Document Summary
October 7 c input and output _____ We"d like to write code that interacts with the os, with other programs, and gets data from the file system, the disc, etc. Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video. He gave us two files, an encoder and a decoder. You run the encoder based on an image file. He uses the mario pic as a sample. It doesn"t work on every type of image -- we need to use a simple" image structure, like a . bmp. I have hidden the secret within an image of 179178 bytes. Then, look at the image (looks the same) mario_message. bmp . It looks exactly the same as the input image. Input: is a built-in function in unix and can say if two things diff mario_16_bit. bmp mario_message. bmp. // are exactly equal or different they differ. The secret message is: comp 206 is great!
