Types of programming language

Tell the computer how to achieve a goal, by giving a sequence of instructions.

Examples: Fortran, Pascal, Basic, Cobol.

Tell the computer what goal to achieve, by giving a specification.

Examples: Prolog, OBJ3, Lisp.

Prolog and Lisp are not entirely declarative - they have imperative features too, e.g. for input and output.
