The university is creating a new application that can either assign student awards and bursaries or provide academic warnings based on several criteria. The university administrators have come to you to program a solution that meet their requirements, outlined below: 1. The application must state whether a student is on the "Dean's List" if their GPA is 10.0 or better. 2. The application must state whether a student continues to receive their entrance scholarship if their GPA is 10.0 or better. 3. The application must state whether a student will be given an academic warning if their GPA is less than a given threshold. As the threshold differs according to program, the application must be able to accept any threshold when making this determination. 4. The application should accept an administrator's input for each of the determinations above and should allow the administrator to enter data for as many students as they wish without having to restart the application. Once the…
