@FishC_GPT 下面这段代码有什么错误
#include
#i ...
这段代码有一些错误:
1. 缺少头文件:`#include <stdio.h>` 和 `#include <string.h>`。
2. 函数名和变量名大小写不一致:`countlines()` 应该修改为 `countLines()`,`findALLCodes()` 应该修改为 `findAllCodes()`,`findALLDirs()` 应该修改为 `findALLFiles()`。
3. 在 `main()` 函数中调用的函数名大小写也需要修改。
4. `total` 变量没有初始化,默认会被赋予一个垃圾值。在使用之前应该将其初始化为0。
5. `system("paus")` 这段代码在Linux上无法执行。
以下是修改后的代码:
#include <stdio.h>
#include <string.h>
#include <io.h>
#define MAX 256
long total = 0;
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, "无法打开文件: %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 findALLFiles(const char *path)
{
struct _finddata_t fa;
long handle;
char thepath;
strcpy(thepath, path);
if((handle = _findfirst(strcat(thepath, "/*"), &fa)) == -1L)
{
fprintf(stderr, "路径 %s 错误!\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);
findALLFiles(thepath);
}
} while (_findnext(handle, &fa) == 0);
_findclose(handle);
}
int main()
{
char path = ".";
printf("计算中...\n");
findAllCodes(path);
findALLFiles(path);
printf("目前你总共写了 %ld 行代码!\n\n",total);
getchar();
return 0;
}
希望这次能编译运行成功!
