I was wondering whether there's a better way of doing this; say we read stdin to a string using fgets() where the string includes a total of n integers (e.g. 5 16 2 34 for n = 4), what would be the best way of extracting them? There has got to be a better way than this hack: for (i=0, j=0; i<n; ++i, j+=pos) sscanf(string+j, "%d%n",...
I basically want to check if part of a string begins with a certain sequence - in this case ftp://, or http://. How would I do this? Thanks ...
I need a short basename function (one-liner ?) for Javascript: basename("/a/folder/file.a.ext") -> "file.a" basename("/a/folder/file.ext") -> "file" basename("/a/folder/file") -> "file" That should strip the path and any extension. Update: For dot at the beginning would be nice to treat as "special" files basename("/a/folder/.file.a...

If I need to get a NUL-terminated char array out of a std::string in a situation where I need to be sure nothing will be allocated, is it safe to use c_str to do so? For example, if I'm inside a destructor and I want to copy some data from a string into a pre-allocated, fixed-size buffer, can I use c_str and be sure it won't throw anythi...
I would like to detect strings that have non-whitespace characters in them. Right now I am trying: !Pattern.matches("\\*\\S\\*", city) But it doesn't seem to be working.

PHP's wordwrap() function doesn't work correctly for multi-byte strings like UTF-8. There are a few examples of mb safe functions in the comments, but with some different test data they all seem to have some problems. The function should take the exact same parameters as wordwrap(). Specifically be sure it works to: cut mid-word if ...
