What is the primary purpose of iteration in a for loop?

• To stop a program from running
• To create random numbers
• To execute a set of statements for each item in a collection
• To define global variables

In the code 'for s in students', what does 's' represent?

• The entire students array
• A function name
• A global variable
• The loop variable

How is a loop variable different from a global variable?

• Loop variables can only be used inside the loop
• Global variables are always integers
• Loop variables have limited scope within the loop
• Global variables cannot be modified

In the context of the ice cream cone analogy, what does iteration represent?

• Counting the number of cones
• Buying ice cream
• Eating an entire ice cream cone
• Taking a small bite from each cone one after another

When using a loop variable before a dot, what unique approach is being demonstrated?

• Instructing the array element to carry out an action
• Deleting array elements
• Creating a new array
• Modifying the array directly

What is a key characteristic of a loop variable in a 'for' loop?

• It represents each element in the collection during iteration
• It cannot be modified
• It can only be used once
• It must be a global variable

In the example 'for s in students: s.step(1)', what action is being performed?

• Moving each student one step forward
• Counting students
• Creating a new student
• Deleting students

What are the two primary components of a for loop?

• Start and end points
• Function and method
• Loop header and loop body
• Variable and constant

In the context of a for loop, what does the 'loop variable' represent?

• A reference to individual elements in an array
• The array's memory location
• The total number of iterations
• The loop's execution speed

Why would a programmer choose a for loop over a simple times loop?

• For loops are always faster
• For loops only work with numbers
• For loops can work with specific collections of objects
• Times loops are more complex
