Loops (6b Question)

In programming, loops are used to run a block of code repeatedly, either until a predetermined condition is fulfilled or for a predetermined number of times. Loops are crucial for completing repetitive operations, managing the flow of our program, and iterating over arrays, lists, and other data structures. Loops are a fundamental programming element to automate repetitive activities, cycle over data structures, and regulate the flow of our program based on specific conditions. A for loop consists of three components: 1. Initialization: The for loop’s opening statement is the only instance of this component of the code that gets run. It is used to set the initial value of the loop counter and to initialize the loop variable(s). Although not required, this section is typically used to declare and initialize counter variables. 2. The second component of the for loop is used to check a condition prior to each loop iteration. The loop keeps running if the condition is true. The loop ends if the condition is false. Each cycle starts with a check of this condition. 3. The third section of the for loop is used to update the loop variable(s) at the conclusion of each iteration. Usually, this is done to increase or decrease the loop counter. At the conclusion of each iteration, the update statement is carried out.
