1) First, a simple calculator is computed using C # process-oriented Code. The Code is as follows:
Try {console. writeline ("Enter the number A:"); string numbera = console. readline (); console. writeline ("Enter the calculated character" +,-, *,/""); string operater = console. readline (); console. writeline ("Enter the number B:"); string numberb = console. readline (); double strrusult = 0; If (operat
Use java to create a simple calculator-general Linux technology-Linux programming and kernel information. The following is a detailed description. There are two classes in total. It only completes the +,-, X, and merge operations.
The GUI only uses AWT, which is easy to understand.

As a friend in the jealousy group wrote a calculator, I made a special use of the simple factory model "coffee" I just learned. It felt so cool !! The emergence of the object-oriented design model is to save my messy code. Looking at my previous "Book of heaven", I feel impulsive !!!
The calculator mode is very simple

The design pattern is the goal of refactoring. It plays an important role in code reuse and expansion. The importance of restructuring and design patterns is self-evident in learning object-oriented models. Then, the learning design model should be combined with software design and software coding, and driven by examples. This article
