Tutorial for Pascal/Delphi for C++-Coders

It shouldn't be too difficult to pick up. C's design was influenced by ALGOL and Pascal, so the semantics and logical flow are going to be pretty familiar. You can get an overview of the differences between basic Pascal and basic C here.

But you tagged this as Delphi and you mentioned C++, which implies that you'll need information on OOP techniques. Try this article or this one, which compare object-oriented programming in Delphi with C++ and other languages. Both are a bit dated, but most of the basic information in them still applies today.

If you have any specific questions about language features, feel free to ask them here, and welcome to Stack Overflow!

You can check Essential Pascal written by Marco Cantù, is a introduction to the Pascal programming language. you can download a free copy from here.

Another excellent site for beginners, is Delphi Basics, this web site provides help and reference for the fundamentals of the Delphi language. It gives an introduction to the Delphi Object Oriented Language for newcomers.

A website that helped me a lot when I learned Delphi was http://www.delphibasics.co.uk/. I still use it. It presents common methods in a nice way.
