Albert Einstein My therapist told me the way to achieve true inner peace is to finish what I start. So far I've finished two bags of M&Ms and a chocolate cake. I feel better already."-Dave Barry From Cursor Statistics File Operations: Check Spelling Open File -> From Beginning Save File As-> From Cursor Clear Editor All Words The functions you are required to write for this assignment are called when the buttons are clicked on the user interface. They are described under the following sections, File Operations, Check Spelling, Search, and Statistics. File Operations You must write two functions with the following headings: void encrypt (char document[], char filename[]) void decrypt (char document[], char filename[]) The user creates a document by typing characters in the editor. When the user is ready to save the document to a file, the file name must be entered in the field to the right of the Save File As button. The Save File As button is then clicked. The encrypt function is called by the user interface. When called, the characters in the document are passed as a C-string parameter, document, to the encrypt function. The name of the file is also passed as a C-string parameter. The encrypt function opens the file. Each character in the document C-string is then encrypted and stored in the file. The following encryption algorithm should be used to encrypt each character before it is stored in the file: (2) (3) Let length = the amount of characters in the document C-string. Let shift = length % 4+1 For each character in the document (3.1) add shift to that character. (3.2) interchange bit 3 with bit 4 in the character. (3.3) Store the character in the file. When the user wants to open a file, the file name must be entered in the field to the right of the Open File button. The Open File button is then clicked. The decrypt function is called by the user interface. When called, a C-string document, is passed as a parameter to the decrypt function. A C- string containing the name of the file is also passed as a parameter. The decrypt function opens the file. Each character from the file is then read, decrypted, and inserted in the document C-string which was passed as a parameter. The decryption algorithm should reverse the steps of the encryption algorithm When the user clicks on the Clear Editor button, the contents of the editor and file name/s are erased. You do not have to write code for this behaviour. Check Spelling You must write three functions with the following headings: int readWordsDictionary(string dictionary[]); int checkSpelling (string dictionary[], int numWords, char document[], int start, char errorword[]); int checkSpellingAll (string dictionary[], int numWords, char document[], string errorWords[]); The first function reads all the words from the dictionary file, dictionary.txt, and stores them in dictionary, an array of string passed as a parameter. It returns the amount of words in the dictionary, All the words in the dictionary are in lowercase. The function is called as soon as the program starts. The checkSpelling function accepts the dictionary as a parameter as well as a C-string containing the characters of the document. It checks the spelling of all the words that come after location start in the document C-string. If an incorrectly spelt word is encountered, it is copied to the C-string error Word and the function terminates by returning the starting location of the word that has been spelt incorrectly. If there are no spelling errors, the function must return-1. The checkSpelling All function is similar to the check Spelling function. However, it searches the entire document C-string for incorrectly spelt words. Whenever an incorrectly spelt word is encountered, it is inserted in the array of errorWords which was passed as a parameter. The function returns the amount of words that were incorrectly spelt in the document. It should be noted that the user may type uppercase and lowercase letters in the editor. So, "The and "the" are correctly spelt even though the dictionary only contains the word "the". Also, the get Word and getWords functions discussed in the lectures are good starting points for writing the checkSpelling and check Spelling All functions. Search The search feature allows the user to search for a particular word in the document. You must write a function with the following heading to perform the search: int searchword (char document[], int start, char keyword(1) The function must search the document C-string to find the keyword C-string, starting from location start. If the keyword substring is found in the document C-string, you must return the starting location where it was found. Otherwise, return-1. Statistics A Statistics struct is used to store statistics about the document in the edito". It is declared as follows: struct Statistics ( int wordCount; // amount of words in the document int longestWord; // length of the longest word in the document int shortestword; // length of the shortest word in the document int numChars; // total number of characters in the document You must write the following function to generate the statistics and store it in a variable of type Statistics: Statistics getStatistics (char document[]); The function accepts the document C-string, analyses it, and stores the resut in a Statistics struct which is returned to the caller.

You must write the functions required for this assignment in Assignment2.cpp. Since the functions are being called from the user interface code in Graphics.cpp, if any of the function headings in Assignment2.cpp are modified, the program will not compile. The file Given Functions.cpp contains several functions that were discussed during the lectures (e.g. isletter, to UpperCase, byte ToChar, etc.).
