Spring 2024. CISC 3142. Homework 4 Objective: Develop a command-line tool in C++ that enables users to hide text messages within the least significant bits (LSBs) of an image file and subsequently extract these messages. Project Description: Design the program to interact with the user via the command line. It should prompt the user for input and output file names and whether they wish to encode or decode a message: Encode: ./stego hide image.ppm text_to_hide.txt In this case, the program reads image.ppm and hides the content of text_to_hide.txt in it, properly handling the situation when files are not found or when there are not enough pixels in image.ppm to hide the whole text. Decode: ./stego extract image.ppm output_file.txt In this case, the program reads image.ppm and extracts the hidden message to output_file.txt. Use bitwise operations to encode and decode the text message within the image data. Modify only the least significant bits of each color component (red, green, blue) in the image pixels to embed the message, ensuring minimal visual alteration to the image. The program must include error checking to handle scenarios such as invalid file formats, image files that are too small to contain the intended message, and other potential errors that may arise during file reading/writing. Technical Constraints: Utilize the things we have learned so far: functions, structs, pointers, C-style arrays, and dynamic memory allocation in your implementation. The use of advanced features such as classes, STL containers, or third-party libraries is not allowed for this assignment. Deliverables: Source Code: Submit all source code files (.cpp and .h) necessary to compile and run your program. Make sure your code is well-commented and follows good programming practices. Documentation: Provide a README file that includes: Instructions on how to compile and run your program. A brief description of your program's architecture and design choices. Examples of how to use the program, including command-line syntax. Test Files: You can use a PPM file included with this assignment, use your own text file to hide. Provide the resulting PPM image file after encoding a message and a screenshot or text file demonstrating the successful extraction (decoding) of the message.

Text A: Additional homework questions (5 points): A. (From Chapter 7 material) As we discussed when we covered Chapter 4, eye color in Drosophila depends on the synthesis of two pigments, a red pigment and a brown pigment, resulting in the wild-type (WT) dull red eye color. Production of the red pigment results in brown eyes. If both pathways are blocked, the eyes are white. Thus, recessive cinnabar (cn) homozygotes have bright red eyes, while recessive brown (bn) homozygotes have brown eyes, and double mutants homozygous for both cn and bn have white eyes. Flies with WT eyes that were heterozygous for both cn and bn were crossed with white-eyed flies, and the following results were obtained: Eye Phenotype # of flies Bright red 135 WT 78 Brown 145 White 82 Are the cn and bn genes linked? Test using a chi-square test. If they are linked, what is the map distance? What was the arrangement of alleles on the chromosome homologs in the heterozygous parent? Text B: The following cross involving three genes was performed: Aa Bh Ce x aa bb cc, and the phenotypes and number of progeny are shown below. Each pair of alleles exhibits simple dominance and recessiveness. Progeny Phenotype Number of progeny ABC 181 abc 169 aBC 77 Abc 7 ABc 69 abC 81 aBc 173 AbC 177 1000 Which pair of genes is clearly linked to each other, and which gene is clearly unlinked to the other two? What is the map distance between the two linked genes? HINT: Compare two genes at a time, ignoring the other gene. Combine crosses so you only have the four classes for each pair of genes (A&B, B&C, and A&C), and check if they are linked or assort independently (this will be obvious even without a chi-square test).
