对照一下小甲鱼的代码,发现有两个错误。
分别在第51行和第79行。
你把"%s/%s"中间的斜杠符号漏了,导致查找的目录不正确。
修改后代码如下:
- #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)
- {

- long handle;
- char thePath[MAX],target[MAX];
-

- if((handle=_findfirst(strcat(thePath,"/*.c"),&fa)) != -1L)
- {
- do
- {
- sprintf(target,"%s/%s",path,fa.name); // sprintf(target,"%s%s",path,fa.name)
- total+=countLines(target);
- }while(_findnext(handle,&fa)==0);
- }
-
- _findclose(handle);
- }
-
