C++ - TUTORIAL WHILE AND DO WHILE

Hi.. welcome to my site in “We Are Knowledge”… In here you want getting many IT knowledge.. like as: PHP, HTML, MYSQL, COBO, PASCAL, and other IT knowledge.

Now Iwant giving you tutorial about “C++”and discuss of “using WHILE and DO WHILE”..

To be found between “WHILE” and “DO WHILE.

WHILE is command for doing looping until conditions are met, and although not yet received grades if condition are met, the program will be out of order.

DO WHILE is command for doing looping until condition are met, generating at least one value, mean although condition are met, keep getting value.

Ok.. direct to program…

You can copy this coding and paste in your compiler..

Example 1 :

#include <iostream.h>

#include <conio.h>

int main ()

{

  int a;

  cout << "Enter the starting number > ";

  cin >> a;

  while (a > 0)

  {

    cout << a << ", ";

    --a

    ;

  }

  cout << "FIRE!";

  getch();

}

And press “alt  + F9”  >> compile

And press “ctrl + F9” >> running

And result is :

If you input 5 !!

Enter the starting number > 5

5, 4, 3, 2, 1, FIRE

You can too copy this coding and paste in your compiler..

Example2:

#include <iostream.h>

#include <conio.h>

int main ()

{

  unsigned long b;

  do

  {

    cout << "Please enter number (0 to end): ";

    cin >> b;

    cout << "You entered: " << b << "\n";

  }

  while (b != 0);

    cout << "Ok.. Right";

  getch();

}

And press “alt  + F9”  >> compile

And press “ctrl + F9” >> running

And result is :

This is program require your input number or value “0”.. if you not input number or value “0”, the program will continue to run.

NOTE ::

If you using copy and paste, please change all quotes (" ") or (' ' ).

Ok.. just it..

I hope you understand with my article…
