HOW TO drow flowchart
TO add the number 1 to 100 and display the sum
1. Start: Begin the flowchart with the "Start" symbol.
2. Initialize variables: Create a rectangle with "Initialize variables" written inside. Create a variable "sum" and set it to zero.
3. Loop: Draw a diamond shape with "Loop" written inside. The condition for the loop is that the variable "i" should be less than or equal to 100.
4. Add 1: Draw a rectangle with "Add 1" written inside. Add 1 to the variable "i".
5. Add current number to sum: Draw a rectangle with "Add current number to sum" written inside. Add the current value of "i" to the variable "sum".
6. End loop: Draw a line from Step 3 to Step 4 with "Yes" written above it. Add "No" above the line that connects back to the loop diamond symbol.
7. Display sum: Draw a rectangle with "Display sum" written inside. Display the value of the variable "sum".
8. End: Draw the "End" symbol at the bottom of the flowchart.
The completed flowchart should look like this:

To draw a flowchart to add the numbers 1 to 100 and display the sum, you can follow these steps:
Step 1: Start the flowchart
- Start the flowchart by drawing a rounded rectangle or an oval shape. Inside this shape, write "START" or "BEGIN" to indicate the beginning of the program.
Step 2: Declare variables
- Draw a rectangle shape and write "Declare Variables" inside it. This step is used to declare variables that will be used in the program. In this case, you will need a variable to hold the sum.
Step 3: Initialize variables
- Draw a rectangle shape and write "Initialize Variables" inside it. This step is used to set the initial values of variables. In this case, you need to set the sum variable to 0.
Step 4: Loop through numbers 1 to 100
- Draw a diamond shape and write "For i = 1 to 100" inside it. This step is used to create a loop that will iterate from 1 to 100.
- Connect the diamond shape with an arrow pointing downwards to the next step.
Step 5: Add current number to sum
- Draw a rectangle shape and write "Sum = Sum + i" inside it. This step is used to add the current number (i) to the sum.
- Connect this rectangle shape with an arrow pointing downwards to the next step.
Step 6: Repeat the loop
- Draw a circle shape and write "Increment i" inside it. This step is used to increment the value of i by 1 for the next iteration of the loop.
- Connect this circle shape with an arrow pointing towards the diamond shape drawn in Step 4.
Step 7: Check if loop is complete
- Draw a diamond shape and write "Is i > 100?" inside it. This step is used to check if i is greater than 100, indicating that the loop is complete.
- Connect this diamond shape with two arrows pointing downwards; one arrow should connect with the next step if i > 100, and the other arrow should connect back to the rectangle shape drawn in Step 5 if i is not greater than 100.
Step 8: Display the sum
- Draw a rectangle shape and write "Display Sum" inside it. This step is used to display the final sum value.
- Connect this rectangle shape with an arrow pointing downwards to the next step.
Step 9: End the flowchart
- Draw a rounded rectangle or an oval shape. Inside this shape, write "END" or "STOP" to indicate the end of the program.
- Connect this shape with an arrow pointing towards the rectangle shape drawn in Step 8.
Step 10: Connect the flowchart steps
- Connect the shapes using arrows to indicate the flow of the steps in the program.
That's it! Following these steps will help you create a flowchart to add the numbers 1 to 100 and display the sum.
