Constants and variables

Code:

#include <iostream>

#include <conio.h>

using namespace std;

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

{

  cout << " This is the number of two : 2" << endl;//String

  cout << " This is the number of two : "<< 2 << endl;//constants

  getch();

  return 0;

}

Integer type variables:

             It is range of two byte.

Code:

#include <iostream>

#include <conio.h>

using namespace std;

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

{

  int i; //Declaring

  i=2; //Initializing

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

  getch();

  return 0;

}

Unsigned Integer type variables:

Code:

#include <iostream>

#include <conio.h>

using namespace std;

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

{

   unsigned int i; //Declaring

  i=2;// //Initializing

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