDirs(path);
printf("目前你总共写了 %ld 行代码！\n\n",total);
return 0;
}
谢谢各位大佬帮忙 第41行 int isCode(const char *filename);
这里多了个分号 superbe 发表于 2019-9-3 15:58

谢谢大哥，谢谢{:9_221:}
敲代码真特码得细心，都是粗心惹的锅。
