Document Summary

An extremely powerful and flexible problem solving tool. Something that every engineer needs to understand and be able to use. Values: the information (or data) stored and manipulated by computer programs. Expressions: a syntactic entity that denotes a value. Atomic expression is an identifier or a literal. Compound expression is formed by applying an operator to other expressions. The value of an expression is obtained by evaluating the expression. Types: a syntactic entity that denotes a collection of values of similar form. Type errors occur when a value of one type is used, where a value of another type is expected. Variables: a variable is a linguistic entity whose meaning can vary, the name bounded to a value, or an expression that deno tes the value. Constants: a linguistic entity whose meaning is fixed, such as true and false. Statements: a syntactic entity that states something to be done. A program is merely a sequence of statements.
