Write a program named FahrenheitToCelsius that accepts a temperature in Fahrenheit from a user and converts it to Celsius by subtracting 32 from the Fahrenheit value and multiplying the result by 5/9. Display both values. Activity – 2: Create an enumeration named Month that holds values for the months of the year, starting with JANUARY equal to 1. Write a program named MonthNames that prompts the user for a month integer. Convert the user’s entry to a Month value and display it. Activity – 3: 1. Write a C# program named ProjectedRaises that includes a named constant representing next year’s anticipated 4 percent raise for each employee in a company. Also declare variables to represent the current salaries for three employees. Assign values to the variables, and display, with explanatory text, next year’s salary for each employee. 2. Convert the ProjectedRaises class to an interactive application named ProjectedRaisesInteractive. Instead of assigning values to the salaries, accept them from the user as input. Activity – 4: Each of the following files in the folder Debugging Exercises provided on Moodle has syntax and/or logical errors. In each case, determine the problem and fix the program. After you correct the errors, save each file using the same filename preceded with Fixed. For example, DebugTwo1.cs will become FixedDebugTwo1.cs. a. DebugTwo1.cs b. DebugTwo2.cs c. DebugTwo3.cs d. DebugTwo4.cs
