Question

In my c++ assignment, I wrote the following code, which works. To get full credit, I have to convert to called functions, which I have difficulty with. The file contains: Turtle Hatchling Oyster Spat Jellyfish Ephyna Sand-Dollar Pluteus Porpoise Calf Trout Fry Manatee Calf Shark Pup Fish Fry The working code is: #include #include #include #include #include #include // Needed to use the sort function http://stackoverflow.com/questions/18292619/c-string-array-sorting using namespace std; // Function Prototypes //*************************************************************************** void welcome(); // Introduces program const int size = 9; int main() { // Introduction not part of repetive loop welcome(); // Welcome Screen system("pause"); // "Press any key to contiue" program pause system("cls"); // Clears screen // variables char again; // To hold y or n ifstream inputFile; string filename, filename2; do { // Insert program between lines //************************************************************************************************************ const int size = 9; // Get filename cout << "Enter filename:" << endl; cin >> filename; system("cls"); // Clears screen // Get file data inputFile.open(filename); if (inputFile) // File varification { cout << "The following are the unsorted names from the file: " << endl; string animalNames[size]; for (int count = 0; count < size; count++) { getline(inputFile, animalNames[count], ' '); // Read names from the file cout << animalNames[count] << endl; // Display names } inputFile.close(); // Close the file // Print to screen cout << endl << " The following are the sorted names: " << endl; // Sort // I was havving difficultyy in adapting the sort algorthym in the textbook, // so I resorted to the Internet: http://stackoverflow.com/questions/18292619/c-string-array-sorting int z = sizeof(animalNames) / sizeof(animalNames[0]); //Get the array size sort(animalNames, animalNames + z); //Use the start and end like this for (int y = 0; y < z; y++) { cout << animalNames[y] << endl; } // Write to file cout << " Enter filename to save data:" << endl; cin >> filename2; ofstream outputFile; outputFile.open(filename2); if (inputFile) // File verificaton { for (int count = 0; count < size; count++) outputFile << animalNames[count] << endl; outputFile.close(); // Close the file } else { cout << "Error opening file." << endl; } } else { cout << "Error opening file." << endl; } //************************************************************************************************************ // Use again cout << endl << "Do you want to start over?
