Ohjausrakenne

Ohjausrakenne refers to a control structure in programming. It dictates the order in which statements are executed. Different control structures allow for varying degrees of flexibility and complexity in program flow. The most basic is sequential execution, where statements are run one after another in the order they appear. Conditional statements, such as if-else, allow programs to make decisions based on certain criteria. If a condition is true, one block of code is executed; otherwise, another block might be executed, or no action taken at all.

Loops are another fundamental type of control structure. They enable repetitive execution of a block of code. Common loop structures include for loops, which typically execute a specific number of times, and while loops, which continue as long as a given condition remains true. More advanced control structures can include switch statements for handling multiple conditions, and constructs for managing function calls and returns. The choice of control structure significantly impacts a program's logic and efficiency. Understanding and effectively utilizing ohjausrakenne is crucial for writing functional and well-structured software.
