S1E2的课后作业
我用Dev c++照着把代码敲完了,
- #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;
- }
复制代码 运行结果却是0,检查了好几遍没有错误,然后把代码直接复制进去了试一下结果也是0,自己也不懂怎么找出问题,求助各位大佬了
第二个错误也是一样的
- sprintf(thePath, "%s/%s", path, fa.name);
复制代码
你在那两个函数找一找就能发现了
