Case Study 2：CRM Technologies Build Versus Buy Analysis and Program ManagementYou work for a large Boston based investment firm. They are currently using an older CRM (Client Relationship Management) system. It was home grown/built in house 10 years ago and has served them well but like all old systems, newer technologies have come along that are slicker, more integrated and higher functioning in general. Your boss has come to you and asked you to begin the process of researching solutions. You couldBuild a new one – probably from scratch to use newer technologiesAnalyze commercial purchase-able cloud based solutionsYour task is to create a framework to evaluate all/any short term and longer term costs associated with software ownership. Build versus buy.Creativity and original ideas and concepts are encouraged. Use google, use lecture material and use your intuition.

For this assignment, you are to write a program that takes an image on the standard input and writes a thumbnail of that image on the standard output. Both the input and output files will be in a restricted form of the Portable GrayMap (PGM) format. Such a PGM file contains the following:The string "P5" followed by a newlineThe width and height as ASCII strings separated by a space and followed by a newlineThe maximum value of a pixel which much be less than or equal to 255 followed by a newlineOne byte per pixel with the grayscale value of the pixelThe thumbnail should be scaled such that the image is approximately 200 pixels wide and the height should be scaled by the same proportion necessary to made the width 200. Don't attempt to handle the fractional part of the scaling. Just work in integers. For example in an image that's 1360x200, each 6x6 region of pixels in the original will be represented by 1 pixel in the thumbnail. The final image will then be 226x33. Exactly how you map the 6x6 subset of pixels to the 1 pixel is up to you. Some of the possible strategies include picking the upper left pixel, picking the center pixel, computing the average over the pixels, and potentially others.For processing the input header, I suggest you use the scanf function along the lines of:n = scanf("P5 %d %d %d", &width, &height, &max);Use malloc to allocate space for both the original image and the resulting image. Use either read or getchar to load the memory space for the original image. Use either write or putchar to output the pixels of the thumbnail image. To drive home the details of pointers, don't use any array notation in this program; do all access to the images using pointer arithmetic.For testing, you will probably want to convert your thumbnail into another file format that you can more easily view. The program pnmtopng on tux can be used for that purpose. Also, I've attached two PGM images to this assignment for you to test with.
