Answer 1

If you want a multidimensional array, you just need to add a dimension such as:
char multidim[2][4]; // 2*4 array
For static arrays, you either need to specify the size or the content (so that the compiler can deduce the size)
Your variable "i" is not defined, such as your type Arrayp

Answer 2

Reading more carefully your code, I do not think you need a multidimensional array, but just a mono dimensional array, and in this case, only the size is missing
