Notes on reverse engineering in Russian for beginners, for those who want to learn how to understand the code created by C++ compilers for x86x64, ARMARM64, MIPS, JavaJVM architectures. The term "reverse engineering" has several popular meanings: 1) the study of compiled programs; 2) scanning the three-dimensional model for subsequent copying; 3) restoring the structure of the DBMS. This collection of notes is associated with the first value. When the author of this book taught C and then C++, he just wrote small pieces of code, compiled and watched what happened in assembler. It was so much easier to understand.
