Question

How does a WHILE loop start?

a) while (i <= 10; i++)
b) while (i <= 10)
c) while i = 1 to 10
d) while (i < 10; i++)

Answer 1

The correct way to start a while loop is option b) while (i <= 10), where 'while' initializes the loop and the condition i <= 10 determines when the loop will stop executing.

Step-by-step explanation:

A while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. The correct syntax for starting a while loop in languages like C, Java, and JavaScript is b) while (i <= 10). There is no semicolon after the condition in a while loop, and the action of incrementing a variable, like i++, is typically done inside the loop's body, not in the while statement itself.
