Question

Which statement demonstrates the value of an iteration in programming?
1. An iteration can be used instead of many repetitive lines of code in a computer program.
2. An iteration makes a program end without having to press keys on the keyboard.
3. An iteration formats the code in a program into a neat indented form.
4. An iteration controls the order in which a program executes code.

Answer 1

I don't know if you have any problems or questions then you have send me okay thanks so much

Answer 2

The correct answer to this question is option 1. An iteration can be used instead of many repetitive lines of code in a computer program.

Explanation:

• Iteration permits us to simplify the algorithm by declaring that certain steps will be repeated until told otherwise.

• This makes creating algorithms faster and simpler because they do not have to include a number of unnecessary steps.

• Once an algorithm has been designed and finalized, it must be translated into a code that a computer can study.

• Programs are created to implement algorithms. Algorithms comprise of steps. Programs comprise of statements. A statement is a single command or a single step.

• Iteration is applied in programming by utilizing FOR and WHILE statements.

• Iteration is frequently mentioned as ‘looping’, because when a program iterates it loops to a prior step.
