On a 64 bits architecture, what does the following code print ?

  const char* s = "123456";
  printf("%zu\n", sizeof(s));

Note: "%zu" is indeed the correct way to print values of size_t type.

Nothing, it does not compile.

Some unknown value that cannot be determined from the provided informations.

Another (known) value, different from the above proposed propositions.

What does the following code excerpt print?

  int tab[] = { 2, 4, 6, 8, 10, 12 };
  putchar('1');
  int a = -1;
  int* p = tab + 2;
  while ((a = *p++) < 10) { printf("%d", a); }

Considering

False, it's tab[1][4] which comes in memory right after tab[1][3].

The question does not make sense since tab[1][3] in not valid syntax.

False, it's tab[2][3] which comes in memory right after tab[1][3].

True.

False in general (it can be, but this is not ensured).
