Question

So I have created a nested template (a map of vectors) using stanford’s CS106 C++ library—which I believe is created to follow regular comp-sci modus operandi.

Map<Vector<char> > mv;

I can’t figure out the syntax for adding a key/value pair, where the value is of course a vector entry…
So far I’ve tried variations of this:

mv.put("key", 'A');

Error from the above code: No viable conversion from ‘char’ to ‘Vector’

put() is the member function that adds a key/value pair.

The key is working fine. The problem is inserting the char into the a vector. I have no troubles adding a value to an already created key, it’s just creating a new key with a value that I can’t do.

add() is the member function for adding a char into the vector.

Totally unsure how the syntax is meant to look, I’ve tried searching for a solution with no luck, and my tinkering has been fruitless thus far.

Thanks for any help, much appreciated 🙂

edit: Sorry I should have included this from the start, here is the library documentation: http://www.stanford.edu/class/cs106b/cs106lib/

You can do something like this:

Vector<char> v;
v.add('A');
mv.put("key", v);
