rappel intro
Rappel is a wonderful for understanding the basics of assembly language. Initially assembly language is quite challenging to understand for the programmer as all these registers are quite confusing. Specially it becomes more difficult because the programmer is now limited to using only handful of variables where as in other languages, the number declaring variable appears to be unlimited.
After we download and run the rappel, we can see that
$ ./rappel
rax=0000000000000000 rbx=0000000000000000 rcx=0000000000000000
