Iteration:

Iteration is a programming concept that involves repeating a sequence of instructions until a specific condition is met. This is often achieved using loops in programming languages.

Repeating a Sequence:

In the context of programming, when we talk about repeating a sequence, we refer to executing a set of instructions multiple times. This is useful when we need to perform a certain task multiple times without having to write the same code over and over again.

Condition-Based Repetition:

The key idea behind iteration is that the repetition is based on a condition. The sequence of instructions will be repeated until the specified condition evaluates to true. This allows for flexibility in controlling how many times the sequence should be repeated.

Looping Structures:

In programming, loops are used to implement iteration. There are different types of loops such as for loops, while loops, and do-while loops, each serving a specific purpose in repeating a sequence of instructions until a condition is met.

Importance in Programming:

Iteration is a fundamental concept in programming as it allows for efficient execution of repetitive tasks. By using iteration, programmers can write compact and readable code that performs tasks efficiently without unnecessary duplication of code.

Therefore, the statement "The iteration structure involves repeating a sequence until a condition is met" is correct as iteration is the concept used in programming to achieve this repetitive behavior based on a condition.
