Finding Sum without using + operator

[Tapan Sharma]

Hi,
I want to do the following:

int a = 10;
int b = 2;
int res = 0;
char *op = "+";

// now, without using + operator in the next coming lines,can i get the sum
// of a and b like in following way:

res = a op b;

or in any other manner using 'op' instead of '+'.
Can we do this?

No, the compiler isn't going to like that.

Is this some kind of assignment where you have to find a sum without using +?
