2.) What is the largest positive number in decimal, that can be represented using 8 bits? Each groups of binary numbers can be represented more compactly in base-16 numbering, which is called hexadecimal. The hexadecimal digits are 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F. 3.) What range of positive decimal numbers can one hexadecimal digit represent? Colors on a computer monitor are represented by 6 hexadecimal numbers, the first pair to the left specifies the amount of red to display, the middle pair of numbers specify...

Caesar's cypher is the simplest encryption algorithm. It adds a fixed value to the ASCII (unicode) value of each character of a text. In other words, it shifts the characters. Decrypting a text is simply shifting it back by the same amount, that is, it substract the same value from the characters. Write a Matlab function called caesar that accepts two arguments: the first is the character vector to be encrypted, while the second is the shift amount. The function...

Write a program that reads a series of words (one word per line) from a file named data.txt. Each word in the file should have each of its characters shifted by 1 character value in the ASCII table (incremented) and then that new word with its characters shifted should be printed to a new file named result.txt. Each word from data.txt should be reprinted with its new encoding in result.txt. Your program should not have any knowledge of how many...

Write a program that implements an elementary bit stream cipher. An elementary level bit stream cipher is an encryption algorithm that encrypts 1 byte of plain text at a time. This one uses a given 4-bit bit pattern as the key. The size of the encrypted message that we want to be able to send has a maximum length of 200 characters. You must: 1. prompt the user to input the clear text to be encrypted. You must use printf()...
C++ program to convert between decimal, hexadecimal, and octal. Please Help!!
Hi, I need help writing a program that reads in data (hex, octal or decimal values) from an input file and outputs the values in to another base form (hex, octal,decimal) one line at a time depending on the formatting characters provided by the input file. I am posting the code requirements below and an example of what theinput file will look like and what should be output by the program. I only need the one .cpp program file. Thanks...
