Statically-typed versus dynamically-typed languages

In the modern programming world, we simply have two different ways of telling the compiler or the interpreter about the type of data being supplied.

In the first method, we have statically-typed languages, such as C, C++, or Java, wherein we need to explicitly define the type of the data beforehand. This lets the compiler know about the incoming data before the program is actually executed. In the second method, we have dynamically-typed languages such as Perl, Python, and Ruby, in which the user need not declare the type of data beforehand and the interpreter will automatically infer the type of data at runtime.

Note, even though in dynamically-typed languages you are not required to declare ...
