c语言课后题提问
《带你学C带你飞》【第一季】第二节课课后作业 动动手照着模板抄了一边,改了不少地方,但还是没法运行(编译器提示的看不懂)。有没有大佬帮忙看看啊,跪谢!{:5_111:}
下面是我抄的代码,原文请见:https://fishc.com.cn/forum.php?mod=viewthread&tid=66283&extra=page%3D1%26filter%3Dtypeid%26typeid%3D570
我是windows系统
#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 *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;
}
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 += countLine(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);
findeALLDirs(thePath);
}
}while (_findnext(handle, &fa) == 0);
_findclose(handle);
}
int main()
{
char path = ".";
printf("计算中...\n");
findAllCode(path);
findALLDirs(path);
printf("目前你总共写了 %1d 行代码 !\n\n, total");
system("pause");
return 0;
} 四处书写错误,主要是大小写和字母拼写错误。修改如下,请注意注释:
#include <io.h>
#include <direct.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX 256

return 0;
}
while ((temp = fgetc(fp)) != EOF)
{

{
count++;
}
}
fclose(fp);
return count;
}

{
do
{

total += countLines(target);//countLine书写错误
}while (_findnext(handle, &fa) == 0);

return;
}
do
{

continue;
if( fa.attrib == _A_SUBDIR )
{
sprintf(thePath, "%s/%s", path, fa.name);
findAllCodes(thePath);
findAllDirs(thePath);//findeALLDirs书写错误
}
}while (_findnext(handle, &fa) == 0);
_findclose(handle);
}
int main()
{
char path = ".";
printf("计算中...\n");
findAllCodes(path);//findAllCode书写错误
findAllDirs(path);//findALLDirs书写错误
printf("目前你总共写了 %1d 行代码 !\n\n, total");
system("pause");
return 0;
} 感谢大佬!!!{:5_109:}
