competitive programming template

TL;DR: write all your code in source/example.cpp, reset the file when done and depend on the judging systems to keep your code :)

To add a new task use: ./create exampleTask

A new file called exampleTask.cpp will be created in the source folder and is added to the cmake build system. The new file contains our current c++ template. All left to do is implement your main!

I recommend a WSL and Clion setup. If you cloned this repo into the windows filesystem, then you probably have windows line endings and get an error when running the create script from WSL. You can change this with dos2unix ./create which changes line endings of the create file. To avoid this in the future read about the git core.autocrlf option.

Try the same as for Linux. When using clang the <bits/stdc++.h> header does not work. I recommend gcc because that's what most juding systems use.

I enabled sanitzers for gcc and clang. Set ASAN_OPTIONS=abort_on_error=1 for easier debugging. Same for UBSAN_OPTIONS. Clion has a settings page for these options. Go to Settings / Preferences | Build, Execution, Deployment | Dynamic Analysis Tools | Sanitizers and put abort_on_error=1 under AddressSanitizer and UndefinedBehaviorSanitizer. This will open the debugger when the sanitizer finds an error.

When debugging reaches end of main the sanitizer might falsely detect an error. Ignore this.

Ok. To create a new executable copy .template.cpp to the source folder and add the line add_executable([name] [name].cpp) to source/CMakeLists.txt.
