Programmistruktuuride, often translated as program structures or programming constructs, refers to the fundamental building blocks and organizational principles used in computer programming. These structures dictate how instructions are sequenced, how decisions are made, and how data is managed within a program. Understanding program structures is crucial for writing efficient, readable, and maintainable code.

Common program structures include sequential execution, where instructions are processed one after another in the order they appear. Another key structure is selection, which allows programs to make decisions based on certain conditions. This is typically implemented using constructs like if-else statements or switch cases. Iteration, also known as looping, provides a way to repeat a block of code multiple times. Common iteration structures include for loops, while loops, and do-while loops.

Beyond these basic control flow structures, program structures also encompass data structures, which organize and store data in an efficient manner. Examples include arrays, linked lists, stacks, queues, trees, and graphs. The choice of data structure significantly impacts a program's performance. Furthermore, program structures involve modularity and abstraction, where complex programs are broken down into smaller, manageable units or functions, promoting reusability and simplifying development. Object-oriented programming introduces further structural concepts like classes and objects. Effective use of program structures leads to well-organized and logical code.
