how to flowchart take an integer from the user and display the factorial of the number
Here is a basic flowchart for taking an integer from the user and displaying the factorial of that number:
[Start] --> [Initialize: Factorial = 1] --> [Input: integer from user]
--> [Loop: i = 1 to integer] --> [Multiply: Factorial = Factorial * i]
--> [End Loop] --> [Output: Factorial] --> [End]
Some notes on the flowchart:
- This flowchart assumes that the input integer is greater than or equal to 0 (since the factorial of a negative number is undefined) and that the output will be an integer (since fractional factorials are not supported).
- The "Initialize" step sets the value of the Factorial variable to 1, since any factorial calculation will start with that value.
- The loop runs from 1 to the input integer (inclusive), multiplying the Factorial variable by each integer in the range.
- The "End Loop" step indicates that the loop has finished running.
- The "Output" step displays the final value of the Factorial variable.
- The "End" step indicates the end of the program.
To create a flowchart for taking an integer input from the user and displaying the factorial of the number, follow these steps:
1. Start the flowchart.
2. Display a message asking the user to enter an integer number.
3. Create a box labeled "Input" to represent the input process.
4. Connect the "Input" box to the message box with an arrow.
5. Create a variable to store the input value.
6. Create another box labeled "Assign" to represent the assignment of the input value to the variable.
7. Connect the "Input" box to the "Assign" box with an arrow.
8. Create a box labeled "Factorial" to represent the calculation process.
9. Inside the "Factorial" box, initialize another variable to store the factorial result and set it to 1.
10. Create a loop box labeled "Loop"
11. Inside the "Loop" box, calculate the factorial by multiplying the result variable with the input number. Subtract 1 from the input number in each iteration until it becomes zero.
12. Connect the "Factorial" box to the "Loop" box with an arrow.
13. Inside the "Loop" box, create a decision box labeled "Condition" to check if the input number is equal to zero.
14. If the input number is not equal to zero, loop back to the "Factorial" box and continue calculating the factorial.
15. If the input number is equal to zero, exit the loop and move to the next step.
16. Create a box labeled "Output" to represent the display of the factorial result.
17. Connect the "Loop" box to the "Output" box with an arrow.
18. Inside the "Output" box, display a message showing the factorial value obtained.
19. Connect the "Output" box to the end of the flowchart.
Keep in mind that a flowchart is a visual representation, so you can use different shapes or symbols based on your preference or the standards followed in your organization.
