What is the relation between word length, character size, integer size, and byte in C++?

The size of numeric types is generally a multiple of the machine word size.....
It follows for those values of depends on what you mean by relation .
size 2^14 on any platform, because that is less than 2^15-1 of course.

Why is it recommended that the swap partition size be double that of the RAM size?
Specifically, why would I need to store data stored in the RAM twice??

You'll need minimum 1 X your memory size if you suspend-to-disk (hibernation), and add enough spare for usage of 'swapped' memory which goes....
Swap partition having double the memory size is just a general guideline, not a hard and fast rule.

I don't get why I get 0 when I use printf and %d to get the size of my vector:
vector<long long> sieve; int size; ... //add stuff to vector ... size = sieve.size(); printf("printf sieve size: %d \n", size); //prints "printf sieve size: 0" std::cout...

What's the hardware you're running on? Odds are that size is a different type than you think.
Couldn't say why printf isn't working, though.
Vector sizes are size_t , which I believe is usually a long ...

Recently I've noticed that the following statement is not true given std::string s .
s.max_size() == s.get_allocator().max_size();
I find this interesting, by default std::string will use std::allocator<char> which has a theoretical limit of size...

Customers may be depending on our current behavior, and (2) max_size() fundamentally doesn't buy anything such chunk is then limited to std::allocator::max_size() but the sum may be larger than that.

Hi guys.
Is it possible to have an UIView with its bounds size different of its frame size?
I'm trying to create an UIView with "{{0,0},{320,367}}" frame and "{{0,15},{320,337}}" bounds but i can't get it done using setBounds() and setFrame().
I got from...

The bounds is at (0,0) while the frame (and center) give the view's position .

Say I have an algorithm which operates on an input of size n and I know that the time it takes for n is twice the time it takes for n-1. I can observe in this simple case (assuming it takes, say, 1 second for n = 0) that the algorithm takes 2 n seconds...

Master Theorem
In particular:
With T(n) = aT(n/b) + n c
If log b a < c, then T(n) = O(n c )
If log b a = c, then T(n) = O(n c log[n])
If log b a > c, then T(n) = O(n log b a )
That's one useful theorem to know, but doesn't fully answer your question... .

Is it worthwhile to initialize the collection size of a List<T> if it's reasonably known?

It is, as per documentation
If the size of the collection can be estimated, specifying the initial to be a particularly large list and you've got a pretty good idea of the size, it won't hurt.

The image dimensions being multiples of 8 or 16 is not going to affect the size.
Need to pad three lines and line X is the edge, line X+1 is equal to line X, line X+2 is equal, such as in video compression.
