2- The purpose of the method resize() in the IntegerArray class below is to dynamically change the size of the IntegerArray instance. This methid is implemented as follows: 1. create a new array with the desired size 2. copy the data form the old to new one 3. delete the old data 4. Make the old data pointer points to the newly created data 5. update the size field your task is to write the resize() method based on the above five steps.

![1- Write a class that allows you to define complex numbers in C++ and call it
complex. The class contains two private members named real and img. It also has a
constructor to initialize its members to values other than zero. Then, write a four
methods that implement the basic mathematical operations (+,-.*) for two complex
numbers.
