The thing he tried to point out is that your program is doing things that make no sense much earlier than where you think your problems lie, and I tend to agree. If you are reading the file and then discarding what you read, that just doesn't make sense. > I am then trying to pass this parameter to the next function so that > the distance from the start node can be calculated You are calling populateNodeTable twice, which already makes no sense. I'd first try to call this function once and then verify the results by outputting the content of the node table. Once that is done and the content is what you would expect it to be, then you can start trying to implement Dijkstra.
