Assembly langauge

RedXIV

hey i'm playing around with assembly language here as a complete noob to it. just wondering if anyone could tell me how to count the number of times a loop runs, the program just takes numbers you enter and is supposed to tell you how many after wards. i'm just confused if you use the cx register or should you assign a new variable for it?

cheers

it reallt depends on what assembly language you are using and for what chip.

but the general idea would be to use a register as a counter and this would be incremented each time the loop runs

Smellyirishman

xor ax,ax
mov bx, userVariable

loop:
inc ax
dec bx
jnz loop

end

Something like that, assuming your using x86 stuff. Of course, I am not sure if you take in a sentinal to end the loop or if you take in a single number representing how many times to loop? I think it may be the first , in which case the code is off base, but the loop counting element is consistant.

Of course, as the above poster said, it all depends on your language , output, etc...

The above should work fine then. Output will vary, depending on your medium.
