While Loop does not have an output

Dear FIB + Others,

I have typed the while loop as mentioned in the book "OOP in Turbo C++" by "Robert Lafore".

I am supposed to get a prompt to input and and an output of what I typed. However, there is no cout << variable mentioned in the book.

Code:

// demonstration of while loop
// as typed in the Bloodshed IDE

#include <cstdlib> // winxp terminal handling lib
#include <iostream>

using namespace std; // may be something to do with winxp > terminal

int main(int argc, char *argv[])  // win Xp terminal arguments
{
    unsigned int i = 1 ;      
    while(i != 0)
    cin >> i;
   
    // Win XP terminal calls
    system("PAUSE");
    return EXIT_SUCCESS;
}

Did I miss anything? Thanks in anticipation.

Best Regards

What your program is doing is this..

It sets i = to 1, then the while loop checks to see if I is not equal to 0 and it executes the line after that while I is not equal to 0, so it should keep asking for input. Also..there is no cout to print the output.

Code:

#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
    unsigned int i = 1 ;      
    while(i != 0) {
    cin >> i;
    i--;
}
   
    cin.get();    
    return EXIT_SUCCESS;
}

Try not to use system(), it is a bad command and should be avoided, search the boards if you want to know the details of why it is bad.

Code:

cout << "hello world" << endl;

Just change the words to suit what you want them to say?
