Write a program which reads in a single integer 0 <= n < 30 and prints out the factorial of n. Factorials get very big very quickly and can easily exceed the limits of a signed int that uses 4 bytes. If the value of factorial of n is too large to be stored in an int (>2,147,483,647), your program should print Can't handle this.

Python code along with step by step comments is provided below.

Python Code with Explanation:

# get input from the user

num = int(input("Enter a number: "))

factorial = 1

# check if the number is within the allowed range  

if num>=0 and num<=30:

# if number is within the range then run a for loop

   for i in range(1,num + 1):

# this is how a factorial is calculated

       factorial = factorial*i

# now check if the result is withing the limit or not

       if factorial>2147483647:

# if result is not within the limit then terminate the program

           print("Sorry, cant handle the result")

           exit()

# if result is within the limit then print the result

   print("The factorial of",num,"is",factorial)  

else:

# if input is not withing the range then print wrong input

   print("Sorry, Wrong input")

Output Results:

Enter a number: 10

The factorial of 10 is 3628800

Enter a number: 15

Sorry, cant handle the result

Enter a number: 35

Sorry, Wrong input
