Question:You have been given the responsibility of creating a class named CalcSalary that will
determine the salaries of Certkiller .com's staff. The CalcSalary class includes methods to increment and
decrement staff salaries. You would like to invoke the IncrementSalary and DecrementSalary methods
dynamically at runtime from the sales manager application when needed. You decide to use the Salary
delegate to invoke these methods.
