How do you format an unsigned long long int using printf?
...inttypes.h library that gives you types such as
int32_t, int64_t, uint64_t etc.
You can then use its macros such as:
uint64_t x;
uint32_t y;
printf("x: %"PRId64", y: %"PRId32"\n", x, y);

What does default(object); do in C#?
...he requested type.
For all reference types (defined with class, delegate, etc), this is null. For value types (defined with struct, enum, etc) it's an all-zeroes value (for example, int 0, DateTime 0001-01-01 00:00:00, etc).

What's the most efficient way to erase duplicates and sort a vector?
