If else statement in Perl

By Chaitanya Singh | Filed Under: Perl

In the last tutorial, we learnt about if statements in perl. In this tutorial we will learn about if-else conditional statement. This is how an if-else statement looks:

if(condition) {
   Statement(s);
}
else {
   Statement(s);
}

The statements inside “if” would execute if the condition is true, and the statements inside “else” would execute if the condition is false.

Example:

#!/usr/local/bin/perl

printf "Enter any number:";
$num = <STDIN>;
if( $num >100 ) {
   # This print statement would execute,
   # if the above condition is true
   printf "number is greater than 100\n";
}
else {
   #This print statement would execute,
   #if the given condition is false
   printf "number is less than 100\n";
}

Output:

Enter any number:120
number is greater than 100
