How to write portable code in c++?

Question

What are the things that I should keep in mind to write portable code? Since I\'m a c++ beginner, I want to practice it since beginning.

Thanks.

Write command-line programs to begin with. When you're ready, find a cross-platform windowing toolkit such as Qt.

If you're interested in writing multilingual code, use a third-party unicode library such as ICU rather than relying on platform-specific libraries.
