// Read before you start: // You are given a partially complete program. Your job is to complete the functions in order for this program to work successfully. // All instructions are given above the required functions, please read them and follow them carefully. // You shoud not modify the function return types or parameters. // You can assume that all inputs are valid. Ex: If prompted for an integer, the user will input an integer.

// Problem 1: initializeStrings (5 points) // Traverse the 2D array of characters variable 'strings' (input from user in main() ) and set all characters in each // array to a null terminator so that there is a 4 row and 35 column 2D array full of null terminators. // The null terminator is represented by the character value '\0' and is used to denote the end of a string. // This may come in use later in the program to know the end of string. void initializeStrings(char strings[NUM_STRINGS][STRING_LENGTH]) {

// Problem 2: printStrings (5 points) // Traverse the 2D character array "strings" and print each of the contained strings. // See the example outputs provided in the word document. Your output should match the example outputs. void printStrings(char strings[NUM_STRINGS][STRING_LENGTH]) {

// Problem 4: encryptStrings (5 points) // Traverse the 2D character array 'strings' and encrypt each string in 2 steps as follows- // 1) Reverse the string. // Hint: Use 'reverseStrings()' for this step. // 2) Then shift those ASCII characters forward by the integer value of 'key'. // If the string is "hello" and key = 2, reversing will get you "olleh" and adding key to it will result in "qnnfj" // If the value of 'key' is large, you will extend past the alphabetical characters and reach non-alphabetical characters. Thats ok.

// NOTE: DO NOT encrypt the null terminator character. Use the null terminator '\0' to find the end string. // *** NOTE: If you were unable to code for reverseStrings(), then skip that step in this function and simply shift the characters ahead by 'key'. // While decrypting in the next function, you will again have to skip the reversing part. You will get partial points in that case. void encryptStrings(char strings[NUM_STRINGS][STRING_LENGTH], int key) { } // Problem 5: decryptStrings (5 points) // HINT: This should be very similiar to the encryption function defined above. // Traverse the 2D character array 'strings' and decrypt each string in 2 steps as follows- // 1) Shift those ASCII characters backward by the integer value of 'key'. // 2) Then reverse the string. // Hint: Use 'reverseStrings()' for this step. // *** NOTE: If you were unable to code for reverseStrings(), then skip that step in this function and simply shift the characters backward by 'key'. // You will get partial points in that case. void decryptStrings(char strings[NUM_STRINGS][STRING_LENGTH], int key) {

// Problem 6: splitAndPrintSentences (10 points) // Split s[] into individual sentences and store them in str[][]. // Read s[] character by character and copy into str[][], such that sentence 1 is in str[0][], sentence 2 is in str[1][] and so on. // Print the char array str[][], so that you will print the separated sentences. Finally return the number of sentences in 'count' // Dont forget to initialize str[][] with nulls. // Hint: Sentences are separated by full-stop.
