Answer 2

Answer:

Programming Language not mentioned...Done in JAVA and python

Java approach:-

//Program to print the factorial of given number

package Programmer;

import java.util.*;

public class Fact{

public static void main (String ar []){

Scanner sc=new Scanner (System.in);

System.out.println("Enter a number");

int n=sc.nextInt(); int f=1;

for(int I=1;I<=n;I++){

f * =I;

}

System.out.println("Factorial of "+n+" is"+f);

}

}

_____

Python approach:-

n,f=(int)(input("Enter a number")),1

for I in range(1,n+1):

f=f *I

print("Factorial of ",n," is",f)
