Summary

   

In this hour you learned how to use C#'s decision constructs to make decisions in C# code. You learned how to use if statements to execute code when an expression evaluates to true and to use else to run code when the expression evaluates to false. For more complicated decisions, you learned how to use else if to add further comparisons to the decision construct and nest if structures for more flexibility.

In addition to if, you learned how to use switch to create powerful decision constructs to evaluate a single expression for many possible values. You learned how you can check for multiple possible values using a fall through case statement. Finally, you learned how to use goto to jump to any predefined position in code.

Decision-making constructs are often the backbone of applications. Without the capability to run specific sets of code based on fluctuating situations, your code would be very linear and hence very limited. Get comfortable with the decision constructs and make a conscious effort to use the best construct for any given situation. The better you are at writing decision constructs, the faster you'll be able to product solid and understandable code.
