Floyd's triangle and Pascal's triangle

Project #1

Create an Interactive program to display a Floyd triangle.

The number with the largest number of digits determines the width of each column to display. (Use a monospace font?)

For example (2 digits)

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

Project #2

Create an Interactive program to display a Pascal triangle.

The number with the largest number of digits determines the width of each cell to display. (Use a monospace font?)

Project #3

Ask the user which number to start with. (Something other than 1?)
