Useage: pprw output_type input_file output_file This program converts a ppm file of type 3 or 6 into either 3 or 6 (users choice). output_type: The ppm type of the output file. input_file: The name of the input file to covert to another type. output_file: The name of the output file Grader - I forgot to include my readme file, hopefully this still counts even though it's a little late. I also updated my ppm files because I forgot to commit those to git. (I use drop box to keep things updated...)
