关于C语言第一个课后作业计数代码的一点问题
问题1:不论是自己手敲的代码还是答案复制的代码,运行下来都是已敲代码为0

#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)
{
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");
findAllCodes(path);
findALLDirs(path);
printf("目前你总共写了%ld行代码!\n\n",total);
system("pause");
return 0;
}
问题2:
是不是我放的位置不对?以后写的代码是都要放在当前目录下还是新建一个文件夹存放?

以后写的代码是都要放在当前目录下还是新建一个文件夹存放? 这是 C语言,不是 C++,把文件后缀改成 .c
后续代码想要用这个计数应该怎么做呀?
该放在哪个目录? 自己摸索后,发现所有代码的后缀改成.c就能被计数上了。nice呀!
