x86-64 Assembly Pointers & Dereferencing Explained – Hybrid C++/YASM Example

This video explains pointers and dereferencing in x86-64 YASM assembly and demonstrates passing pointers between assembly and C++ in a hybrid program. We show how to read a C string from assembly, modify a long via pointer dereference so the change is visible in C++, and send assembly-owned data (string, long, double) back to C++ using pointers.

x86-64 Assembly While Loops Explained Step by Step in YASM – From Concept to Working Program

This video teaches how to implement a classic while loop structure in x86-64 assembly language using YASM. We cover the conceptual mapping from C-style while(condition) { body } to assembly labels (while_top, while_body, while_done), conditional jumps (jne, je, etc.), and the unconditional jump back to the top of the loop. A complete runnable example repeatedly reads integers from the user and echoes them until 99 is entered.

x86-64 Assembly: Integer Data Movement, Pointers, and Dereferencing Explained (YASM on Ubuntu)

This practical x86-64 assembly language tutorial explains integer data movement between registers and memory, the importance of data size specifiers (byte, word, dword, qword), the difference between pointers and dereferenced values, pointer arithmetic for array access, and using LEA for address calculation - all demonstrated with YASM on Ubuntu Linux and inspected via GDB.
