Calculator In C# With Source Code

This calculator program is a windows C# application programmed in Visual Studio. It’s essentially a basic Windows calculator re-coded from scratch, with a few functions of a scientific calculator. This Calculator program can be really useful for students or people who want to see how the “engine” code is separated from the GUI in a program. Calculator C# can perform anything the Windows Standard calculator can do.
