#include <stdio.h>
void main(){
  int i,f=1,num;//delare i and num and assign 1 to f as integer

  printf("Input the number : "); //we show to user to imput a number
  scanf("%d",&num);   // we scan for integer int type and assign it to num

  for(i=1;i<=num;i++)       // here we run for loop till i is less or equal to num
      f=f*i;    //here we put factorial formula

  printf("The Factorial of %d is: %d\n",num,f); //we show the result to user
