If the input is null or empty then, “ IsNullOrEmpty( Input ) “ The condition in the while is used to check if the input is null or empty.

The process starts with prompting user to enter S to start the stopwatch and Q to quit as shown in the code block below.
(ii) Timer = instance of the StopWatch class. (i) Input = used to store the user input. If the input is start -> throw an InvalidOperation exception Iv) If the input is stop -> stop the stopwatch and print the time span If the input is stop -> throw an InvalidOperation exception Ii) If the input is start -> start the stopwatch The main class will be given the responsibilities of taking the customer input and printing out the time span.īefore starting the coding, below is the losely written algorithm for this task. The features such as starting the stopwatch, stopping the stopwatch and noting the time span should be placed in one class say Stopwatch. So, let’s think about a way of organizing the code based on the responsibilities.
For those of you who are unware of this course I have given the question below.įor those, who can’t wait for the code I have given link to files here.īased on the exercise, we are supposed to write a program which allows users to start and stop the stopwatch and print the time span to the console. This time I am here with a C# tutorial.In this tutorial I am going to present you with the solution of first exercise problem in C# intermediate level course by Mosh (Moshfegh) Hamedani in Udemy.
