What happens before your code even runs?
The sources collectively offer a comprehensive look at the execution of computer programs, focusing on the stages before and during runtime. One source explains that the actual entry point for most C/C++ programs is the _start function, which handles low-level setup and runtime initialization before calling the user's main function. The other sources provide extensive detail on the linker and loader processes, which prepare executable code by resolving symbolic references, performing relocation (adjusting addresses), and managing memory segments (such as text, data, and BSS). They also contrast how compiled and interpreted languages function, discussing advanced techniques like shared libraries, dynamic linking, and the complexities of language-specific features like C++ name mangling and the unique loading model of Java class files.
