First post here but I've been digging around for a solution to this bug.
I am getting an error "string subscript out of range"

PhoneBook is an array of class Contact object pointers.

static const int maxSize = 10;
Contact* phoneBook[maxSize]; //array of contact pointers

where Contact is defined as

class Contact

public:
 Contact();

 std::string firstName;
 std::string lastName;
 std::string name; //lName + fName
 std::string phoneNumber;
 std::string address;
;

Here is my bubble sort function.

void AddressBook::bubbleSort(Contact phoneBook[], int length)

Contact temp; 

for (int i = 0; i < length; i++)//for n-1 passes

 for (int j = 0; j < length - 1; j++)
 
 if (phoneBook->name[j] > phoneBook->name[j + 1])
 
 temp = phoneBook[j];
 phoneBook[j] = phoneBook[j + 1];
 phoneBook[j + 1] = temp;
 

 
 

here is addContact

void AddressBook::addContact(std::string fName, std::string lName, std::string pNumber, std::string addr) 

 if (isFull())
 
 std::cout << "Is full" << std::endl;
 return;
 

 Contact *contact = new Contact;

 contact->firstName = fName;
 contact->lastName = lName;
 contact->name = lName + ", " + fName;
 contact->phoneNumber = pNumber;
 contact->address = addr;

 std::cout << contact->name + " has been added!" << std::endl;
 phoneBook[length] = contact;
 length++; 

 bubbleSort(phoneBook[maxSize], length);

and lastly, where i use it (source.cpp)

switch (choice) 
{
case 1:
 addrBook.addContact("Ty", "Le", "6191231234", "1234 State Street");
 addrBook.addContact("Zak", "Zachary", "6191231234", "1234 Avenue Drive");

I know for a fact that the problem originates from the bubbleSort function because it'll work fine when I comment it out of addContact().

Here's a picture of my error

This is almost a typo. Instead of indexing the name string in

 if (phoneBook->name[j] > phoneBook->name[j + 1])

you want to index phonebook

 if (phoneBook[j].name > phoneBook[j + 1].name)
