Software Design for handling key data changes in programs All problems encountered in the project can be summarized as follows: 1. Local logic field control 2. Local Transparency of the field Logic 3. All commands are passive. When the sub-board is in a subordinate position, the commands transmitted between the sub-board and the master control are actually only a control signal transmission. All functi

Defining variables is essential when writing programs, and some basic data types are used. Perhaps you would say that it is easy to define a variable with any difficulty. To define an integer variable, use "int i;" directly. statement, and to define character variables, use "char C;" directly. It's OK. Indeed, this is what school education teaches us, but it cannot be done in practical work. Why, then? The reason is simple, because the program is wr

Comments: If you save valuable files on your laptop, you certainly know the importance of protecting the data. However, knowing that something should be done does not necessarily mean that it is being done, because a large number of reports every day indicate that sensitive data of many companies is lost or stolen from their laptops. However, protecting data secu
