c++

that compiler is probably installed anyway already.

go/linguaevalia/README.md

- `c`
- `bash`
- `lua`
- `c++`
Adding more is relatively simple: If there is a command that runs code in
a language given a file, just add [the appropriate line](./linguaevalia.go#L40-L47)

go/linguaevalia/bin/run-c++

#!/bin/sh
result=/tmp/`basename $1 .cpp`
c++ $1 -o $result && $result
rm -f $result
