Purpose: This program calculates the first 11 factorials  ( 0!, 1!, 2!, ... 10!)
         and stores them in an array  factor[10]


                */

#include <iostream.h>
#include <iomanip.h>


void main()
{
// declare the variables of the main function

int factor[11];   //  This is an array of eleven entries named as:
                    //   factor[0], factor[1], factor[2], .......,factor[10].

int m = 0;

factor[0] = 1;

cout << " \n\n     The factorials are: \n\n" ;
cout << setw(5)<< m <<" !"<< setw(15)<<factor[m]<<endl;

  /*    The output is :

  

     The factorials are:

    0 !              1

    2 !              2

    9 !         362880
   10 !        3628800


    DONE !
