semantics of programming languages

Semantics of programming languages refers to the meaning behind the code—what each instruction or statement does when executed. It defines how the syntax (structure) of the code translates into actions or effects within a computer, ensuring that programs behave as intended. Understanding semantics helps developers predict and verify what a program will do, beyond just writing syntactically correct code. In essence, semantics bridges the gap between the written code and its real-world effects, providing a clear understanding of the program's behavior and functionality.
