TCPPPL Chapt 7 : Pointers

As a former C programmer (as a student), this seems to be a familiar topic to me : really, the only thing you need to learn about C is pointers. However, people like me need to be aware of certain things.

void *. The book mentions that void * must be explicitly converted before it is assigned to a certain pointer type. I can’t remember that if you can use it without cast in C. Anyway, this is the reason why nullptr is better than NULL, according to the book. ( NULL may be macro of (void *)0 ). read more

Apparently this chapter is like a law book. I will left this as a list and I will finish this later when I finish this book.

Implement defined features, unspecific, and undefined

Hosted vs Freestanding implementation

int/pointer to bool

char impl defined signed/unsigned : ok to convert to unsign ed

int{c} construct int from a char

3digit octal

multicharacter literal

Unicode
