S1E2的课后作业求助(不是出错,是最后呈现的行数不对)
作业地址:https://fishc.com.cn/forum.php?mod=viewthread&tid=66283&extra=page%3D1%26filter%3Dtypeid%26typeid%3D570这是我敲的:
#include<io.h>
#include<direct.h>
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#define MAX 256
long total;
int countLines(const char *filename);
void findAllCodes(const char *path);
void findAllFiles(const char *path);
int countLines(const char *fliename)
{
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;
}
void findAllCodes(const char *path)
{
struct _finddata_t fa;
long handle;
char thePath, target;
strcpy(thePath, path);
if((handle = _findfirst(strcat(thePath, "/*.c"), &fa)) != -1L)
{
do
{
sprintf(target, "%s/%s", path, fa.name);
total += countLines(target);
}while (_findnext(handle, &fa) == 0);
}
_findclose(handle);
}
void findALLDirs(const char *path)
{
struct _finddata_t fa;
long handle;
char thePath;
strcpy(thePath, path);
if((handle = _findfirst(strcat(thePath, "/*"), &fa)) == -1L)
{
fprintf(stderr, "The path %s is wrong!\n",path);
return;
}
do
{
if (!strcmp(fa.name, ".") || !strcmp(fa.name, ".."))
continue;
if( fa.attrib == _A_SUBDIR)
{
sprintf(thePath, "%s/%s", path, fa.name);
findAllCodes(thePath);
findALLDirs(thePath);
}
}while (_findnext(handle, &fa) == 0);
_findclose(handle);
}
int main()
{
char path = ".";
printf("计算中...\n");
findAllCodes(path);
findALLDirs(path);
printf("你目前总共写了 %1d 行代码! \n\n", total);
system("pause");
return 0;
}
标答是101行,但我的运行之后是204行。请问有什么问题

你敲的没错。int countLines(const char *fliename){。。。这里*fliename应该是*filename,估计是上传时手误。
你敲的代码运行结果是101行。
你确定这个源文件当前目录下或子目录下没有其它.c源文件吗,如果有其它.c也是计算在内的。
