Adding Numbers to Memory Cells

Explore how to perform addition of numbers stored in memory cells by translating C operations into assembly language. Understand the limitations of x64 instructions requiring register use and learn to interpret GDB disassembly output to analyze memory and register changes during execution.

We'll cover the following...

Now let’s look at the following pseudocode statement in more detail:

(b) + (a) -> (b)

Remember that a and b are the names of addresses (locations) 000055555555802c and 0000555555558030, respectively. The ...
