Question: In C$++$ Complete the Course class by implementing the FindStudentHighestGpa$()$ member function, which returns the Student object with the highest GPA in the course. Assume that no two students have the same highest GPA. Given classes: Class Course represents a course, which contains a vector of Student objects as a course roster. $($Type your code in

In C$++$ Complete the Course class by implementing the FindStudentHighestGpa$()$ member function, which returns the Student object with the highest GPA in the course. Assume that no two students have the same highest GPA. Given classes: Class Course represents a course, which contains a vector of Student objects as a course roster. $($Type your code in here.$)$ Class Student represents a classroom student, which has three private data members: first name, last name, and GPA. $($Hint: GetGPA$()$ returns a student's GPA.$)$ Note: For testing purposes, different student values will be used. Ex$.$ For the following students: Henry Nguyen $3\mathrm{.}5$ Brenda Stern $2\mathrm{.}0$ Lynda Robison $3\mathrm{.}2$ Sonya King $3\mathrm{.}9$ the output is: Top student: Sonya King $($GPA: $3\mathrm{.}9)$

Define a function named GetWordFrequency that takes a vector of strings and a search word as parameters. Function GetWordFrequency$()$ then returns the number of occurrences of the search word in the vector parameter $($case insensitive$).$

Then, write a main program that reads a list of words into a vector, calls function GetWordFrequency$()$ repeatedly, and outputs the words in the vector with their frequencies. The input begins with an integer indicating the number of words that follow.

Ex: If the input is:

$5$ hey Hi Mark hi mark
