ASCII Triangle
Hi,
I need to create a triangle based on a height value given by the user.
The base of the triangle is calculated with:
Java Code:private int getTriangleWidth( int triangleHeight ) { return 2 * triangleHeight  1; }
Java Code:private void printTriangle( int height, int margin, boolean pointUp ) { int base = this.getTriangleWidth( height ); int m; int n; int o; if( pointUp ) { for( n = 0; n < height; n++ ) { for( m = 1; m <= margin; m++ ) { System.out.print( " " ); } for( n = 0; n < height; n++ ) { for( o = 1; o < n; o++ ) { System.out.print( "*" ); } System.out.println( " " ); } } }
*

but I need an equilateral triangle: if the user inputs 5, it should have a base of 9 and a height of 5 and it should not have a right angle as the one above.
I understand that in my code above I don't have it depending on the base value at all but I'm not sure how to include it in or how to get the whitespace to come before the * in an even way so that I get my desired result.
Any hints would be wonderfulLast edited by physics; 03122010 at 11:32 PM.

Here's a clue, you can use the getTriangleWidth(int) method to return the number of stars needed for each level of the triangle.
You aren't even using that method yet...
