Determining If a Student Should Be on Probation Due to Their GPA (C++ Program)

Question

A student is put on probation if their GPA is below 2.0. Complete the Course class by implementing the CountProbation() member function, which returns the number of students with a GPA below 2.0.

Given classes:

1. Class Course represents a course, which contains a vector of Student objects as a course roster. (Type your code in here)
2. Class Student represents a classroom student, which has three data members: first name, last name, and GPA.

Hint: Refer to the Student class to explore the available functions that can be used for implementing the CountProbation() function.

Note: For testing purposes, different student values will be used.

Ex. For the following students:

Henry Cabot 3.2

Brenda Stern 1.1

Lynda Robison 2.4

Jane Flynn 1.8

the output is:

Probation count: 2
