5,148 PointsIndex was outside the bounds of the array
Please help me with this exercise. I got the error "Index was outside the bounds of the array" even when I removed the equal sign in the for loop condition. Thanks!
namespace Treehouse.CodeChallenges
{
public static class MathHelpers
{
public static int[][] BuildMultiplicationTable(int maxFactor)
{
int[][] table = new int[][] {};
int i;
int j;
for ( i = 0; i <= maxFactor; i++)
{
for ( j = 0; j <= maxFactor; j++)
{
table[i][j] = i*j;
}
}
return table;
}
}
}

Also, when creating jagged arrays, you create the master first with a single dimension, then each element will get another one-dimension array. Both the master and the "row" arrays will need to be sized appropriately when they are created.

5,148 PointsThe requirement of the exercise: "Return a multiplication table consisting of an array of arrays. The table should contain all of the products of integers from 0 to maxFactor."
