Loosely Typed

Definition: A loosely typed programming languages is typically one that does not require the type of a variable to be explicitly stated. Perl is a loosely typed language. You can put any type of data into a variable and perl will interpret it based on context:

$myVariable = 25;
$myVariable = "A String.";

C is not a loosely typed language (see strongly typed). You must declare the variable type before using it:

int myVariable;
myVariable = 25;
