The mode string can also include the letter 'b' either as a last character or as a character between the characters in any of the two-character strings described above. This is strictly for compatibility with C89 and has no effect; the 'b' is ignored on all POSIX conforming systems, including Linux. (Other systems may treat text files and binary files differently, and adding the 'b' may be a good idea if you do I/O to a binary file and expect that your program may be ported to non-UNIX environments.)

A *a = new B;удалиться ли из кучи b, поскольку он выходит за пределы размера A, поскольку в этом месте компилятор не знает, что он работает на самом деле с B… Или где-то еще храниться информация о размере этого экземпляра? И не будет ли в этом случае утечки памяти? Спасибо ☺️
//Тип В явно больше А на один байт. Так вот… Если я сделаю так:
delete a;
