Review compilation principles (1)

After coding is complete, whether it can correctly achieve our expected goal, we must first compile the Code through the compiler, that is, our encoding is at least syntactically correct. The so-called correct syntax means that our code must comply with the syntax rules of the language in use. The essence is that the compiler can correctly parse the code to get the target code to be executed on the machine. Sometimes, compiling is just the beginning, and we will find that the program results are

A Brief Introduction to ARX

Developers who do not know about CAD may not know this information.

The secondary development of CAD is based on this. writing ARX programs is actually using DLL (dynamic link library). This dynamic

you make a mistake, you should acknowledge it quickly. It is another common mistake to understand the compiler error information. If you don't understand a compilation warning or you think the time is too short to check, do you think this is a real waste of time? The compiler clearly shows you the problem, but you don't try to solve it. I have met many people who have asked for help during the debugging process, I asked them if they had a good compiler. They answered yes. As a result, I began t
