While C#: How to Use this Programming Statement

while c sharpC# programming is one of the best languages to learn for up and coming programmers. This level of object oriented programming lacks some of the more complicated fundamentals that are found in other languages, and it serves as a good base to learn those languages as well. If you want to really try your hand at programming, try the Udemy course C# introduction.

In C# programming there are several statements used to help make programming easier. These statements are pre-programmed into the language, and they allow you to do some amazing things. One of the statements commonly used in programming is the while statement. This statement allows the user to do just exactly what the name suggests, and that is making the program perform a task while something is true.

What Does the While Statement Do?

As a programmer you will witness the while statement in two key loops. A loop is a programmer’s way of doing a task repeatedly. Combining a loop with a while statement involves you having that task be done repeatedly while that condition is being met.

There are two types of loops that involve the while statement. These loops are the do while loop and the basic while loop. Both loops have their uses, and although they have some specific aspects about them there are situations when the loops can actually be interchangeable.

  • While Loop

With a while loop you set a condition first and then you tell the program to perform a certain task. This is a simple loop, and you will find it in many programs written by both beginners and experts in the field.

  • Do While Loop

On the other hand, a do while loop is a bit less common. This loop sets the condition after the task. This means that the program will perform the task first and then check the condition for it decides to perform the task again.

Using the While Statement

An example of the while statement in action is a program when a program is constantly checking the status of something. Consider a situation where your bank constantly notifies you that your bank account has reached below a certain balance, for example below $40.00. Now the bank has a system set up where it notifies you of your balance when it reaches below this point, tells you what the balance is, and emails the data directly to you.

A while statement can be used to program the bank to do this. With a while statement, you would set a condition, which in this case is while your bank account balance is below $40.00, and then have the program execute a command while this condition is true.

For the bank example, the program will execute the command of emailing you and informing you that your account balance has reached below its threshold and what your current account balance may be.

In programming, using a while statement like this is a pretty simple task, and you can learn how to do it easily. If you want to get skilled at programming even though you’re a beginner, the Udemy course Programming for Complete Beginners in C# is a great resource.

Examples of the While Statement in Programming

One of the best ways to understanding programming is to look at a program yourself, break it down, and then try creating your own. Consider the example mentioned above and look at the use of a basic while statement in a while loop.

int balance = 39;
while (balance < 40)
{
Console.WriteLine("Your current balance is {0}",balance);
Balance++;
}

In the example above we have a basic while loop that sets a condition and runs. What the program does is a list of things. First of all, the program sets the balance of the account to 39. The program then puts the balance into the while loop.

The condition of the while loop is set between the parentheses. The while loop states that while the balance is less than 40 the following statement will be written out, which means that since our balance is 39 the while loop will run.

In this instance the while loop prints out or says what is in the quotation marks. The loop tells the user their current balance.

For this basic type of code there’s a balance++ in the program. This adds 1 to the value of the program, which increases the value of the balance to 40. Now that the value is 40, the program won’t run the loop anymore.

Using the Do While Loop

The above example used a while loop, but below you will see the same type of program using the do while loop instead. Here is an example of what the same program would do if it were put in a do while loop.

int balance = 39
do
{
Console.WriteLine("Your current balance is {0}",balance);
Balance++;
}
while (balance < 40)

In this situation we set the balance just like before, but the loop is a bit different. In this loop we tell the program to notify the user of their current balance, and then add 1 to it before the loop even starts.

After the loop does the task once it checks the condition of the while loop and sees whether or not it will do it again, but the balance has been increased from 39 to 40, which means that the while loop will now read it as 40 and not continue on with the loop itself.

The key difference between the do while loop and the while loop is that the do loop executes at least once before actually performing the loop. There’s always the guarantee of a do loop executing, but the same cannot be said for a while loop. Since the while loop constantly checks the condition before executing any commands, the while loop can never run at all in the program and you simply wouldn’t notice.

Of course the above example is only a simple taste of what you could program. Imagine changing this program where it actually calculated your account balance after you made a withdrawal or deposit. You could make it so that the program only runs the while loop once a day until you raise your balance to the appropriate levels. There are tons of things you can do with the loop and c# programming in general once you get the basics down.

It’s easy to find some c# programming project ideas to help give you a bit of experience if you’re having some trouble. For many people, the best way to program is to create something on their own and see how it works or understand why it didn’t work.

Mastering C# Programming

It takes years of experience before someone is able to really master programming, and even then they can make mistakes. Don’t be frustrated if you have some trouble understanding a few methods or statements in the language. Learning how to program is really like learning a completely different language, and that requires understanding the rules of that language perfectly before you become fluent in it. There are some guides out there though to help you master c# programming and create whatever you want with it.

The Udemy course Explore the Fundaments of C# Programming will teach you all of the important aspects of programming. You should also check out Udemy for more information if you are looking to get started in the programming business – the site has everything you need for success.
