Computer Programming Languages -- Expressions and Assignment Statements

Imperative programming languages make use of expressions and assignment statements to convey sequential steps of a calculation. The notation used is very much like that for algebraic equations, but, unlike an algrebraic equations which make logical assertions relating the components of the equation, programming language expressions and assignment statements describe actions to be performed, so that the same symbols may have different meaning at different places in the same statement, and the same statement may have different meanings depending on what has happened previously to the state of the machine.
