Question

I want to apply << shifting operator on character pointer and want to increase value of this at some position.

For example: char *p;

In *p, i want to apply left shifting on some specific position *(p+i) << 1 and ++ increment operator on specific position like *(p+i)++

Answer 1

I’m not really sure I understand what you want to do, but if you want to do:

*(p+i) = *(p+i) << 1;
*(p+i) = *(p+i) + 1; //++

You can rewrite them as:

*(p+i) <<= 1;
*(p+i) += 1;
