Exam Scripting-and-Programming-Foundations Topic 1 Question 60 Discussion

Actual exam question for WGU's Scripting-and-Programming-Foundations exam
Question #: 60
Topic #: 1
Which output results from the given algorithm?

Suggested Answer: C Vote an answer

The algorithm depicted in the image is a simple loop that iterates 5 times. Each iteration multiplies the current value of i by 2 and adds it to the variable sum. The loop starts with i equal to 1 and sum equal to 0. Here's the breakdown:
* First iteration: i = 1, sum = 0 + (1 * 2) = 2
* Second iteration: i = 2, sum = 2 + (2 * 2) = 6
* Third iteration: i = 3, sum = 6 + (3 * 2) = 12
* Fourth iteration: i = 4, sum = 12 + (4 * 2) = 20
* Fifth iteration: i = 5, sum = 20 + (5 * 2) = 30
However, the algorithm includes a condition that checks if sum is greater than 10. If this condition is true, the algorithm outputs the value of i and stops. This condition is met during the third iteration, where sum becomes
12. Therefore, the algorithm outputs the value of i at that point, which is 3.
References: The explanation is based on the standard behavior of loops and conditional statements in programming. For more information on algorithms and their implementation, you can refer to resources like
"Introduction to Algorithms" by Cormen et al. and online platforms like GeeksforGeeks1.
