Strong typed language

A programming language that requires a variable to be defined as well as the variable it is. For example, C is a strong typed language, when declaring the variable you must also specify the variable type. In the below example the test variable is declared as an integer in the first line, the second line as a floating point, and the third line or character.

int test = 25;
float test = 2.3;
char test = 'e';

The opposite of a strong typed languages is a loosely typed language, such as Perl.
