Le me throw in my 2p too...

Putting a+b as a - ( -b ) is not impressive. See this:

for(i=0;i<b;i++){
    a++;
}

OR

while(b){
    a++;
    b--;
}

and put these marvels in a class:

class intAddNoPlus
{
/* blah */
    int a,b; /* our VIPs */
    public:
    int add()
    { 
        /* Select your favourite algo and return */
    }
};
