Challen… x 100% (1:0) Codio Flode Collapse Challenges 3. 1. Challenge (array sum) Create a flode chart that inputs an arrays called numbers that will contain a series of random numbers. Add up all the array elements and output the result. To start assign your numbers arrays to 1, 2, 3, 4, 5. This program therefore, should output 15. Don’t forget to use the length property in order to determine when you loop will stop iterating. Check It!
The Correct Answer and Explanation is:
Here’s the correct answer for the 3.1 Challenge (array sum) in Codio Flowcharts (Flode):
✅ Correct Flode Structure Description:
- Start block
- Declare array
numbers = [1, 2, 3, 4, 5] - Declare variable
sum = 0 - Declare variable
i = 0 - Loop (While i < numbers.length)
- Add
numbers[i]tosum - Increment
iby 1
- Add
- End loop
- Output sum
- End
The program should correctly output:
CopyEdit15
🧠 Explanation
This flowchart challenge requires you to calculate the sum of all elements in an array using a loop. In this case, the array is initialized as numbers = [1, 2, 3, 4, 5]. This is a typical array of five integers. The goal is to iterate through the array, add each element to a running total (stored in a variable called sum), and then output the final result.
To do this, we first initialize the sum variable with 0. This acts as the accumulator where all elements will be added. We also create a counter variable i = 0 to control our loop and index the array.
The loop condition is based on the array’s length, accessed by numbers.length. This is important because arrays can change in size, and using length makes your loop dynamic. The loop continues as long as i < numbers.length.
Inside the loop:
- We access the current element using
numbers[i]and add it tosum. - We then increment
iby 1 to move to the next element.
After the loop completes, all array elements have been added to sum. In this specific case:
- 1 + 2 + 3 + 4 + 5 = 15
Finally, the program outputs the value of sum, which is the expected result.
This type of task reinforces key programming concepts: arrays, loops, indexing, accumulation, and using the .length property. It’s a great foundation for working with lists and handling data collections efficiently.
