draw a flowchart that will add even numbers from 0 to 20 and display the sum​

A flowchart to add even numbers from 0 to 20 and display the sum can be represented as follows:Codegraph TD A[Start] --> B{Initialize Sum = 0, Number = 0}; B --> C{Number <= 20?}; C -- Yes --> D{Is Number Even?}; D -- Yes --> E{Sum = Sum + Number}; E --> F{Number = Number + 2}; F --> C; D -- No --> F; C -- No --> G[Display Sum]; G --> H[End];Explanation of the Flowchart:Start:The flowchart begins with the "Start" symbol, indicating the program's entry point.Initialize Sum = 0, Number = 0:This step initializes two variables: Sum to store the cumulative sum of even numbers, and Number as a counter starting from 0.Number <= 20?:This is a decision point. The program checks if the current Number is less than or equal to 20.Yes:If the condition is true, the flow proceeds to check if the Number is even.No:If the condition is false (i.e., Number is greater than 20), the loop terminates, and the program proceeds to display the sum.Is Number Even?:This is another decision point. The program checks if the Number is divisible by 2 with no remainder.Yes:If the Number is even, it is added to the Sum.No:If the Number is odd, it is skipped, and the flow proceeds directly to incrementing the Number.Sum = Sum + Number:If the Number is even, its value is added to the Sum variable.Number = Number + 2:The Number is incremented by 2 to get the next potential even number. This ensures that only even numbers are considered in the loop.Loop Back:The flow returns to the "Number <= 20?" decision point to continue the iteration.Display Sum:Once the loop condition becomes false, the final calculated Sum is displayed.End:The flowchart concludes with the "End" symbol, indicating the program's termination.
