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

I'm not sure if i get the question right but I will try to point this out.

There are pointers pointing to a type
e.g.:

int num;
int* p_num = # // this is pointing at the int

Moreover there are arrays (which in fact are pointers)

int num;    // an Integer
int* p_num; // a pointer. (can point at int's)
int arr[3]; // an Array holding 3 int's
arr[0] = 1; // + holding the values 1, 2, 3
arr[1] = 2;
arr[2] = 3;

p_num = arr; // because an array is just a pointer "p_num" num is now pointing at
             // + the first element in the array.
             // + ** THIS IS NOW A POINTER TO AN ARRAY **
num = *p_num;// num = 1

And there are arrays, which can hold multiple pointers:

int num1;
int num2;
int num3;

int* p_array[3];    // an array holding 3 pointer to int's
p_array[0] = &num1; // this is pointing at num1
p_array[1] = &num2; // num2, ...
p_array[2] = &num3;
                    // ** THAT IS AN ARRAY OF POINTERS **
