下面給出的代碼是來自CS50的問題集3的答案。 請看看功能：init， draw， move， won 並提出了一些改進，我可以做到的。 其實我得到一些我不明白的錯誤。CS50 pset3 - 十五的遊戲
/**
* fifteen.c
*
* Implements Game of Fifteen (generalized to d x d).
*
* Usage: fifteen d
*
* whereby the board's dimensions are to be d x d,
* where d must be in [DIM_MIN,DIM_MAX]
*
* Note that usleep is obsolete, but it offers more granularity than
* sleep and is simpler to use than nanosleep; `man usleep` for more.

我得到這個錯誤，我無法解決。
格式指定類型「INT」，但該參數的類型爲「依賴型」
關於你的開頭段落，Stack Overflow不是[代碼評論]（http://codereview.stackexchange.com）SO的唯一主題是這個錯誤的含義。您應該編輯帖子及其標題以反映這一點。 –
請發佈[最小示例]（http://stackoverflow.com/help/mcve），並給出完整的錯誤。另外，不是每個人都會知道「CS50」是什麼，但是真相被告知它與問題並不相關，所以我建議刪除對它的引用。 – jerry
