Calculate the Factorial of positive number in the range of 0 to 10.

#include "stdafx.h"

#include <iostream>

using namespace std;

int main()

{

int num,i,fact=1;

cout<<"Enter the number "<<endl;

cin>>num; 

if ((num==1)||(num<=10)) 

{

for(i=num;i>1;i--) 

{

fact*=i; //factorial formula 

}

cout<< "factorial of " <<num<<"="<<fact<<endl; 

}

else

cout<<"your enter number= " << num << "is invalid"<<endl;

system("pause");

return 0;

Introduction Programming Fundamental | what is Computer |

=>What is Computer system: 

                                          

                                       Computer System

                                       1)Software

                                       2) Hardware

  1) Software has Also two types name as; 

                                                         a) System Software.

                                                         b) Application softwares.

a)System Software: 

                               System Software is a type of Software in which Control all the Hardware in the system is called System software.

    Example of System Software is :

                                       1) Operating language

                                       2) Compilar

                                       3) Translator

                                       4) Debuggars

                                       5) Drivers

b) Application Softwares:

                                           We can defined that Application Software is also a subclass of system Software which fullfill need the requirements of user .Specially Application Software are Design for user which perform their task directly through computer.some of the example of Application software is below.

•  MS OFFICE
•  GAMES

 EMAIL filter is also a type of Application software.

                  *Application Software has also two types:

                                          a) Ready made Softwares.

                                          b) Geomatrically Softwares

a)Ready made software: 

                                        Ready made are  those software which  are  developed by the request of user for general purposes not necessary that all the module of such software are for the every user.

b) Gemmatically:
