I've been trying to figure out how to implement a way to save this board state throughout a user's inputted path. At the end, I need the output to print out the board states (user's path) of how he or she got the puzzle solved. This puzzle is the 15 Puzzle; but we have it to change by the user's input on what size they want to play (3x3 to 5x5). I need help figuring out how to save the board state of each user input, then print those out in order from beginning to solved puzzle state. Subsequently, I would also need some help on transferring the board state to change with using a vector to store the size based on user input. Yes, this is college work; and I have turned this in last week late. I need help on figuring out how to fix last week's problems to proceed with this week's homework assignment, which is using a first search to solve the puzzle from the current board's state.
calculations.h
main.cpp
I would appreciate any quick responses. I've spent a long time trying to figure this out myself; but as the title states, I'm stumped.

This program is designed to have the user able to play the 15-Puzzle game. Although,
the user is also able to make a choice from 3x3(9) and 5x5(25) puzzle as well. Once
the puzzle is solved, the user has their amount of moves and time displayed.*/
