So I just made the greyscale function and it passes check50 but when I try to open or download the output.bmp file, it doesn't show anything. Anyone know how to fix this? This was the command I put in to the console ~/pset4/filter/ $ ./filter -g images/stadium.bmp outfile.bmp
Did you actually run the program locally? If you went straight to check50, the code ran on a remote server, so the output file wouldn't have been created locally. You can't open a file that doesn't exist. Also, are you in the same directory where you executed filter and the output file was created?
