Improve this question In many languages there's a function that breaks strings into parts using specified delimiter. It's often called split . You can find it in Python, C#, Java, JavaScript. But Haskell while being quite mature still lacks such function in the standard

问题 The default install directory of apt-get is /opt. Can I change it to another directory? 回答1: Best way I can think of is to use a symbolic link note that not all programmes are installed to the same directory and /opt may not be the best thing to move. (see end for example of moving only one folder/program) This is what I did with EasyPeasy (Ubuntu 10.04) Follow this code carefully some of the commands can delete important files if used incorrectly. First you need to make sure /opt (or your

问题 I took this example from a different question. I am building an R package with Rcpp. I have a function like fun1 (below) that I want to put into its own .cpp file. Then I want to call fun1 with other functions (like fun() does below). I want fun1 in a separate file because I am going to call it from several Rcpp functions that are in different .cpp files. Are there certain include statements and things I need to do to make the fun1 function accessible in the .cpp where fun() is located? Thank
