Write a C++ program that will input from the user a positive number n and find its factorial. Don’t forget to validate the input. The factorial of a positive integer n (denoted by n!) is defines as the product of the integers from 1 to n. n! = 1* 2 * 3 * ... * (n - 1...

The output of the above program is: Factorial of 4 is: 24 2. Find factorial using Recursion To find the factorial,fact()function is written in the program. This function will take number (num) as an argument and return the factorial of the number. ...
# Python program to find the factorial of a number using recursion def recur_factorial(n): """Function to return the factorial of a number using recursion""" if n == 1: return n else: return n*recur_factorial(n-1) # take input from the user num = int(input("Enter a number: "...
这个你是运行时候报的错吗？？运行的时候，你要输入：java Factorial 4 这样的命令，然后回车。第三个参数，就是你要求factorial的数。
In GNU Pascal this program works without any problems. program factorial; function fact(n: integer): longint; begin if (n = 0) then fact := 1 else fact := n * fact(n - 1); end; var n: integer; begin for n := 0 to 16 do writeln(n, '! = ', fact(n)); end....
