   + https://tildegit.org/left_adjoint/cs161AWinter2024/src/branch/main/arrayofarrays.cpp an examples of how an array of strings would work, this example shows how to find the acrostic of a set of sentences (well, just individual words you can change the code to use getline to make it work with whole sentences)
   + https://tildegit.org/left_adjoint/cs161AWinter2024/src/branch/main/whileArray.cpp this is an example of how to traverse an array only *partially* with a while-loop rather than a for loop
