I'm trying to take a string of numbers and convert it to an actual number. I can successfully convert it if it's just one digit, but I'm unsure how to convert a number with two or more digits.
section .data
str: db '3' ;string to be converted
section .text
global _start
_start:
mov ebx, [str]
sub ebx, 48 ;convert character to number
mov eax, 1
int 0X80 ;exit, returning the converted numberJump to Post123
First loop is 1
Second loop is 1*10+2
Third loop is 12*10+3
123
First loop is 1
Second loop is 1*10+2
Third loop is 12*10+3
Ok, now I have another problem. I can easily access the second number in the string using mov eax, [str+1] However, this number can't be looped, so I try to do the same thing only using a register, which doesn't work. Does anyone know how to do this?
Thanks!
You put the address of the string in a register, then increment the register.
