I'd like to create a random string, consisting of alpha-numeric characters. I want to be able to be specify the length of the string. ...

...mes themselves as strings, see this post. Otherwise, a std::map<MyEnum, char const*> will work nicely. (No point in copying your string literals to std::strings in the map) For extra syntactic sugar, here's how to write a map_init class. The goal is to allow std::map<MyEnum, const char*&g...

...ntil I've done ++ often enough to cause an overflow on it's own. Even with char as the type used and CHAR_BITS something low like 5, that's 32 times before this doesn't work any more (that's still argument enough for it being a bad practice, I'm not defending the practice, just explaining why it wor...

...yStr.Split(null); //Or myStr.Split() or: string[] ssize = myStr.Split(new char[0]); then white-space is assumed to be the splitting character. From the string.Split(char[]) method's documentation page. If the separator parameter is null or contains no characters, white-space characters are assume...

Is there an easy way to read a single char from the console as the user is typing it in Java? Is it possible? I've tried with these methods but they all wait for the user to press enter key: ...
