Does someone know how to swap the values of 2 registers without using another variable, register, stack, or any other storage location? thanks!
Like swapping AX, BX.
You can do it using some mathematical operation. I can give you an idea. Hope it helps!
I have followed this C code:
int i=10; j=20
i=i+j;
j=i-j;
i=i-j;
mov ax,10
mov bx,20
add ax,bx
//mov command to copy data from accumulator to ax, I forgot the statement, now ax=30
sub bx,ax //accumulator vil b 10
//mov command to copy data from accumulator to bx, I forgot the statement now
sub ax,bx //accumulator vil b 20
//mov command to copy data from accumulator to ax, I forgot the statement now
