here's something to play with:

let's increment an integer until it goes negative. then display the maximum posisitve integer for your version of c++.

void max_int_test() {
  int i = 0;
  int max = 0;
  printf ("please wait ");
  while( i >= 0 ) {
    max = i;
	if( max % 100000000 == 0 ) {
      printf (".");
	}
    i++;
  }
  printf ("the largest positive int on this PC is %d i = %d", max, i);
}

You may also like this (C++)

#include <iostream>
using namespace std;

int main()
{
int x = 0;
while ( x <= 200 )
{
cout<< x << endl;
++x;
}
cout<<"Done!" << endl;
cin.get();
return 0;
}
Enjoy :tazz:

Are you looking for strictly C++ stuff????
Private Sub 
'the following will take a string and reverse it

Command1_Click()

'get word from textbox
originalword = Text1.Text

'loop as many times as there are letters in the string
Do until counter = len(originalword)

    'track the counter
     counter = counter+1

    'get letter in position "counter" (equal to x turn of the loop)
    letter = Mid(originalword, Counter, 1)

    'place letter at front of a new string.
    word2 = letter + word2

'end loop
Loop

'show new string
Text2.Text = word2
End Sub


EDIT OK, i Just read your other threads, scratch this - forgive my intrusion :tazz:

Loops would be useful in a character counter.

#include <stdio.h>
#include <string.h>

int main()
{
    printf("Character Counter \n\n\n");
    int x = 0;
    while (x == 0)
    {
    char string[10000];
    printf ("\nInput string: ");
    gets (string);
    printf ("String is %u characters long\n",strlen(string));
    }
}

Loops is also useful in image processing where u can do stuff such as turning a colored picture to grayscale, doing gaussian effect on the pic and etc....sort like what u can do for Photoshop.

It is because you need to use loop to extract information if each pixel of the picture and manipulate it to your desired effect . :tazz:
