Perl If Else: Understanding Programming

microsoft access 2010 tutorialPerl is a highly developed programming language that has been used for various applications. The language has several features, which include setting conditions. When you’re programming, you have to set conditions for the program to understand when it should do something. For example, think about your bank account where you’ve had it established that it moves a small amount of money from one account to another every month. There may be a situation where you don’t have any money in your account. Instead of the bank taking money from your account despite there being nothing there, you can set a condition to prevent it from ever happening.

This is one of the common aspects of programming, and it’s something that practically every programmer learns how to do when they’re just starting out. If you want to really learn about the importance of conditional statements and the different ways to create them, then check out the Udemy course Beginning Perl.

Perl If Else

One of the basic types of conditional statements to create is the if else statement. The if else statement sets a condition that, when met, will continue to execute the program. If the condition is not met, then the program will ignore the rest of the program and continue onwards.

The basic skeleton of an if statement is if (conditional statement) {executed code if condition is met;}.

An if statement can be made without an else, but then the program simply stops if the condition is not met. In order to keep the program for checking for new conditions, the else statement can be used. The else statement is used to give the program something to execute if the original condition isn’t met. For example, say you were creating a program that identified if a person was a millionaire. The condition would be if the person is a millionaire then write down, “you’re a millionaire”, else, if the person is not a millionaire, then write down, “you’re not a millionaire.”

Conditional statements are used to create a lot of different programs. A common type of program that people are creating is applications, which can be found on smartphones and other portable devices.

Perl If Else Example

Knowing the concept behind the Perl if else conditional statement is one thing, but if you really want to get the hang of it, then you should really look at some examples. Below you will find a simple example of an if else statement.

$x = 15;
if ($x > 20)
{
print “$x is greater than 20!”;
}
else
{
print “$x is not greater than 20!”;
}
print “<br/>”;

The program first sets up a variable where $x is equal to 15. Then you see the if condition is set, which is that if $x is greater than 20 then the program will write out “$x is greater than 20!”, but since this is not the case the program moves on to the else statement.

Since the else statement is automatically executed because the if statement is not true, then the program prints out “$x is not greater than 20!”

As you can see, the way it is all written is pretty simple. There are only a few lines of code that goes into creating your conditional statements. If you want, you can try expanding on these conditional statements and creating your own programs.

One thing that you should try is working with Perl operators. There are various types of Perl operators out there, and if you’re a beginner programmer it would be a good idea to work with them as you try out different conditional statements.

Programming Professionally

This is just a small piece of Perl, but the language has a lot more to offer and different features that can be incorporated tino it. Perl is a high-level programming language, which means that there is demand for people to do it professionally. If you have enough skill and you can create your own Perl programs, then you may be able to program for a pretty high wage.
