[C + + advanced path] three methods for C + + to prevent header files from being repeatedly introduced!
Previously, we introduced in detail how to use macro definition (#ifndef / #define / #endif) in C language to effectively avoid repeated #include of header files. This method is also commonly used in C + + multi file programming. For example, the following is a C + + project with school H and student H […]

C + + loop! Loop type + loop control statement + infinite loop!
C + + loop Sometimes, you may need to execute the same piece of code multiple times. Generally, statements are executed sequentially: the first statement in a function is executed first, followed by the second statement, and so on. Programming languages provide a variety of control structures that allow more complex execution paths. Circular statements […]
