FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Writability describes the ease with which a language can be used to create programs for a given domain. ∎ Be careful not to compare things which. should not be. Most of the features that affect readability affects also writability.

Detailed explanation-2: -Orthogonality helps writability, unless features are too orthogonal, in which case errors may go undetected. A language is expressive if it provides features that make it easier to perform common tasks. APL provides powerful array operators. C++ provides increment and decrement operators.

Detailed explanation-3: -The language evaluation criteria are: • Readability: the ease with which programs can be read and understood. Writability: the ease with which a language can be used to create programs. Reliability: conformance to specifications (i.e., performs to its specifications).
