傳遞âgetGradesFromFileâ的參數1將指針整數，未作鑄

Question

我寫一個程序來讀取記錄一個文件，提取一些網絡的視場爲VLA的，使用插入排序排序，使用二進制搜索搜索用戶SPECI網絡版目標並打印出結果。

芽我不斷收到這些錯誤：

Answer 1

void getGradesFromFile(int size, 
         char line[], 
         int studentI_D[], 
         int test1, 
         int test2, 
         int test3, 
         char grades[]); 

size是int類型，但你逝去的"grades.csv"這是因此它的地址將被paased一個字符串，並因此變得指針。

line[]是數組因此一個指針，就類型的傳遞sizeint

studentI_D[]是int類型的陣列。您正在通過類型char的str依次類推......

您的函數聲明和定義獲得了7個參數，但傳遞了8個參數，因此導致錯誤。

你需要檢查歇歇吧。這些都是愚蠢的錯誤。
