Question

I have a bit that I am toggling in my program, and was wondering if I can do this:

    char *toggle = // some address;
    *toggle = 0; // initially

    // if(something)
    //    *toggle = 1;

    // other code that continues to toggle under certain conditions...

But dereferencing a char* treats the value like a char, nothing more and nothing less. So I was wondering if it is a valid method of storing the 1 and 0 (which are integers)?

Answer 1

Yes, that’s a completely valid method. char can be treated like an integer in most cases – and as such you can also do arithmetic on variables of type char.
