Int * p [3] and int (* p) [3], int difference

Int * p [3] and int (* p) [3], int difference

The two are actually the differences between the numeric pointer and the pointer array. One by one:
Int * p [3]; // defines a three-dimensional array. Each element p [0], p [1], and p [2] are pointers to the int variable.
Int (* p) [3]; // defines a pointer pointing to a three-dimensional array.

The differences and relationships between the two can be described using a two-dimensional array:

Int * p [3]; // defines p [3] as a pointer array.
Int (* q) [3]; // defines q As an array pointer.
Int a [4] [3]; // defines a two-dimensional array

P [0] = & a [0] [0]; // you can assign a value to the element in p [3] for the address of any element in a [4] [3 ].
Q = a [1]; // a [1] is actually a three-dimensional array. Its elements include a [1] [0], a [1] [1], a [1] [2], so
// A [1] indicates the first address of the array. This address can be used to assign a value to q.
