When I run check50 on my code, I apparently initialised the board wrong. https://sandbox.cs50.net/checks/e8394a83a4b645199b6b74abbb525f89

  • Have you tried printing your board out? What is your output? – Gabe Sep 2 '16 at 22:26

check50 has a lot of dependencies in order to work. One of them is that the blank tile is stored as 0 in the board[][] array. Your code appears to change that to -1, which takes up an extra character in the log file output.

If you change your code to simply use 0 as the blank, it is likely to work. You might also find it useful to carefully review the code in main().

  • My problem is that I did use 0, but it broke so many things, since the rest of the empty board is also 0s, it causes weird glitches, thus why I used -1. The spec did say you can use any character to represent the empty space. – dehan-jl Sep 5 '16 at 7:54
