    Read only memory

    Code:
    char *quote = "Live long and prosper";
    char expression[] = "Illogical";
    
    quote = expression;
    Initially quote pointed to read-only memory. When I reassigned the quote to point to expression, what happened to "Live long and prosper"?
    I know I lost the handle to it. Would that be considered a memory leak as well as with dynamic memory?
    It can not be freed before the reassignment, since it doesn't reside where dynamic memory is allocated.
    Would that memory be reused again? What doth say ye?

    If the memory had been dynamic, then yes it would have been a leak. In this case, it's part of the data stored in the program itself, so it cannot be reused for something else (until your program exits).
