CIS 330: Project #3D Worth 3% of your grade Please read this entire prompt! Assignment: 1) Write a new, concrete type of Source called “PNMreaderCPP”. This reader should be identical to your PNMreader class, but it uses C++ file I/O (ifstream) to read the data. 2) Write a new, concrete type of Sink called “PNMwriterCPP”. This writer should be identical to your PNMwriter class, but it uses C++ file I/O (ofstream) to write the data. 3) Modify the main3C.C program to use your new classes in the place of the old ones. Turnin: tar cvf proj3D.tar image.C sink.C source.C PNMreaderCPP.C PNMwriterCPP.C filter.C image.h sink.h source.h PNMreaderCPP.h PNMwriterCPP.h filter.h The program should run identically to the 3C (just using C++’s file I/O mechanisms). Note #1: in previous years, people deleted their previous PNMreaders and PNMwriters … you will need them, so hang onto them. Note #2: 3E, 3F, 3G, 3H, 3I, and 3T will all build on 3C. Therefore, if you are behind, then you can skip this project and still do
