I learned in the class that we can use pointers in assembly with these brackets []. but in my program that dosent work and give me 'wrong parameters error'. will be very happy if you help me :)
cmp [cx], num
JNE LOOP1
inc count
jmp LOOP1
how you can see, i try count number of "num" in an array, and there is problem with the first line
Simple answer: x86 assembly doesn't support two explicit memory operands in one instruction.
So your first instruction cmp [cx], num is invalid. Load one of the arguments into a register first, and then execute the comparison (for example, like this):
mov ax, num ; preferably outside the loop
cmp [cx], ax
JNE LOOP1
inc count
jmp LOOP1
This should fix that problem.
[cx] isn't a valid 16-bit addressing mode either, so pick BX, SI or DI instead for iterating a pointer over the array.
I get it, the problem was that I made cx a pointer, but the only bx, di and si can be pointers. so now my code looks like this :
mov bx, cx
cmp [bx], ax
JNE LOOP1
inc count
jmp LOOP1
