I am using Nate Robins' GLUT for Win 32. I have been using VS2015 and VS2010 on alternate systems for development. I've created a simulation of Dijkestra's on 5 nodes and the final output is the shortest path from the source node to the destination node printed in red dotted lines.
However, after a few changes the code simply wouldn't print the dotted lines on VS2015.
The same code works flawlessly on VS2010.

The Complete code is available here.
I really don't understand why the code isn't working on VS2015 but works fine with VS2010. Any help is welcome as I use VS2010 on my desktop and hence carrying it everywhere isn't really possible.
