Question
Assuming that the usephone2.cpp (listed below) is modified to add the following statement: cout << phonebook.search("Smith"); // displays Smith's phone number Please modify Myphone class so that the above statement compiles and generates the desired output. Please submit all files including that you modified. You must add comments to explain the changes made by you. // usephone2.cpp #include "myphone.h" #include #include using namespace std; #define MAX 50 int main() { MyPhone phonebook(MAX); // a phonebook of size 50 char name[31], num[21]; ifstream infile("phone.txt"); // open a file for reading if (infile.fail()) { cerr << "Failed to open data file "; return 1; } // Read phone records from the file into char arrays. while (! infile.eof()) { infile >> name >> num; // Ask phonebook to save the current phone record. phonebook.addRecord(name, num); } // while infile.close(); // close the data file // Ask phonebook to show phone records ordered by names. cout << " Books by name:"; phonebook.byName(); cout << " "; // Ask phonebook to show phone records ordered by phone numbers. cout << " Books by number:"; phonebook.byPhone(); cout << " "; cout << phonebook.search("Smith"); // displays Smith's phone number // // Tests when a name isn't not found. // cout << phonebook.search("Smih"); return 0; } // myphone.h declares MyPhone class // A class serving as an interface to manipulate PhoneRec objects. #include "phonerec.h" #ifndef MYPHONE #define MYPHONE class MyPhone { PhoneRec *phonelist; // points to the first PhoneRec object. int size; // The size of the PhoneRec array int counter; // current counter void sortName(); void sortPhone(); void showAll(); public: MyPhone(int howmany); // constructor ~MyPhone(); // destructor void addRecord(char *nm, char *ph); // adds a phone record to the phone list (the array) void byName(); // shows records sorted by names void byPhone(); // shows sorted by phone numbers }; // MyPhone #endif // myphone.cpp implements MyPhone class #include "myphone.h" #include MyPhone::MyPhone(int n) // constructor { // n denotes the max. # of records phonelist = new PhoneRec[n]; // allocate space dynamically size = n; counter = 0; } MyPhone::~MyPhone() // destructor { delete phonelist; // release the dynamically reserved space } void MyPhone::sortName() { PhoneRec temp; // Sortthe records in ascending order by names. for (int i=0; i < counter-1; ++i) for (int k=i+1; k 0) { /* swap */ temp = phonelist[i]; phonelist[i] = phonelist[k]; phonelist[k] = temp; } } void MyPhone::sortPhone() { PhoneRec temp; // Sortthe records in ascending order by phone numbers. for (int i=0; i < counter-1; ++i) for (int k=i+1; k < counter; ++k) if (strcmp(phonelist[i].getPhone(), phonelist[k].getPhone()) > 0) { /* swap */ temp = phonelist[i]; phonelist[i] = phonelist[k]; phonelist[k] = temp; } } void MyPhone::showAll() { for (int k=0; k < counter; ++k) phonelist[k].showme(); } void MyPhone::addRecord(char *nm, char *ph) // adds a phone record to the list { phonelist[counter].setName(nm); // save the name for the current record phonelist[counter].setPhone(ph); // save the phone number for the currect record ++counter; // update the counter } void MyPhone::byName() // shows records sorted by names { sortName(); showAll(); } void MyPhone::byPhone() // shows records sorted by numbers { sortPhone(); showAll(); } //Answer suppose to be here Void MyPhone::phonebook.search(char*,++i) { While (found=true && i=<0) if (strcmp(phonelist[i].getPhone(), phonelist[k].getPhone()) > 0) phonelist[i].getName(); else found=false; } //please help // phonerec.h // The declaration file for the PhoneRec class. #ifndef PHONEREC #define PHONEREC class PhoneRec { char name[31]; char phonenum[21]; public: PhoneRec(); // default constructor void setName(char *nm); char * getName(); void setPhone(char *ph); char * getPhone(); void showme(); }; // PhoneRec #endif // phonerec.cpp Implementation file for the PhoneRec class. #include "phonerec.h" #include #include using namespace std; PhoneRec::PhoneRec() { }; // default constructor void PhoneRec::setName(char *nm) { strcpy(name, nm); } char * PhoneRec::getName() { return name; } void PhoneRec::setPhone(char *ph) { strcpy(phonenum, ph); } char * PhoneRec::getPhone() { return phonenum; } void PhoneRec::showme() { cout << name << " " << phonenum << endl; }Explanation / Answer
