For historical reasonsCodeIt is not entirely written using. net. At this time, mixed programming with the previous C ++ code is very important. I recently encountered such a problem and briefly described the method as follows. Call simple C ++ Functions The general idea of calling C ++ functions in

Otherwise, the constructed dynamic link library does not have the symbol tables of these functions. ImportCtypesso = ctypes. CDLL ("./libtest. so") so. display () so. display_int (1) The running result is as follows:^ [Root @:~ /Projects/nugg

Readers may suspect that something as simple as an if, a for, a while, a goto, or a switch should also be about programming style, is it a fuss? I really find that many programmers write expressions and basic statements in the wrong way, and I have made similar mistakes myself. Both expressions and statements belong to the C++/C phrase structure syntax. They se

if the global variable is to be referenced, it is placed in the *.h and declared with extern. 2. If the declaration of a function has a keyword extern, it simply implies that the function may be defined in another source file, with no other effect. That is, the following two function declarations do not differ: extern void Print_externifo (); and Voidprint_externifo (); The use of extern in functions: If the C/cpp file that defines the function d

The diagram shows a framework for how to organize memory in a typical C + + program. The instructions in the program (which are stored at the bottom level) and global variables are often stored statically (static area), which is located at the beginning of the near machine address space where the address number is smaller. The amount of memory allocated in the zone does not change during program operation.The highest address area in memory represents

automatically executed, it is equivalent to the root of the tree. If some rules are not in this tree Not automatically executed. For example, the Clean Action in the example above (these actions can be called) 6. Write outstanding makefile filesWriting makefile does not mean writing a beautiful makefile.Variables (equivalent to macros) in makefile: Name =... reference $ (name)The purpose of using variables makes makefile clear and easy to maintain. 7.

When using C + + programming, sometimes to use the third-party library, and the first party libraries is given in C, it is strange that the C file has been added to the project, the header file has been introduced, the compilation still appearsUndefined referenceThe problem here, the third party
