Perl Language: How To Use Do While Loop in Perl Program

Learn How To Use Do While Loop in Perl Program. Perl offers 4 types of the loop, for, foreach, while and dowhile loop. So you get to use the loop depending on the context you want to use the loop. And the below video you can find how to use the dowhile loop in perl program.

Here's the syntax for the dowhile loop that you can check out.

do {
   statement(s);
}while( condition );

Here the statement means that you are adding the code which you want to repeat as long as the loop repeats. And another thing is that condition in the while loop makes it possible for that loop to repeat itself until the condition is met.

Perl code requires you to have the code stored in the .perl file extension file. This way when you run the perl code say it's in the file named helloworld . pl

You can run the perl file on command prompt like this.

That's it. You can now execute the perl code on your computer.
