Lesson 16 - Compilation in C and C++ - continued New

In the last lesson, Compilation in C and C++, we talked about preproccessing and compiling into object files.

In today's work, we'll look at linking and talk about why C uses header and implementation files.

Linking

When compiling to object files, we said that the compiler doesn't know if the function call exists and where it is. The use of the correct addresses in memory is solved by the linker. There are no longer any function names in the final executable file. The function starts at some address in the memory (offset), from which the instructions start executing until the processor encounters the ret instruction. It takes the last record in the stack and returns to the memory location specified by the retrieved value - as we saw in the previous episode. As a reminder, I am once again attaching the source files from the last lesson.
