- GPA Calculator Students are concerned about their GPA. They need to calculate it accurately every semester to monitor their progress. Develop a GPA calculator that follows the AOU regulations (AOU-OU Grade Scale) using C# programming language. The application asks the student to enter his numeric grade of each course and the course's credit hours. Accordingly, the application calculates the student's GPA after converting the numeric grade to letter grade. The GPA calculation should produce floating-point results. Display the results rounded to the nearest hundredth. You should store the letter grades of all student's courses in an array. The final grade of the student should be also calculated. Sample I/O Enter the course grade (-1 to end): 93 Enter the course credit hours: 3 Enter the course grade (-1 to end): 74 Enter the course credit hours: 2 Enter the course grade (-1 to end): 60 Enter the course credit hours: 3 Enter the course grade (-1 to end): -1 The grades of your courses…Please answer in C# Write a program named TemperaturesComparison that allows a user to input five daily Fahrenheit temperatures that must range from −30 to 130.

If every temperature is lower than the previous one, display a message Getting cooler. If the temperatures are not entered in either ascending or descending order, display a message It’s a mixed bag. Finally, display the temperatures in the order they were entered, and then display the average of the temperatures. Your program's output should look like the following: Getting warmer: 70 74 77 78 81 Average: 76If you have a String named firstName, type the line of code that defines an integer named firstNameLength as the length of the String firstName.
