9.12 Homework 3 - Flle IO HW3: Mountain Path Simulation Due in Zybooks, Wednesday 19 September 2018 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 l/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 Subscripts 4. 3011 2900 2852 2808 27912818 2972 2937 2886 2860 2830 2748 2937 2959 2913 2864 2791 2742 4 2999 2888 2986 2910 2821 2754 2909 2816 2893 2997 2962 2798 3 Assignment Outline 3.1 Use the starting point for the first column NOTE: You must read in your file name from the user using cin.
