新人求问学C第一课的课后作业问题!!
本帖最后由 JeremyPan7 于 2020-11-10 23:05 编辑求问!学C第一课的课后作业为啥执行不出来,已经按着代码一行行打了,检查过了 ,还是发现不了问题在哪,代码如下
#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 += 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("目前你总共写了 %ld 行代码!\n\n",total);
system("pause");
return 0;
}
编译报错如下

第42行的位置加个空格
