使指針整數沒有轉換

Question

我有我的代碼有點問題。編譯器告訴我，我的代碼在沒有強制轉換的情況下生成一個指向整數的指針。現在我對這意味着什麼都不熟悉，所以也許有人可以指出（打算非常有意）我是朝着正確的方向發展。另外任何一般的提示將非常感謝！

確切的錯誤是：

Homework3.c: In function ‘main’: 
Homework3.c:32: warning: passing argument 1 of ‘add’ makes pointer from integer without a cast 
Homework3.c:16: note: expected ‘int (*)[5]’ but argument is of type ‘int’

Answer 1

sales[SALESPERSON][PRODUCTS]在sales在SALESPERSON位置引用的數組的PRODUCTS位置返回整數。你只需要通過sales：

add(sales, data, totals); //same thing with totals 

您還沒有給出數組的函數的長度，所以你的定義應該僅僅是：

void add(int[][] sales, float data, float[] totals)
