If you have Sublime Text installed, you can use these commands (which are based on the subl command line tool that Sublime Text uses). There is a default template.cpp file that can be used as a template. To make a new file named <filename>.cpp out of this template, simply run the following command.

  bash make-cp <filename>

This will create a new file for you, and open it in Sublime Text for you to modify. To run the file, either follow standard C++ building steps, or you can also do

  bash run-cp <filename>

template.cpp uses the files input.txt, error.txt and output.txt for input, error and output redirection, if the flag ONLINE_JUDGE is not set (most online judges set this flag to true). So, after running the above command, you should be able to see the output in the output.txt file.
