How are curly brackets used?

These keys are most commonly used in curly bracket programming languages such as C, Java, Perl, and PHP to enclose groups of statements or for a block of code. Below is an example of how an enclosed statement looks like in Perl.

$value = 0;
do {
if ($value >= 10) {
print "Value is equal to or greater than 10. Ending.";
} until ($value >= 100);

In the above example, are two enclosed statements using curly brackets. The first group is the do loop that continues to increase the value of $value variable up to 100. Within that group is the if statement that checks to see if $value is greater than or equal to 10 and if it is print a message and exit the script.
