C and C ++ memory mechanisms are different
Although the memory mechanism of C and C ++ is very similar, there are still some differences.

Extern "C"When using C functions in the C ++ environment, the compiler often fails to find the C function definition in the OBJ module, resulting in a link failure. How can this problem be solved?Answer and analysis:

First, the preferred creation of a C DLL project, production DLL files used for standby, steps are as follows:

In recent projects, project source code confidentiality issues are involved, because the code is written in C #, easy to decompile, so the decision to extract the core algorithm part of the use of C + + writing, C + + so far seems to have not been very good decompile, of course, if you are a disassembly master, perhaps it is possible to decompile. This means that

When developing C/C ++ programs on different platforms, in order to avoid garbled source code files, we have to use UTF-8 encoding to store source code files. But many compilers have poor compatibility with UTF-8 source code files, so I did some tests and analyzed the best saving solution.I. Test Procedures
To test the compiler's compatibility with UTF-8 source code files, I have compiled suc
Item m34: how to mix C ++ and C in the same program
For many years, you have been worried about using C ++ in part during programming, just as using multiple compilers to generate programs in the age of all C programming. There is no way to program Multiple compilers, unless different compilers have the same implementa
The beauty of code is not just finding solutions for a given problem, but also the simplicity, validity, compactness, and Efficiency (memory) of the code. Code design is more difficult than actual execution. Therefore, every programmer should remember these things when programming in C language. This article introduces you to the 10 ways to standardize your C code.
