Check to see if it is prime; if not, use the list of primes and modulo arithmetic.

According to the compilers (clang++ and g++) that is a valid function definition. I'm assuming string is a std::string.

My solution is below (this challenge is similar to, Project Euler #17). It relies upon a few boost libraries program_options and lexical_cast;

The logic required to convert a integral type (in...

Couple of quick questions:
(1) Should we also handle separators that correspond to different localizations (i.e. comma separators (en_CA.utf8), period separators (de_DE.utf8 for example), ... is...

The original post made no promise of anything more than threads would call std::sort on different containers (I felt that situations like the following could occur: thread 'a' might call std::sort on...

(1) I'm confused. Based upon the method name, it looks like you are trying to convert a binary representation of a number to an unsigned int. If you want to do this, you have to guarantee that the...

STL sort is not thread safe (unless you lock the container). In case you are wondering why it is not thread safe:
(1) if iterators become invalidated (std::vector<>, std::deque<>, and other...

Do you mean the header file for iostream?
Are you including the iostream header before you make calls to std::cout?
Please remember to include std:: (the header iostream is contained within the...

Within the C standard library there is a function called:


tolower


Its probably best if you investigate these options and come up with a solution for yourself.

Cheers

Bit shifting and masking can be incredible quick (it depends on the platform). For example, a bit shift on some platforms can take less time than an addition. Further, you can remove the |= for +=...

(1) Don't use cout; (it looks too similar to std::cout)
(2) I assume that you have a typos at lines marked with * (and are meaning to use count);
(3) What is the type of exampleString? (assuming...

Honestly: there is probably a better way to design this; but without more details of the problem domain I can't give you any better solutions. It sounds like you are wanting to use the flyweight...

So I investigated further. You'll have to edit (from within the doom root folder):


neo/sys/scons/SConscript.core

and change the following:


if ( local_dedicated == 0 ):...

The problem that you are getting is one most likely the libraries libX11, libXext, and libXxf86vm are not installed. However the other possibility is that the libraries are in a location that is not...

Clang 3.0 is in the 12.04 LTS repositories (along with libclang).

Cheers,

I quickly tried to compile your code with the same command;


clang++ --std=c++0x test.cpp


It worked properly (however, when asking a question like this, it is usually best to give the...

Your makefile appears to be correct (but add an all target -> all : asteroid). To get make to compile the program fully, (it appears that geany_run_script.sh is looking for the executable ship,...

A few points:
(1) careful with double maps (because mmap["a"]["b"] is not equivalent to mmap["b"]["a"]); it might be better to use


std::map<std::pair<std::string, std::string> >, int>
...

Solution using templates in C++
(1) it relies upon the fact that elements are unique in std::set<type>



#include <iostream>
#include <set>

using namespace std;

It looks like the mit keyserver is being swapped with requests. Try using the ubuntu keyserver instead.

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A040830F7FAC5991

Thanks for the information. I'm just curious why it reports BADSIG as the error.

I'm getting the same error. I think google has updated their signing key, but forgot to put the public key online (i.e. we are still using the old public key).

Sorry, I misspoke, I should have said partition or device (instead of disk). But it doesn't just check the filesystem. It checks the underlying physical device (only the CHS of the associated...

Umm ... according to the man pages of badblocks (which is used by fsck.ext3):
