Iteration is a fundamental concept in programming where a sequence of instructions is repeated multiple times. It's commonly used to automate repetitive tasks or to repeatedly check for conditions within a program.
In programming, there are two main types of iteration: definite iteration and indefinite iteration.
Definite Iteration: This type of iteration repeats a block of code for a specific, known number of times. It's predictable and often used when the number of repetitions is predetermined.
Indefinite Iteration: This type of iteration repeats a block of code until a certain condition is met, without a set number of repetitions in advance. It stops when the condition becomes true or false, depending on the logic.
