Write a C program to visually display the powers of 2. The program is to ask the user to enter a positive integer (which represents the desired power of 2). The program then outputs on succes sive rows the required number of s starting with one single in the first row (representing 20 1), two s in the second row (representing 2 2), four s

write a function that adds two binary numbers that are entered by the user. You may represent each binary number as a string of 0's and 1's. Remember that the calculations need to start at the end of the strings. for binary numbers of different lengths, you may pad the shorter number with 0's in front. Also, make sure that the carry bit is

Build a Visual Basic application that calculates a tip. After the user enters the amount of the restaurant bill, the user may click one of 3 buttons to compute a tip. Once clicked, change the label below the buttons to show the amount to tip. E.g., for a 10.00 purchase, a 15 tip is 1.50. Fors AB A 181 20 For the Exit Button shown in the photo,

The ADFGX cipher with key and matrix ADFG X C H W U IJ Y A T X GOL P V G BSMRE A D F X N QUADRICEPS D K N Q F LL were used to produce the following ciphertext GFAFADFXDXXGDDADGFFGFFGXXGXAFGFGXAGFXXDXAXAADFAAFDAA XDXXFAXXXGDXAXGAGD . Find the message. (Spacing between words is required punctuation is optional but appreciated.) Write the answer to

1. (4pts) Write a countfamily(namelist) function. This function returns a dictionary with keys being the unique last names and values being the number of names with the corresponding last name. For example, Alex Foo and Chris Foo have the same last name. When calling countfamily(Alex Foo, Chris Foo), the return value should be Foo2. When calling

Write a program to allow the user to encrypt and decrypt LFSR-based ciphertext using a user-specied key. Speed is very important for stream cipher design, so you are required to implement the stream cipher using bitwise operations. There are two les for you to decrypt. I need it done in java. (a) LFSR.encrypted was encrypted using the output bits

1. Write the C code that would set an int variable named debugMode to TRUE if the value of d was given anywhere on the command line. Otherwise, the variable should be FALSE. Use the code in lab4a.c as a starting point. Hint use library function strcmp() and assume C Booleans are created. int debugMode 2. Write the C code that would determine if
