    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;
    }
