Adding two octal numbers from char[] C language

[kamilosinio]

Hi, I'm on the end of my project and I have to add two octal numbers. I have got them in the char array and I'm stuck. Can you give some advice how to do this?
I tried add 0 as a frist element (adding in octal, so need 0) of arrays and use atoi, but that gives me integers without this 0.

You have two numeric strings in octal and want to add them so as to produce a numeric string in octal? I'd suggest using strtol, and then finish off with sprintf (or if available, snprintf).

Hey maybe a little correction, arrays looks like num1="12345677", num2"12345677"

"You have two numeric strings in octal and want to add them so as to produce a numeric string in octal?". Yeah, excatly.
Okey, I will try, thanks a lot.
