How can I write a program for cubic spline?

Hello!

How can I write programs for

• natural cubic splines
• periodic cubic splines
• Hermite cubic splines?

I do not have any data, so am I allowed to just take some data?

I should take xi, i = 0,..., n+1 with

yi, i = 0,..., n+1

and determine the moments Mi
