碼云：[https://gitee.com/ikaros-521/using-C-to-get-user-s-fans]
Linux的話，去掉頭文件conio.h，getch()，稍加改動就行了
用到的工具：[Wget](http://www.gnu.org/software/wget/)

## 效果展示

相關(guān)打印可以修改 mix.c 自行優(yōu)化

## 編譯
gcc mix.c -o mix

## 運行

直接運行mix.exe 或 打開cmd，cd到工作目錄，輸入 mix.exe 運行(如果生成文件后，程序沒有自動刪掉，請手動刪除）

### 用戶信息填寫

**user_info.conf**

```bash
speed:1
bilibili:uid
cnblogs:id
csdn:id
gitee:id
github:id
zhihu:id
```

speed速度就是循環(huán)的速度。
其他分別對應(yīng)各平臺的id，如果沒有也隨便填一個，不需要可以在 mix.c 中注釋掉對應(yīng)平臺。
