In C++, are bitsets actually a set of bools? Doesn't this defeat the purpose of using a BitSet because bools are 32 bits (I think...)?

I want to learn C++ by using Vim and MinGW as compiler. I'm interesting at "C++ Primer (4th Edition)" and "C++ Primer Plus (5th Edition)" but I don't know how about it different. It has no book store that I can review those books, so I want to know, what is the different between those book and which…

Ok, so I don't want you to do my homework for me, but I'm a little lost with this final assignment and need all the help I can get. Learning about programming is tough enough, but doing it online is next to impossible for me... Now, to get to the program, I am going to paste what I have so far. This…

Prototype : void read ( const std::string &imageSpec_ )
I call this function from managed c++ dll by passing a std::string.
When i debug the unmanaged c++ code the parameter imageSpec_ shows the value correctly…

After more than a few questions about deciding on C++ books I thought we could make a better community wiki version. Providing QUALITY books and an approximate skill level. Maybe we can add a short blurb/description about each book that you have personally read / benefited from. Feel free to debate…

Hi..
I have a function where i use bitset.Now i need to convert it to a dynamic bitset..
but i don't know how.
Can somebody help me ?

Hey, I'm trying to figure out how to instantiate a 4 bit bitset based on a hex character. For instance, If I have a character with value 'F', I want to create a bitset of size 4 initialized to 1111 or if it is A, i want to initialize it to 1010. I could use a bunch of if statements like so:
fn(char…

If I have an integer that I'd like to perform bit manipulation on, how can I load it into a java.util.BitSet? How can I convert it back to an int or long? I'm not so concerned about the size of the BitSet -- it will always be 32 or 64 bits long. I'd just like to use the set(), clear(), nextSetBit()…

I have a byte array generated by a random number generator. I want to put this into the STL bitset.
Unfortunately, it looks like Bitset only supports the following constructors:
A string of 1's and 0's like "10101011"
An unsigned long. (my byte array will be longer)
The only solution I can think…

Am I missing something painfully obvious? Or does just nobody in the world actually use java.util.BitSet?
The following test fails:
@Test
public void testBitSet() throws Exception {
BitSet b = new BitSet();
b.set(0, true);
b.set(1, false);
assertEquals(2, b.length());
}
It's really…
