How do you represent an iterative process in code?
You can develop code to represent iterative processes by using a `for` loop, which is designed for such tasks.

How do you represent an iterative process in code?
You can develop code to represent iterative processes by using a `for` loop, which is designed for such tasks.
What is the relationship between `for` loops and `while` loops?
A `for` loop can be rewritten as an equivalent `while` loop, and a `while` loop can also be rewritten as an equivalent `for` loop.
How do you determine the final result of a process controlled by a `for` loop?
To determine the result, you must trace the loop's execution, tracking variable changes through each iteration until the Boolean expression becomes false.
Iterative Statement
An iterative statement is a control flow structure that allows a block of code to be executed repeatedly. A `for` loop is one type of iterative statement.
Describe the complete execution flow of a `for` loop.
First, the initialization runs once. Then, the Boolean expression is checked; if true, the loop body executes, the update runs, and the cycle repeats from the Boolean check.
What is a `for` loop?
A `for` loop is a type of iterative statement used to represent and execute repetitive processes in code.
How many times is the initialization statement in a `for` loop executed?
The initialization statement is executed only once, before the first evaluation of the Boolean expression.
In a `for` loop's iteration, when is the update statement executed?
The update statement is executed after the entire loop body runs and before the Boolean expression is evaluated for the next iteration.
What are the three parts of a `for` loop header?
The three parts of a `for` loop header are the initialization, the Boolean expression, and the update.
What is the role of the Boolean expression in a `for` loop?
The Boolean expression is evaluated before each potential iteration; the loop continues to execute as long as this expression is true.
