What are the key principles to consider when designing an atomic programming structure?

When designing an atomic programming structure, it is important to consider key principles such as modularity, encapsulation, and reusability. Modularity involves breaking down the program into smaller, manageable components. Encapsulation involves hiding the internal workings of a component and only exposing necessary information. Reusability involves designing components that can be easily reused in different parts of the program. These principles help create a more organized and efficient atomic programming structure.
