In this exercise, you will create a class with several methods and use delegates to call these methods. Your program should be able to: $-$ complete the following exercise: $1.$ Use a Func delegate that points to multiple methods, each performing a different operation $($addition$,$ subtraction, multiplication$)$ on three parameters $($double$,$ int, double$).2.$ Iterate over the invocation list of the Func delegate to call each method individually. $3.$ Use an Action delegate that points to multiple methods that print results to the console, also performing operations $($addition$,$ subtraction, multiplication$)$ on three parameters $($double$,$ int, double$).4.$ Finally, display the output of both the Func and Action delegates. Requirements: $$ Implement a class DelegateDemo with the following methods: o funA: Adds the parameters and returns the result. o funB: Subtracts the second and third parameters from the first and returns the result. o funC: Multiplies all three parameters and returns the result. o funD: Adds the parameters and prints the result. o funE: Subtracts the second and third parameters from the first and prints the result. o funF: Multiplies all three parameters and prints the result. $$ In the Main method: o Create a Func delegate that points to funA, funB, and funC. Iterate through its invocation list and call each method. o Create an Action delegate that points to funD, funE, and funF. Call the delegate to print the results. Expected Output: The program should print the results of each operation performed by both the Func and Action delegates.
