    Specify a pointer to the variable that you want to change. That should do the trick.

    To code, or not to code, that is the question.

    Well the answer is 'TO CODE' of cause

    You can only assign an address of a constant to a pointer to a constant so that wouldn't work. You can cast though -

    const int a = 10;
    const int* ptr = &a;
    *(int *)ptr=20;

    Why make it const if you are going to want to change it? You are better off just being careful not too fool with it too much.
