CEwhile
CEwhile is a term encountered primarily in programming education and informal discussions to denote a controlled or contract-based variant of the standard while loop. It is not part of any official language specification, and there is no single universal definition. In different sources, the acronym CE has been expanded in various ways, such as conditional execution or controlled exit, but the common thread is an emphasis on verifiable loop behavior rather than a distinct syntax.
Semantics and purpose: A CEwhile loop is typically described as structurally similar to a regular while loop,
Syntax and notation: Because CEwhile is not standardized, exact syntax varies by author. A typical presentation
Usage and significance: CEwhile appears mainly in textbooks and discussions of algorithm design and program verification.
