Question

Im quite confused that what is difference between these two initializations:

    int (*p)[10];

and

    int *p[10]

I know they both can point to 2D array whose element count in row is 10….

Answer 1

To elaborate a bit on the correct answers here already:

The first line:

 int (*p)[10];

declares that “p” is a pointer to the memory address of an array with the capacity of 10 ints. It can be read in English as: “integer-pointer ‘p’ points to 10 sequential ints in memory”.

The second line:

int *p[10]

Declares that “p[]” is an array of 10 pointers to integers. This is an array of memory addresses that point to integers. In this case, “p” is a sequence of 10 pointers in memory (which happen to be the memory addresses of other ints).
