iterációkat

Iterációk refers to the process of repeating a set of instructions or operations multiple times. In computer programming, this is fundamental to solving problems that involve processing collections of data or performing repetitive tasks. The most common constructs for implementing iterations are loops, such as `for` loops and `while` loops.

A `for` loop is typically used when the number of iterations is known beforehand or can be easily determined. It often involves initializing a counter, setting a condition for continuation, and defining how the counter changes after each iteration. A `while` loop, on the other hand, continues to execute its block of code as long as a specified condition remains true. This is useful when the termination point of the iteration is not known in advance.

Beyond programming, the concept of iteration is prevalent in many fields. In mathematics, iterative methods are used to approximate solutions to complex equations, where a process is repeated until a desired level of accuracy is reached. In design and development, iteration is a core principle of agile methodologies, where products are refined through successive cycles of development, testing, and feedback. This iterative approach allows for flexibility and continuous improvement. The key aspect of any iteration is the ability to reuse a process or set of steps, making it a powerful tool for problem-solving and creation.
