Lesson 17 - C and C++ libraries New

Libraries are an important part of programming. They contain a set of functions and structures that are closely related. In the compilation article, we said that the linker merges files and recalculates the offsets of individual calls. However, the real role of the linker is to connect our application to libraries. When a linker encounters the use of a library, it basically has only two options. It can either copy the code from the library to our application or make the necessary functions available while the application is running.

The difference between a static and a dynamic library

The static library is the result of the first approach. The compiler copies the source codes from the library and places them among the codes of our application. Static libraries usually have the file extensions .a (for Linux) or .lib (for Windows). Dynamic libraries are not added to our source file, but are attached to the application at runtime. This leads to several problems, which we'll talk about later. To use a dynamic library, we must
