One is called FailingGradesException which messages "You have failed the course." The other one is called InvalidGradeException which messages "Grade is not valid!". In the main program, ask for an integer user input grade. If grade is greater than 100, call InvalidGradeException and if grade is below 75, call FailingGradesException. Print "You passed!" if no exceptions occur. Inputs 1. Grade Sample Output Enter grade: 85 You passed!arrow_forwardWhen the user is done the program should calculate the MPG by calling GetMPG, catching the exception if the user did not enter any values. Then it should show the result. Stream Errors coutarrow_forward
