Need to upgrade the program below to include FileIO. Get user input for the filename, and then read the names from the file and form the last name string.

HINT: You need to use getLine() for reading the file and perhaps for reading the filename from the keyboard.

int main() { vector names; int count = 0; int choice = Menu(); while (choice != 0) { switch (choice) { case 1: { getName(names, count); } break; case 2: { string name; cout << "Enter name to remove: "; getline(cin, name); int x = removeName(names, count, name); if (x == -1) { cout << "Name is not in the list" << endl; } else { count = x; } } break; case 3: { displayName(names, count); } break; case 4: { string name; cout << "Enter name to find: "; getline(cin, name); int num = findName(names, count, name); if (num == -1) { cout << "Name not found in the list" << endl << endl; } else { cout << "Name found at number " << num << " in the list." << endl << endl; } } break; case 5: { sortName(names, count); } break; case 6: { cout << getLastNames(names, count) << endl; } break; case 0: { return 0; } break; } choice = Menu(); } return 0; }
