Creating an X shape

[Zaywop]

I need some help with a homework problem. The question is asking me to create an X
shape with decrementing numbers.

/* The Output should look like this
5   1
 4 2
  3
 4 2
5   1

or

7     1
 6   2
  5 3
   4
  5 3
 6   2
7     1
*/
but so far I can only get a V shape. 

int main(int argc, char** argv) {
    int n;
    int x;
    
    cout<<"Enter an integer between 1-50.\n";
    cin>>n;
    
    if(n%2==1){ //loop for odd integers.
        x = n;
        for(int i = 1; i <= n; i++){
            cout<<setw(i)<<x<<setw(2*x)<<i<<endl;
            x--;
        }
    }else{  //branch for even integers.
        
    }

    return 0;
}

/*Right now my output looks like this:
5         1
 4       2
  3     3
   2   4
    1 5
*/

I'm having a hard time figuring out how to get the lines to converge at the middle number then diverge out.

Hi,
Not very sure, but can you please try this line :
cout<< setw(10 + i*2) << x < <setw(10 + 2*x*2) << i << endl;

[Naughty Albatross]

Or :
cout<< setw(5 + i*4) << x << setw(5 + 2*x*2) << i << endl;

[Zaywop]

Nope that basically does the same thing I did with the formatting.

Or maybe you try this then :
cout<< setw(5 + x*4) << x << setw(5 + 2*i*2) << i << endl;

If all else falls, you may consider using the alternative. Try this function :

#include <windows.h> 
void gotoxy(int x, int y)
{
  COORD coord;
  coord.X = x;
  coord.Y = y;
  SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord);
}

And :

gotoxy(5 + x*4);
cout << x;
gotoxy(5 + 2*i*2);
cout << i;

Does that help you? :)

[Zaywop]

I probably shouldn't use that since the assignment requires me to use only for-loops and the iostream library.

[Naughty Albatross]

Maybe this will be sufficient :
cout<< setw(8 + x*4) << x << setw(8 + 2*i*2) << i << endl;
