loop invariant उदाहरण वाक्य
उदाहरण वाक्य
- The loop invariant plays an important role in the intuitive argument for soundness of the Floyd-Hoare rule for while loops.
- The loop invariant does not affect the meaning of the program and, in some sense, might be considered as unnecessary.
- For example, a loop invariant is a condition that is true at the beginning and end of every execution of a loop.
- The loop invariant has to be true before each iteration of the loop body, and also after each iteration of the loop body.
- However, the loop invariant is required to help the automated verifier using in the Whiley Compiler to prove this function meets its specification.
- "' Whiley "'is a general purpose statically typed and supports formal specification through function preconditions, postconditions and loop invariants.
- In fact, the loop invariant is often the same as the inductive hypothesis to be proved for a recursive program equivalent to a given loop.
- In general, loop invariant dependencies and lexically forward dependencies can be easily vectorized, and lexically backward dependencies can be transformed into lexically forward dependencies.
- The loop invariant must be shown to hold on entry to the loop, for any given iteration of the loop and when the loop exits.
- In this case, the declaration prevents the need for an additional loop invariant of the form where i > = 0 which would otherwise be necessary.
