What’s the outcome of calling a method?

Sometimes a message is printed to the console:

Console.WriteLine("Hello World!");

Sometimes a value is returned:

Math.Floor(15.6); // Returns 15

Sometimes a variable is altered:

int number;
bool success = Int32.TryParse("10602", out number); 
// number is 10602 and success is True

If you don’t understand all of the code examples, that’s okay! By the end of this lesson you will be able to:

• Define methods with output using the return and out keywords
• Recognize and resolve errors related to method output
