C++ include bonus please

Please make the code easy to understand, I am trying to learn.

Objective In this assignment, students will load a topographic (elevation) data into a 2D array and write functions to compute the path that requires the least overall change in elevation, from a given starting point. Then, they will display this path to the user Main Topics Covered o Functions o File I/O Problem There are many contexts in which you want to know the most efficient way to travel over land. When traveling through mountains (let's say you're walking) perhaps you want to take the route that requires the least total change in elevation with each step you take call it the path of least resistance Given some topographic data, your program must calculate elevation change walk from one side of a map to the other.
