Which of the following expressions correctly represents the value of f after the first iteration of the loop in the Factorial function?
Understand the Problem
The question is asking which expression correctly represents the value of the variable 'f' after the first loop iteration in a function calculating a factorial. We will need to analyze the structure of the Factorial function and the loop it contains to determine the correct answer.
Answer
n
The value of f after the first iteration of the loop in a factorial function is typically n, where n is the starting value or the first number to be multiplied in calculating the factorial.
Answer for screen readers
The value of f after the first iteration of the loop in a factorial function is typically n, where n is the starting value or the first number to be multiplied in calculating the factorial.
More Information
In the context of calculating factorial using a loop, the value of the product (usually stored in a variable like 'f') is initialized and updated with each integer from 1 to n. The first update in the loop multiplies the initial value with 'n'.
Tips
A common mistake is misunderstanding the initialization and iteration process. Remember that a loop for factorial starts its calculations from the base case, typically from n down to 1.
