HTML documents came out of the desire to share information from one place to the next. But an early determination was that there was a need to interconnect related documents.

Multi-dimensional arrays, often called a matrix, are possible in C++. C/C++ treats them as an array of arrays. Because of how they are defined, each array within the array will be of the same size. This actually makes them easier to work with. To define them, you use two sets of brackets, and can think…
