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[MAX],target[MAX];
-
- 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[MAX];
-
- 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[MAX]=".";
-
- printf("计算[size=6][/size]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
