This repository implements a custom Xcode C++ template for competitive programming. It makes it easy to define input and expected output if you want to.
This template provides the option to add additional targets to read from an input file or write to an output file. The options are:
This does not include any targets to handle input or output files. It just provides a starting point for your program.
This defines two targets. The normal target is the target without input and output file handling. A second target redirects the standard input to use an input file (input.txt). These two targets make it easy for you to choose between testing with manual input and input from an input file.
This third option defines an additional target, next to the two targets from the input option. This third target redirects the standard output to a file called output.txt. In the end it runs the diff command on the expected_output.txt file and the generated output.txt file and leaves the output of the diff command in a file called diff.txt. To find the diff.txt file, you'll have to go the build directory of the target. You can do this by right-clicking on any of the products (in the Products group) and selecting Show in Finder.
If you want to drag a file into the Xcode project, instead of copying the contents to the input.txt file, you will have to add the file the Copy Files build phase. The file needs to be copied to the build directory in which the compiled program is ran.
This template behaves as the Input type template, but it adds some code that's always used for Google Code Jam. It adds some common includes and the loop for the different cases.
This template behaves as the Input type template, but it adds several input files to easily switch between inputs. Like discussed in Adding you own files, you have to include input files that you drag into the project in the Copy Files build phase. You can also copy the contents to the included input files.
To install the template(s), simply move the encolsing directory to ~/Library/Developer/Xcode/Templates/Project Templates/Competitive/. If it does not exist yet, you'll have to create it. The easiest way to keep the templates up to date is to clone this repository in that directory (so that the contents reside in the Competitive directory).
