Why array is declared as int *arr

#1

Why do we declare the array as int *arr, instead of int arr. Why do we put * ?

#2

hello @sonalbera

we can declare array by two ways.
one is static allocation like ->
int a[n];

one is dynamic allocation like->
int *a = new int[n];
here new operator will allocate memory of n block and return its base address which we are storing in pointer a.

both will work in same manner,u can use any of them.

for classes and objects use dynamic allocation because n is not known to us before hand.
