Question

how to flowchart take an integer from the user and display the factorial of the number

Answer 1

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.
