Which of the following is a type of iteration statement?

A DO WHILE loop is indeed a type of iteration statement, which is used to repeatedly execute a block of code as long as a specified condition remains true. This type of loop first checks the condition after executing the code block at least once, which allows for flexibility in scenarios where the block of code should run at least one time before the condition is evaluated.

Iteration statements are critical in programming as they enable the execution of code multiple times without needing to write the same code repeatedly, thereby improving efficiency and readability. The ability to create loops such as DO WHILE or FOR loops allows programmers to manage repetitive tasks effectively. In a DO WHILE loop, the program continues to execute the contained statements until the condition evaluates to false, providing control over the flow of the program.

Other options provided, such as the IF statement and CASE statement, are primarily used for making decisions based on conditions, allowing the program to take different paths but not for repeating actions. The FOR loop, while another type of iteration statement, is not the chosen answer in this case, but it still supports iterative processes in a different format.
