array of pointer & pointer to array

int (*p)[10];  // This type is a "pointer to array" with 10 elements.

int *p[10];    // This type is an "array of pointer" with 10 elements.

Practice: write down how many bytes the following statements need

int **P;                        // 4 bytes
int *p[];                        // 4 * sizeof array bytes
int (*p)[10];                 // 4 bytes
int *p[10];                    // 40 bytes
int (*p)[20][30];           // 4 bytes
