Definition: A strongly typed programming languages is one that requires the type of a variable to be explicitly stated. C is a strongly typed language. You must declare the type of data a variable will store for C to interpret it:
int myVariable;
myVariable = 25;
Perl is a loosely typed language. There is no need to declare the variable type before using it:
$myVariable = 25;
$myVariable = “A String.”;
