Expressions and Control Structures
Sense and purpose of programs is the manipulation of some data represented by variables. In general, manipulation cannot simply be done by the assignment of certain values, but by the evaluation of expressions and the assignment of the evaluation’s result to variables. Thus, expressions specify how values have to be calculated, i.e. they describe rules for elaborating a value. The elements of expressions are operands (may be function calls) which are combined by operators.
