program semantics

Program semantics refers to the meaning or behavior of a computer program—that is, what the program does when executed. It describes the outcomes and effects of executing each part of the code, ensuring that the program performs its intended functions correctly. Think of it as understanding the "story" the program tells through its operations, variables, and commands, rather than just the written code. Clear semantics help developers verify, reason about, and debug programs, ensuring that they behave as expected in all situations.
