int(*arr2)[8]; arr2 is a pointer (the parenthesis block the right-left) to an array of 8 integers. int*(arr3[8]); arr3 is an array of 8 pointers to integers. This should help you out with complex declarations. Here is a great article about reading complex declarations in C:unix...

https://stackoverflow.com/questions/8767166/passing-a-2d-array-to-a-c-function The major reason for problems when passing regular arrays, 1D or 2D or more, the array devolves into pointers, the function has no clue what the array dimensions are. ...

Then, employ known, logical, repeatable, precise transformations to obtain a functioning grammar. I had performed some work on this over here: https://github.com/kaby76/scrape-c-plus-plus-spec. We can try to use some of the transformations in the existing cpp grammar, but there's really ...
2.Pass Array to Function C語言 將陣列傳到function時,由於陣列可能很大,若用pass by value的方式傳進function,勢必造成大量copy的動作而降低效能,C語言是靠pointer的方式,將陣列第一個元素的位址以pointer的方式傳進function。 1 /* 3 4 Filename : ArrayPassToFunctionCStyle.c ...
Because of the array-to-pointer implicit conversion, pointer to the first element of an array can be initialized with an expression of array type: int a[2]; int* p1 = a; // pointer to the first element a[0] (an int) of the array a int b[6][3][8]; int (*p2)[3][8] =...
