I've got the initial part but....

Code:

---


#include <iostream>
using namespace std;
#include <conio.h>

int main()
{
        int n;
        int x=1;

        cout << "Please ask for nonnegative integer: ";
        cin >> n;
        cout << endl;
        while ((n > 0) && (x != (n + 1)))
            {cout << x << " ";
                  x++;}
                if (x = n)
                      n--;
                else
                    { cout << x << " ";}
              cout << endl;
    getch();
    return 0;
}

I'm supposed to write code that will accept a positive integer 'n' and display (ie if integer is 7):
1 2 3 4 5 6 7
1 2 3 4 5 6
1 2 3 4 5
1 2 3 4
1 2 3
1 2
1

I get the first line to print out but am a loss to get the rest of it to print.

Suggestions please!!!

You'll need a double loop, the inner one increases x and the outer one decreases n.

You need to use nested loops, i.e. a loop within a loop. The outer loop will control how many lines you write out (7) and the inner loop will print the values 1-X.

Thanks for the help!

I finally have it. Though it may not be very elegant, it still works. Suggestions welcome for cleaning it up.

Code:

---

#include <iostream>
using namespace std;
#include <conio.h>

int main()
{
        int n;
        int x = 1;
        cout << "Please enter a nonnegative number: ";
        cin >> n;
        while (n > 0)
                {{x = 1;
                n--;
                cout << endl;}
                        while (x != (n + 2))
                        {cout << x << " ";
                        x++;}}
        cout << endl;
        getch();
        return 0;
}

    cin >> n;

    while (n > 0)
    {
        x = 1;
        while ( x <= n )
            cout << x++ << " ";
        cout << endl;       
        --n;
    }

    cout << endl;
    getch();

    return 0;
}
