Question

4- Write a program by using function that asks the user for entering a positive integer
number (a) and then calculate the factorial of the number. Draw the Trace Table
(8 Marks)( k/2, T/2, C/2, A/2)
Enter a number: 4
Factorial (4) = 4! =4*3*2*1=24

use python pls

Answer 1

BECAUSE OF THE IDENTATION PROBLEM WHILE SUBMITTING THE CODE SO THAT IM ALSO GIVING YOU THE SCREENSHOT SO THAT YOU CAN REFER IT :

main.py 1 def factorial(n): # factorial function 2 if n == 1 : # if n is 1 return n 4 else: 5 return n * (n - 1) # recursfive function Nm 01 7 n = int(input("Enter the number: ")) # read the number 8- if n == 0 : # if n is zero 9 print("Factorial of ois : 1") 10- else: 11 print("Factorial of", n, "is :", factorial(n)) # print the result

PYTHON CODE :

def factorial(n): # factorial function
if n == 1 : # if n is 1
return n
else:
return n * (n - 1) # recursive function

n = int(input("Enter the number: ")) # read the number
if n == 0 : # if n is zero
print("Factorial of 0 is : 1")
else:
print("Factorial of",n,"is :",factorial(n)) # print the result

INPUT & OUTPUT :

Enter the number: 4 Factorial of 4 is : 12 ... Program finished with exit code 0 Press ENTER to exit console.

* fact. (n-1) ។ food (3) /l 3 tact (2) / IN 2 fact (1) 4*3*2*1 24
