小白提问,S1e2的课后作业编译运行没问题,显示的统计结果有问题
#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;
}
这是我自己抄的代码。然后我也尝试过复制了小甲鱼给的代码,编译运行之后也是同样的提示,行数为0
求各位大佬,帮忙看看,谢谢~@小甲鱼
.cpp 改 .c 本帖最后由 lxmmmmmm 于 2020-4-13 14:42 编辑
再问一个小白问题,为啥把.cpp改成.c就可以运行了呢? lxmmmmmm 发表于 2020-4-10 17:45

因为这个程序是统计C语言源代码的行数,不是统计C++
好哒,谢谢大佬~ 哪里的,cpp改为.c啊 程序写完之后,系统会让你保存,保存的界面上,编辑文件名的上一排你就可以选择是.cpp or .c
