How describe const pointer to an array in C/C++?

Question

I know the type which is pointer to an int[10] (ptr->int[10]) is int (*var)[10], but how to describe those of type blow?

the type which is pointer to the const int[10] (ptr->const int[10])

the type which is const pointer to the int[10] (const ptr->int[10])

the type which is const pointer to the const int[10] (const ptr->const int[10])

Answer 1

int (*ptr1)[10] = malloc(sizeof(int)*10);             // Pointer to int[10]
const int (*ptr2)[10] = malloc(sizeof(int)*10);       // Pointer to const int[10]
int (* const ptr3)[10] = malloc(sizeof(int)*10);      // const Pointer to int[10]
const int (* const ptr4)[10] = malloc(sizeof(int)*10);// const Pointer to const int[10]

*ptr1[0] = 10; // OK.
*ptr2[0] = 10; // Not OK.
*ptr3[0] = 10; // OK.
*ptr4[0] = 10; // Not OK.

ptr1 = realloc(ptr1, sizeof(int)*10); // OK.
ptr2 = realloc(ptr2, sizeof(int)*10); // OK.
ptr3 = realloc(ptr3, sizeof(int)*10); // Not OK.
ptr4 = realloc(ptr4, sizeof(int)*10); // Not OK.
