• The focus of this lab is on using strings. You
  will have an opportunity to work with both C
  style strings and the string data type. This lab
  also gives you an opportunity to use what you
  have learned previously, including using
  functions, array processing, repetition, and
  selection. You will also have an opportunity to
  work with file input and output.
• You are to design and implement a program which
  does encryption and decryption of data from
  files. Encryption is the process of taking plain
  lines of text and performing some algorithmic
  transformation on the data to create an encrypted
  line of text which looks nothing like the
  original. Decryption is the process of taking an
  encrypted line of text and performing some
  algorithmic transformation on the data to recover
  the original line of plain text.
• Encryption and Decryption Approach
• Our approach to encryption and decryption
  involves two strings. The first is an encryption
  / decryption string which we will allow to be up
  to 128 lower case alphabetical characters in
  length. The second string is a line of text from
  a file that is to be encrypted or decrypted.
• Our basic strategy for encrypting data is based
  on mapping alphabetical characters to specific
  values, then doing some simple mathematical
  operations to create a new value. First of all,
  every character in either the encryption string
  or the input string is mapped to a number between
  0 and 25 based on its position in the alphabet.

• Week 6 iLab
• You are to design a program that will allow some
  number of grades (up to a max of 100) to be input
  by the user. After the data has been collected,
  your program should calculate and output the mean
  and median of the collected data, as well as the
  sorted grade information.
• Design Constraints
• Use an integer constant of 100 to specify the
  number of elements in the array you will use to
  collect the grade information. Do not use any
  global variables in your program. Declare any
  arrays you need in your main function and pass
  the arrays as needed into the functions described
  below. The main function is the only function
  permitted to do any output to the console!!! Do
  not do cout operations inside of any other
  function. Your data collection loop in your main
  function must allow the user to enter less than
  100 grades. It must also make sure that the user
  does not try to enter more than 100 grades. Each
  data value entered should be checked to make sure
  it is between 0 and 100. Any other value entered
  should be considered invalid and ignored (ie. not
  counted as a valid input and not stored in an
  array). Once the data is collected, the array and
  the number of grades collected must be passed to
  a function called mean. The mean function must
  loop through the values in the array, summing
  them together. The result of the function is the
  sum divided by the number of grades collected.
  The result must be returned from the mean
  function to the main function, where is it output
  in an appropriate manner (two digits after the
  decimal point). The main function should then
  pass the array and the number of grades collected
  to the median function. The median of a set of
  numbers is the number in the set where half the
  numbers are above it and half the numbers are
  below it. In order to find the median, this
  function will need to sort the original .

• Part 1 of this weeks lab will give you an
  opportunity to use the debugging capabilities of
  Visual Studio. Part 2 will present a problem for
  which you will need to create a test plan and
  actually test an executable program to determine
  if it behaves correctly.
• Part 1 Using the Debugger
• To begin this exercise, create a VC project and
  copy the following code into your project. Make
  sure that the project compiles successfully.

• Complete the following two programs
• Programming Problem 1
• Write a program that generates all the factors of
  a number entered by the user. For instance, the
  number 12 has the factors 2 2 3. This program
  has the following requirements
• A. The user must enter a positive integer. If the
  user enters something else, your program should
  output an error message and let the user enter a
  new value. Use a do/while loop to make sure the
  user input is successful.
• B. The factors must be output in increasing
  order. The lowest factor your program should
  report is 2.
• C. Your program should output 4 factors per line,
  each factor in a field of 10 characters. (Hint
  the number of factors output determines when to
  output endl!)
• D. You will need a while loop to report the
  factors. Here are some helpful hints
• 1. If (a b 0) then a is a factor of b.
• 2. When you have found a factor, output the
  factor and then reduce the number you are working
  with by dividing the number by the factor ie) /
  a
• 1. Design an algorithm in pseudocode to solve the
  problem. Make sure to include steps to get each
  input and to report the output. Include steps to
  deal with error cases as specified above.
• 2. Identify three test cases, one using a number
  with 4 factors, one using a negative number, and
  one using a number with more than 4 factors. For
  each of the three test cases show what inputs you
  will use and what your expected outputs should
  be.
• 3. Write the program to implement your algorithm.
  Test your program using your test cases.
• Programming Problem 2
• This program is designed to analyze the growth of
  two cities. Each city has a starting population
  and annual growth rate. The smaller city has the
  larger growth rate (required). Show the
  comparative populations of each city year by year
  until the smaller city has grown larger than the
  bigger city.

• Week 5 iLab
• Objectives
• Apply structured and modular design principles to
  write programs that meet written specifications
  and requirements. Develop a pseudo-code design
  using appropriate program structure (sequence,
  selection, repetition and nesting) to solve a
  given programming problem. Use appropriate
  selection and repetition statements to implement
  the design. Create user-defined functions to
  implement a modular design. Use appropriate
  parameter passing mechanisms for passing data
  into and getting data back from functions. Use
  ostream and iomanip formatting manipulators to
  display tabulated data. Design and implement a
  menu-driven interface.
• Problem Description
• This program is to give the user the option of
  converting a set of temperatures either from
  Celsius to Fahrenheit (C to F) or vice versa,
  from Fahrenheit to Celsius (F to C), or to quit
  the program. If the user selects either C to F or
  F to C, the program will prompt the user to enter
  three integer values, a starting temperature, an
  ending temperature, and an increment. After these
  values have been entered the program will display
  a table of equivalent C and F (or F and C)
  temperatures, from the starting temperature to
  the ending temperature and incrementing by the
  increment value each row.
• The table must meet all of the following
  criteria
• The table's column headings should display the
  degree symbol, e.g., C and F. The first column
  must be the "from" temperature (C for C to F or F
  for F to C) and the second column the "to"
  temperature (F for C to F or C for F to C). The
  calculated "to" temperatures are to be displayed
  to the nearest tenth of a degree (display exactly
  one decimal place, even if there is no fractional
  part, i
