draw a flowchart to sum all the even numbers between 1 and 20 inclusive and then display the sum
To draw a flowchart that sums all the even numbers between 1 and 20 inclusive, you can follow these steps:
1. Start: Begin the flowchart with a start symbol.
2. Initialize Variables: Create a process symbol to initialize a variable "sum" to zero.
3. Loop: Use a loop to iterate through the numbers from 1 to 20.
4. Check Even: Inside the loop, use a decision symbol to check if the current number is even.
5. If Even: If the number is even, flow through the "Yes" path and add the current number to the variable "sum".
6. If Not Even: If the number is not even, flow through the "No" path and continue the loop without adding anything to "sum".
7. Next Number: After checking each number, increment the loop variable by 1 and flow back to the "Check Even" decision symbol.
8. End Loop: When the loop reaches 20, flow out of the loop.
9. Display Result: Use a process symbol to display the value of the variable "sum".
10. End: End the flowchart with an end symbol.
Here is the flowchart representation:
