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: 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.
