第一课的小程序为啥我的只有7行?
我用的是WIN10系统编译器是DEV抄完也只有7行?这是为什么这和答案的101行差距也太大了。

我用VS2015运行,没有问题,101行。请问你用什么编译器编译?用DEV_C++不正常,186行
程序有问题,只能一行一行帮你查,需要一点时间 怕你等久了,你先试试下面的代码:
// 有些编译器对缩进有严格的要求,所以,请不要改变每一行前的空格!
// 如果程序文件是 *.cpp,则将第 50 行的 "/*.c" 直接改为 "/*.cpp"
#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)// 如果程序文件是 *.cpp,将此行的 "/*.c" 直接改为 "/*.cpp"
{
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("目前您总共写了 %1d 行代码! \n\n", total);
system("pause");
return 0;
} 试了一下,win10 系统下安装的 DEV_C++,运行这个程序,(无论程序的后缀是 .c 还是 .cpp)默认的都是 C++ 程序,只要将第 50 行的 "/*.c" 直接改为 "/*.cpp",运行就正确,输出103行。若不修改第50行,后缀为 .c 的程序,输出186行,后缀为 .cpp 的程序,输出为103行 风过无痕1989 发表于 2021-1-9 13:48

可我的输出是7行就离谱

怕你等久了,你先试试下面的代码:
现在 合适了谢谢大佬
