Finishing my "int class"... help with weird operator overloads

This class stores the data as a string, but the operator overloads make it act like an integer. Problem is, I'm not quite sure how to go about doing this with the remaining operators. They're listed at the bottom of the post.

I need 4 possibilities each (these are already completed): (i.e.: a+=1 means a = a + 1 )

const ooint & operator += ( const ooint & str ); // add str to CString
const ooint & operator += ( const char * s); // add str to CString
const ooint & operator += ( char ch ); // add str to CString
const ooint & operator += ( int rhs );

Something like that, but I still don't have it figured out.

Operator/Operation Performed
&= Bitwise-AND assignment
|= Bitwise-inclusive-OR assignment
^= Bitwise-exclusive-OR assignment
++ Increment operator
-- Decrement operator

I need all of those with 4 each (all possible combinations), and I have no clue how to go about some of them because I don't know how they work.

operator overloading... I'm stuck has more information on my class if you need it.

How your overload the operators is up to you. For example, what do you want %= to do specific for your data type?

Inside the class, it is stored as a string. Outside the class, it acts like an integer except it allows you to use []

ooint c = 0;
char string[] = "100";
c = c + 5 + string;
cout << c << skip;

that gives 105.
So does this:

ooint c = "0";
int integer = 100;
c = c + 5 + integer;
cout << c << skip;

I want the remaining overloads (see the first post) to do what it would normally do with an integer or a string, depending on what data type it normally is used with. I want %= to do what it does for integers, that part is easy, but I need % in order to do that... 5%2=1

Also, I need ++ and --:

ooint c = 5;
c++; //add one to 5
c--; // subtract one from 5

[EDIT]%= Remainder assignment
% Modulus operator

I figured out those... those ones were obvious[/EDIT]

Also, with +, -, *, /, and % operators, I can't add a character like this:

ooint a = 0;
a = 1 + '3';

because I can't declare it in the class without it having a member of type ooint.
