Hoare Logic is a formal system used in computer science to reason about the correctness of computer programs. It uses a set of logical assertions, called Hoare triples, which are written in the form P C Q. Here, P is a precondition, C is a command or program, and Q is a postcondition. The logic helps to prove that if the precondition holds before executing the command, the postcondition will hold afterward. The main goal of Hoare Logic is to provide a framework for verifying that programs behave as intended. By using logical reasoning, developers can ensure that their code meets specific requirements and avoids errors. This approach is particularly useful in critical systems where reliability is essential.
