I. Preface
The computer (calc.exe) Program has existed for a long time in windows and is also a very common software. But in general, it displays Arabic numbers, and there is no switching between character display. This time I will discuss in two articles how to make the calculator program display Chinese characters and numbers. This article discusses the basic principles of modification, and the next article discusses how to implement programming.
