Set bufferedOutput=True since that is the usual command line behaviour. Updated README.

# Minimal C kernel for Jupyter
# C kernel for Jupyter
This project was forked from [https://github.com/brendan-rius/jupyter-c-kernel](brendan-rius/jupyter-c-kernel) as that project seems to have been abandoned. (PR is pending)
This project includes fixes to many issues reported in [https://github.com/brendan-rius/jupyter-c-kernel](brendan-rius/jupyter-c-kernel), as well as the following additional features:
* Option for buffered output to mimic command line behaviour (useful for teaching, default is on)
* Command line input via `scanf` and `getchar`
* Support for `C89`/`ANSI C` (all newer versions were already supported and still are)
Following limitations compared to command line execution exist:
* Input is always buffered due to limitations of the jupyter interface
* When using `-ansi` or `-std=C89`, glibc still has to support at least `C99` for the interfacing with jupyter (this should not be an issue on an OS made after 2000)
## Use with Docker (recommended)
* `docker pull xaverklemenschits/jupyter-c-kernel`
* `docker run -p 8888:8888 xaverklemenschits/jupyter-c-kernel`
* Copy the given URL containing the token, and browse to it. For instance:
* `docker pull xaverklemenschits/jupyter-c-kernel`
* `docker run -p 8888:8888 xaverklemenschits/jupyter-c-kernel`
* Copy the given URL containing the token, and browse to it. For instance:
```
```bash
Copy/paste this URL into your browser when you connect for the first time,
to login with a token:
http://localhost:8888/?token=66750c80bd0788f6ba15760aadz53beb9a9fb4cf8ac15ce8
