Develop your own calculator (1)-Prepare the development environment

This time, we use C ++ for the development language and Qt for the development environment. There is nothing to explain when selecting C ++.

Why Qt is selected

• Qt is free of charge
• Qt is a cross-platform development that can be released on multiple platforms, such as Windows, Linux, and Symbian ).
• Popular technologies (such as Layout and XML) and architectures used in Qt development. After learning Qt, it is easier to get started in other environments.

Installation Steps

Qt has done a very good job in this regard. The installation steps are simple. Visit qt.nokia.com/downloadsto choose the appropriate operating system and the installation method for direct installation.
