Explanation / Answer
int PhoneBook::getNumberByName(const string _name) const{
for (int i = 0; i < num_contacts; i++){
if (contactList[i].getName() == _name)
return i;
}
return -1;
}
string PhoneBook::getNameByNumber(const int _number) const {
for (int i = 0; i < num_contacts; i++){
if (contactList[i].getPhoneNumber() == _number)
return contactList[i].getName();
}
return NULL;
}
void PhoneBook::verifyAllContacts(){
int count = 0;
for (int i = 0; i < num_contacts; i++){ //Assuming we have valid(string s) for phone numbera
if (valid(contactList[i].getPhoneNumber())
count++;
}
contactList1 = new Contact[count];
int m = 0;
for (int i = 0; i < num_contacts; i++){
if (valid(contactList[i].getPhoneNumber())
contactList1[m].setName(contactList[i].getName());
contactList1[m].setPhoneNumber(contactList[i].getPhoneNumber());
if (valid((contactList[i].getEmergencyContact()){
contactList1[m].setEmergencyContact(contactList[i].getEmergencyContact());
else
contactList1[m].setEmergencyContact("")
m = m + 1;
}
delete [] contactList;
contactList = contactList1
num_contact = count;
}
