有大佬帮忙看看哪里出bug了吗，我复制过去运行也是显示o行代码，小甲鱼的课后作业来着
#pragma warning(disable:4996)#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)

findAllCodes(thePath);
findALLDirs(thePath);
}
} while (_findnext(handle, &fa) == 0);
_findclose(handle);
}
int main()
{
char path = ".";
printf("计算中...\n");

printf("目前你总共写了 %ld 行代码！\n\n", total);
system("pause");
return 0;
}
把当前代码所在文件夹下的代码文件后缀全改成 .c 即可
这个程序是检测.c文件的代码行数
你看一下你的程序文件是.c还是.cpp？
