Question
I'm stuck on this question and I don't know how I should be approaching this. What should I do?
![1. Implement and grow a dynamic array using pointer arithmetic.
a) Use the provided main function (see below).
b) Implement a populate function which stores values from 0 to size
into the array p using pointer arithmetic to access array locations.
c) Implement a print function which prints the values of the array
p using pointer arithmetic.
d) Implement a printMemory function which prints the memory addresses
of all elements in array p using pointer arithmetic.
e) Implement a grow function which resizes the existing array from
the initial size to
new size using pointer arithmetic.
f) Verify via the output that the new array is a distinct memory space
from the original array.
