iterací

Iterací refers to the process of repeating a set of instructions or operations multiple times. This is a fundamental concept in computer programming and mathematics, often employed to solve complex problems or to perform repetitive tasks efficiently. The core idea behind iteration is to break down a large problem into smaller, manageable steps that can be executed repeatedly until a desired outcome is achieved.

In programming, iteration is commonly achieved through loops, such as "for" loops and "while" loops. A "for" loop typically executes a block of code a predetermined number of times, while a "while" loop continues to execute as long as a specified condition remains true. Each execution of the loop's body is referred to as an iteration.

Iterací is crucial for tasks like processing large datasets, searching for specific information, or generating sequences of numbers. For example, to calculate the sum of all numbers from 1 to 100, a programmer would use iteration, adding each number to a running total in successive steps. This repetitive execution allows for the systematic handling of data and the automation of complex processes.

The concept of iteration also extends to fields outside of computer science. In mathematics, iterative methods are used to approximate solutions to equations that are difficult or impossible to solve analytically. In scientific research, iteration is often employed in simulations and experiments where a process needs to be repeated under varying conditions to observe its behavior. The efficiency and systematic nature of iteration make it an indispensable tool across various disciplines.
