John: Take a look.  https://chihaukam.blogspot.com/2026/01/john-have-look_8.html?m=1 . It say, "Left shifting and stack overflow isn't the principle of hacking. ". See the picture above.  R0 and R1 are 2 independent registers. They have 4 bits.

.

Me: If they have 4 bits only, there's a problem.  If I wanna do that, 

For (int I = 0; I < 8; I ++){}

.

Me: How can I do that?

John : When you press a button,  your code change into

.

For (int I = 0; I < 4; I ++){} <--- R0

For (int I = 0; I < 4; I ++){} <--- R1

.

Me: Who does change it?

.

John : The system change it.
