The relationship between a pointer and a two-dimensional array

Pointers refer to multidimensional arrays

int a[3[4] = {{1,3,5,7},{9,One, },{, (+),+, +}};

Two- dimensional arrays
A[0]	==	1	2	5	7
A[1]	==	9	11	13	15
A[2]	==	17	19	21st	23

OK, two-dimensional arrays in our eyes, the equivalent of three one-dimensional arrays; A represents the first address of a two-dimensional array. In a two-dimensional array, we need to pay special attention to the address that a+1 points to is actually a[1].

We set the "int" type in the example, and each INT in 32-bit vs represents 4 bytes. Suppose: The first address of "a" is 2000, then the address of "a+1" is 2000+4*4 = 2016;
