const string array to a int array

[Lazysquirell]

Ok so I am back in school and it has been to long since I have used c++ I can not find or figure out how to convert a char array into a int array so i can add numbers really large numbers. the string is being passed into the function as a const char* and help would be greatly appreciated, unfortunate I think I will be here often seeking guidance.
thanks in advance

You can use atoi, stringstreams, and/or third-party sources such as boost coerce_cast.

I think i got it, I actually just copied it into a int array and set a simple subtraction function.
