In your clone of this repository, find the 3-containers exercise. It contains two sub-directories part1 and part2. List
the files in part1:
$ cd archer2-cpp/exercises/3-containers/part1
$ ls
Makefile test.cpp vector_ex.cpp vector_ex.hpp
As before, test.cpp holds some basic unit tests and you can compile with make.
vector_ex.cpp/.hpp hold some functions that work on std::vector - provide the implementations
Copy vector_ex.cpp/.hpp from part 1 into the part 2 folder.
Implement, in a new header/implementation pair of files (map_ex.hpp/.cpp),
a function (AddWord) that adds a string to a std::map as the key, the value
being the length of the string.
You will want to find the documentatation for map on https://en.cppreference.com/
