} [02:22] You will extend the assignment one. Here is the description.

(a)(i) Create a City structure that will have the following members: name (string type), population (int type), area (float type) and numOfCOVIDPatients (int type).

(ii) In the main function, create an array of size N of City structure type. This array will be used by all the functions. You will have a lower case n to keep track of the number of cities in the array. You will pass this array and # of cities as arguments to the functions.

(b) Create a function takeCitiesInfoFromKeyboard that takes a City structure array and n as parameters. It takes information of all the Cities from keyboard and stores in the City structure array. Do you know that arrays are passed by reference?

(c) Create a function computeAverageNumOfCOVIDPatients that takes a City structure array and n as parameters. It computes and returns the average number of COVID patients of all the Cities.

(d) Create a function findAboveAvgCOVIDPatientCities that takes a City structure array and n as parameters. It finds all the Cities that have higher than average number of COVID patients and displays their information in a tabular format with following values (including the given column heading):

City Name City Population City Area Num of City COVID Patients
