Difference between Static and Dynamic Programming ?

A dynamic language (Lisp, Perl, Python, Ruby) is designed to optimize programmer efficiency, so you can implement functionality with less code. A static language (C, C++, etc) is designed to optimize hardware efficiency, so that the code you write executes as quickly as possible.

In Programming languages: Static almost always means fixed or bound at compile time, and cannot thereafter be changed. Dynamic almost always means not fixed or bound until run time, and therefore can change during the course of execution.
