Introduction
For this assignment you will write an encoder and a decoder for a modified "book cipher." A book cipher uses a document or book as the cipher key, and the cipher itself uses numbers that reference the words within the text. For example, one of the Beale ciphers used an edition of The Declaration of Independence as the cipher key. The cipher you will write will use a pair of numbers corresponding to each letter in the text. The first number denotes the position of a word in the key text (starting at 0), and the second number denotes the position of the letter in the word (also starting at 0). For instance, given the following key text (the numbers correspond to the index of the first word in the line):
[0] 'Twas brillig, and the slithy toves Did gyre and gimble in the wabe;
[13] All mimsy were the borogoves, And the mome raths outgrabe.
[23] "Beware the Jabberwock, my son! The jaws that bite, the claws that catch!
[36] Beware the Jubjub bird, and shun The frumious Bandersnatch!"
[45] He took his vorpal sword in hand: Long time the manxome foe he sought—
The word "computer" can be encoded with the following pairs of numbers:
35,0 catch
5,1 toves
42,3 frumious
48,3 vorpal
22,1 outgrabe
34,3 that
23,5 Beware
7,2 gyre

Write a program that finds the number of items above the average of all items. The problem is to read 100 numbers, get the average of these numbers, and find the number of the items greater than the average. To be flexible for handling any number of input, we will let the user enter the number of input, rather than fixing it to 100.

Problem:


Cookie Calories


A bag of cookies holds 40 cookies. The calorie information on the bag claims that there are 10 "servings" in the bag and that a serving equals 300 calories. Write a program that asks the user to input how many cookies he or she ate and the reports how many total calories were consumed.


*You MUST use constants to represent the number of cookies in the bag, number of servings, and number of calories per serving. Remember to put constants in all caps!


Make sure to declare and initialize all variables before using them!


Then you can do the math using those constants to find the number of calories in each cookie.


Make this program your own by personalizing the introduction and output.

Your program is going to compare the distinct salaries of two individuals for the last 5 years. If the salary for the two individual for a particular year is exactly the same, you should print an error and make the user enter both the salaries again for that year. (The condition is that there salaries should not be the exact same).Your program should accept from the user the salaries for each individual one year at a time. When the user is finished entering the salaries, the program should print which individual made the highest total salary over the 5 year period. This is the individual whose salary is the highest.You have to use arrays and loops in this assignment.In the sample output examples, what the user entered is shownin italics.Welcome to the winning card program.
Enter the salary individual 1 got in year 1>10000
Enter the salary individual 2 got in year 1 >50000
Enter the salary individual 1 got in year 2 >30000
Enter the salary individual 2 got in year 2 >50000
Enter the salary individual 1 got in year 3>35000
Enter the salary individual 2 got in year 3 >105000

This assignment requires you to write a program to analyze a web page HTML file. Your program will read one character at a time from the file specifying the web page, count various attributes in the code for the page, and print a report to the console window giving information about the coding of the page.
Note that a search engine like Google uses at least one technique along similar lines. To calculate how popular (frequently visited or cited) a web page is, one technique is to look at as many other worldwide web pages as possible which are relevant, and count how many links the world's web pages contain back to the target page.
Learning Objectives
To utilize looping structures for the first time in a C++ program
To develop more sophisticated control structures using a combination of selection and looping
To read data from an input file
To gain more experience using manipulators to format output in C++
To consider examples of very simple hypertext markup language (HTML)
Use UNIX commands to obtain the text data files and be able to read from them
Problem Statement
Your program will analyze a few things about the way in which a web page is encoded. The program will ask the user for the name of a file containing a web page description. This input file must be stored in the correct folder with your program files, as discussed in class, and it must be encoded using hypertext markup language, or HTML. The analysis requires that you find the values of the following items for the page:
number of lines (every line ends with the EOLN marker; there will be an EOLN in front of the EOF)
number of tags (includes links and comments)
number of links
number of comments in the file
number of characters in the file (note that blanks and EOLNs do count)
number of characters inside tags
percentage of characters which occur inside tags, out of the total
Here is an example of a very simple HTML file:

Course Web Page
This course is about programming in C++.
Click here You may assume that the HTML files you must analyze use a very limited subset of basic HTML, which includes only the following "special" items: tag always starts with '<' and ends with > link always starts with " comment always starts with "" You may assume that a less-than symbol (<) ALWAYS indicates the start of a tag. A tag in HTML denotes an item that is not displayed on the web page, and often gives instructions to the web browser. For example, indicates that the next item is the overall title of the document, and indicates the end of that section. In tags, both upper and lowercase letters can be used. Note on links and comments: to identify a link, you may just look for an 'a' or 'A' which occurs just after a '<'. To identify a comment, you may just look for a '!' which follows just after a '' (that is, you do not have to check for the two hyphens). You may assume that these are the only HTML language elements you need to recognize, and that the HTML files you process contain absolutely no HTML syntax errors. Note: it is both good style because readability is increased, and convenient, to declare named constants for characters that are meaningful, for example const char TAG OPEN = ' Sample Input Files Program input is to be read from a text file. Your program must ask the user for interactive input of the file name. You can declare a variable to store the file name and read the user's response Miscellaneous Tips and Information You should not read the file more than once to perform the analysis. Reading the file more than once is very inefficient. The simplest, most reliable and consistent way to check for an end of file condition on a loop is by checking for the fail state, as shown in lectures. The eof function is not as reliable or consistent and is simply deemed "flaky" by many programmers as it can behave inconsistently for different input files and on different platforms. You may use only while loops on this project if you wish; you are not required to choose amongst while, do while and/or for loops until project 4 and all projects thereafter. Do not create any functions other than main() for this program. Do not use data structures such as arrays. You may only have ONE return statement and NO exit statements in your code. You may only use break statements inside a switch statement in the manner demonstrated in class; do not use break or continue statements inside loops. #include // used for interactive console I/O #include // used to format output #include // used to retrieve data from file #include // used to convert data to uppercase to simplify comparisons #include 11 for string class functions int main() { 1 //constants for analysing HTML attributes const char EOLN = '\n'; const char COMMENT_MARK = '!'; const char LINK='A'; //constants to format the output const int PAGEWIDTH = 70; const char UNDERLINE = '='; const char SPACE = const int PCT_WIDTH = 5; const int PCT_PRECISION = 2;

In this exercise you will debug the code which has been provided in the starter file. The code is intended to take two strings, s1 and s2 followed by a whole number, n, as inputs from the user, then print a string made up of the first n letters of s1 and the last n letters of s2. Your job is to fix the errors in the code so it performs as expected (see the sample run for an example).
Sample run
Enter first string
sausage
Enter second string
races
Enter number of letters from each word
3
sauces
Note: you are not expected to make your code work when n is bigger than the length of either string.
