是编译器迭代的问题吗?
怎么办?
求求了!
程序
#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;
}
