Long type variables:

             It is range of four byte.

Code:

#include <iostream> 
#include <conio.h>
using namespace std;   
int main (int argc, char *argv[])
{
     long i; //Declaring
     i=2; //Initializing
     cout << " This is the number of two : "<< i << endl;
     getch();
     return 0;
     }

Code view in dev compiler:

Compile the program Ctrl+F9

      Run program Ctrl+F10

Unsigned long type variables:

Code:

#include <iostream>

#include <conio.h>

using namespace std;

int main (int argc, char *argv[])

{

   unsigned long i; //Declaring

  i=2;// //Initializing

  cout << " This is the number of two : "<< i << endl;

  getch();

  return 0;

}

Code view in dev compiler:

Compile the program Ctrl+F9

      Run program Ctrl+F10

Code Exp1:

#include <iostream>

#include <conio.h>

using namespace std;

int main (int argc, char *argv[])

{

long AmerAge=30, AmaraAge=29; //Declaring & Initializing

  cout << "This is the Amer Age: "<<AmerAge<<endl

        << "And the Amara Age: "<<AmaraAge<<"\n";

  getch();

  return 0;

}

      Run program Ctrl+F10

Code Exp2:

#include <iostream>

#include <conio.h>

using namespace std;

int main (int argc, char *argv[])

{

  long numbertable, multipliertable ; //Declaring & Initializing

  cout << "Please enter the number for which you want a table :  ";

  cin>>numbertable;

  cout<< "Please enter the multiplier to which you want a table : ";

  cin>>multipliertable;

  cout<<"\n"<<numbertable<<" X "<<multipliertable<<" = "

      <<numbertable*multipliertable;

  getch();

  return 0;

}
