Creating a tree

[Sasquadge]

Hey guys I'm running into an error. I've got the tree and the base working. But now that I'm to the trunk it'll only center the first one and the rest are to the left. any suggestions?

#include <iostream>
using namespace std;

double height;

int main()
{
    cout <<"This program will take a height and create a tree.\n";
    cout <<"Enter your height (3-15): ";
    cin >> height;

    if (height < 3 || height > 15)
    {
        cout << "The number you entered is not between (3-15). Try again." << endl;
        return 0; 
    }

    //This will build the tree.

    for (int level = 0; level < height; level++)
    {
       for (int spaces = 0; spaces < height - level - 1; spaces++)
           cout << ' ';

        for (int a = 0; a < 2 - 1; a++)
           cout << '/';
        for (int middle = 0; middle < 2 * level; middle++)
            cout << ' ';
          for (int b = 0; b < 2 - 1; b++)
              cout << '\\' << endl;
    }  

    //This creates the base.

    {        
        for (int middle = 0; middle < 2 * height; middle++)

            cout << '-';
            cout << endl;
    }   

    //This creates the trunk.

    {
        for (int middle = 0; middle < height - 1; middle++)
           cout << ' ';

        for (int middle = 0; middle < 0.5 * height; middle++)
            cout << '|'<< '|' << endl;


    }
    return 0;
}

The last two loops should be nested:

for (int middle = 0; middle < 0.5 * height; middle++) {
    for (int middle = 0; middle < height - 1; middle++)
        cout << ' ';

    cout << '|'<< '|' << endl;
}
