Pointer to an array and Array of pointers

Question

As I am just a learner, I am confused about the above question. How is a pointer to an array different from array of pointers? Please explain it to me, as I will have to exp

Answer 1

POINTER TO AN ARRAY

Pointer to an array will point to the starting address of the array.

int *p; // p is a pointer to int
int ArrayOfIntegers[5]; // ArrayOfIntegers is an array of 5 integers, 
                        // that means it can store 5 integers.

p = ArrayOfIntegers; // p points to the first element of ArrayOfIntegers

ARRAY OF POINTERS

Array of pointers will contain multiple pointers pointing to different variables.

int* ArrayOfPointers[2]; // An array of pointers which can store 2 pointers to int
int A = 1;
int B = 2;
int *PointerToA ;
PointerToA  = &A ; // PointerToA is a pointer to A
int *PointerToB ; 
PointerToB  = &B ; // // PointerToA is a pointer to A
ArrayOfPointers[0] = PointerToA ; // ArrayOfPointers first element points to A
ArrayOfPointers[1] = PointerToB ; // ArrayOfPointers second element points to B
