c++

Write a program to allow user enter an array of structures, with each structure containing the firstname, lastname and the written test score of a driver.

Your program should use a DYNAMIC array to make sure user has enough storage to enter the data.

Once all the data being entered, you need to design a function to sort the data in descending order based on the test score.

Another function should be designed to display the highest, lowest and average test scores in all the test takers along with their name.
