can not open the file
运行下面的代码,照着小甲鱼的代码敲的啊,然后显示 can not open the file#include <io.h>
#include <direct.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX 256
long total;
int countLines(const char *filemane);
void findAllCodes(const char *path);
void findALLDirs(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");

你这个文件路径不正确啊,那个path变量是需要你自己设置的,根据你要打开文件的路径来给它赋值,不然它这个路径根本不正确肯定无法打开文件,这个path里的路径必须是个有效路径。 这一句
sprintf(target , "%s%s", path , fa . name) ;
改为
sprintf(target , "%s/%s", path , fa . name) ;
试试看呢 本帖最后由 isdkz 于 2022-4-17 21:07 编辑
第一:handle = 写成了 handle ==
第二:%s/%s 少了 /
对你的代码修改如下,错的地方已在代码中写了注释
