Write a C# console application that has ONE method to perform the four basic arithmetic operations of add, subtract, multiply, and divide. In the main program, first print a line on the console showing your Name. Call the method you created above with each of the four arithmetic operations. You have to pass the method two integer numbers as well as a flag for which operation you want the method to perform. The method performs the operation on the numbers you pass from the main program and prints out the result on to the console.Your method must print nice messages so the user understands what the result is all about. Also, fix the following problems: a) The whole application terminates with error if the main program asks the method to divide by zero. b) When the main program passes some unknown flag for the operation.
