This main program will set things up, read the values from the file, and print the output sentences. You will also need the file lab5.h TO GET THE FILES YOU NEED First move to your class folder by typing: cd csc60 The following command will create a directory named lab5 and put all the needed files into it below your csc60 directory Type: cp -R /gaia/home/faculty/bielr/files_csc60/lab5 Spaces needed: (1) After the cp T Don't miss the space & dot (2) After the -R (3) After the directory name at the end & before the dot. After the files are in your account and you are still in csc60, you need to type: chmod 755 lab5 This will give permissions to the directory. Next move into lab5 directory, and type: chmod 644 lab5* This will give permissions to the files Your new lab5 directory should now contain: lab5.c, lab5.h, lab5a.dat, lab5b.dat INPUT/OUTPUT DESCRIPTION: The input is two lists of unknown length of integer values in the file lab5a.dat and lab5b.dat.
