What is the most important difference between a while statement and a \(d o-w h i l e\) statement?

Short Answer

Expert verified
Answer: The most important difference between a 'while' statement and a 'do-while' statement is that in a 'while' statement, the loop condition is checked before the commands within the loop are executed, whereas in a 'do-while' statement, the commands within the loop are executed prior to checking the loop condition. As a result, the 'do-while' loop will always execute its loop body at least once, while a 'while' loop might not execute the loop body at all if the condition is initially false.

Step by step solution

01

Description of while Statement

In a 'while' statement, the loop condition is checked before the execution of the commands within the loop. If the condition is false from the beginning, the loop body will never be executed.
02

Description of do-while Statement

In a 'do-while' statement, commands within the loop are executed first, and then the loop condition is checked. This means the loop body will be executed at least once, even if the condition is false from the beginning.
