How do I create my own URL protocol? (e.g. so://…) [closed]
...use to do it reliably you can't do it in managed code and have to do it in C++ (I suppose you could use VB6). You should consider whether you really need to do this and if you do, design it carefully and code it securely. An attacker can easily control the content that gets passed to you by simply i...
How to determine if a string is a number with C++?

}
Or if you want to do it the C++11 way:
bool is_number(const std::string& s)
{
return !s.empty() && std::find_if(s.begin(),
s.end(), [](unsigned char c) { return !std::isdigit(c); }) == s.end();
}

How to count the number of set bits in a 32-bit integer?
...ed to adjust it to work for a particular language (e.g. using uint32_t for C++ and >>> in Java):
int numberOfSetBits(uint32_t i)
