Calls, Strings and Codes Course

Learn how to do basic input and output, work with strings and condition codes at the x86 Assembly level. Then try your hand at your first project by building your own x86 Assembly program.

1 hour, 16 minutes

Course description

In this course, we'll learn how to do basic input and output (i/o) operations at the assembly level, including how to store and work with strings. Then you'll try your hand at your first project of building an application written entirely in x86 Assembly. Finally, we'll look at condition codes and how the x86 processor handles tracking the state of certain processor conditions.
