I found an online platform for creating programs called Hicalc at “http://www.hicalc.com” Does anyone know if it is easy to write programs for this site?
you can ask someone elso to help in first steps of programming, as they say You can create program with almost all C# 4.0 syntax (.NET and c# programming experience), people are classified into two groups: one are programmers creating programs with C# 4.0 and share with other people, the others are users who use the programs to calculate.
Your program must be valuable and get at least 50 approvals with Google +1 button (There is a Google +1 button on every program page) within 2 months
Whether it's easy, is subjective as it depends on your programming background. I suggest you learn C# (C Sharp) which will make using their public API and libraries much easier. I've posted some learning resources below.
MSDN - C# Programming Guide
I'll be making a programming in C# series on YouTube sometime soon, I'll update this post once I've begun.
