Of course, you usually want something to happen, and it's best not to assume that it's impossible for all matches to fail.

It can be used inside of any type of conditional more on that later , and in this case, a failure to include a break at the end of each case will result in code after the case being executed, even if subsequent case matches fail. So far, we've looked at code for making a decision once. What if you want to repeat an action, over and over, as long as a condition holds? That's where while and do When your code reaches a while statement, the program evaluates the conditional "Is it windy?

Once code execution is complete, the conditional will be evaluated once more. If the conditional is still "TRUE", the code will execute again. This repeats over and over, until the conditional evaluates to "FALSE" or a break statement is encountered.

You can nest an if statement or a switch , or another while , or in fact anything you want inside your while loop:.

So, with that loop, I'll fly my kite until the wind gives out or my boss gets mad at me. In this case, the code inside the brackets runs once, even if the conditional is false. In other words, regardless of the state of the wind, I'll go out and drag a kite around, but if the wind isn't there, I'll give up. Finally, by sticking "TRUE" into the conditional, it's possible to create code that will execute forever:.

With that chunk of code, I'll just keep dragging my kite around the field forever, regardless of wind, my boss's satisfaction with it, hunger, cougars, etc. It's still possible to break out of that code using the break statement, of course; it will just never cease execution on its own.

The last type of conditional execution we need to consider is the for loop. The syntax of a for loop looks like this:. Within the for loop parentheses are three semicolon separated statements.

The first one is the iterator: the variable which we are changing with each pass. It's also where the iterator's initial value is set. The center one is the comparison we'll do after each pass. Once that comparison fails, we break out of the loop. The last statement is what we want to do after each pass through the loop. In this case, we want to increment the iterator by one. The most common error in a for loop is an off-by-one error: you mean for the code to execute 10 times, but it ends up executing 9 times, or 11 times.

Contributors: SFUptownMaker. Introduction Digital, or boolean, logic is the fundamental concept underpinning all modern computer systems. In this tutorial you will learn about Digital circuitry Digital logic circuits can be broken down into two subcategories- combinational and sequential. Programming Digital logic is important in programming, as well. Suggested Reading Before getting started, it might be a good idea to review our tutorial on binary numbers , if you haven't already.

What is Electricity? Binary Analog vs Digital Logic Levels. Combinational Logic. Sequential Logic Combinational logic is great, but without adding sequential circuitry, modern computing would not be possible. Sequential Circuit Elements As is the case with combinational logic, there are several basic circuit elements which form the building blocks of sequential circuits.

D-type Flip-Flop. Boolean Logic in Programming All of this can be applied in the programming world, as well. Bitwise Logic When we talk about "bitwise" logic, what we really mean is logical operations which return a value. Translated into C, that sentence might look like this: if raining! We could just as easily have had a numeric value in one of the subclauses: if raining! Flow Control Now that we can create complex logical statements, let's look at the things we can do with the answers to those questions.

A variation on while loops is the do Resources and Going Further Understanding digital logic is a crucial skill in electronics.
