$19\mathrm{.}1$ Lab: Triples

Complete the C$++$ class Triple below so that it represents a vector with $3$ elements: $($a$,$b$,$c$)$

Most of these function bodies can be written in only a few lines. Error checking is not required.

The triple.cpp file is the code unit tested on submission. Implement fetch$()$ before submitting because the unit tests use fetch to check your results.

You can submit unlimited times.
