Question

So I'm not sure what I'm trying to do here. I don't understand how *adr works, I guess it's a

pointer to the struct Address. How do I complete this function? And how would I have it

just return the zip code or one element if I wanted to?

I have two structs:

struct Address
{
   int number; // street number
   string street; // street Name
   string city; // city
   short zip; // zip code
   string state; // state
};

struct Client
{
   int id; // ID
   string name; // Name
   Address *adr; // ZIP code
   double balance; // Account balance
   string lastTrans; // Date of last transaction
};

And two functions:

Address * newAdr()
{
    Address * na = nullptr;

   na = new Address;

   cout << "\n Enter new address: " << endl;

   cout << " Street Number: ";
   cin >> na->number;

   cout << "\n Street Name: ";
   cin >> na->street;

   cout << "\n City: ";
   cin >> na->city;

   cout << "\n Zip: ";
   cin >> na->zip;

   cout << "\n State: ";
   cin >> na->state;

cout << endl;

   return na;
}

The newAdr() function is fine. But now I call it within this next function:

Client * newClnt()
{
   Client * nc = nullptr;

   nc = new Client;

   // call first newAdr, then complete the rest

   nc->adr = newAdr();

   cout << "\n Please enter other client info: " << endl;

   cout << " Client ID: ";
   cin >> nc->id;

   cout << " Client Name: ";
   cin >> nc->name;

   cout << " Client Balance: ";
   cin >> nc->balance;

   cout << " Client Last Transaction: ";
   cin >> nc->lastTrans;

   // complete the rest

   cout << endl;

   return nc;
}

Hi,

Please find the answer below::

Call the function newClnt and save it's result to pointer of client. Now this pointer will contains all the information about the client personal details and address as well.

Please find the code below where print function is defined and using pointer to client as parameter and printing all the details.

If wants to add a function to return particular info that can use -> to get the value.

main.cpp

#include <iostream>
using namespace std;

struct Address
{
   int number; // street number
   string street; // street Name
   string city; // city
   short zip; // zip code
   string state; // state
};

struct Client
{
   int id; // ID
   string name; // Name
   Address *adr; // ZIP code
   double balance; // Account balance
   string lastTrans; // Date of last transaction
};

Address * newAdr()
{
   Address * na = nullptr;

   na = new Address;

   cout << "\n Enter new address: " << endl;

   cout << " Street Number: ";
   cin >> na->number;

   cout << "\n Street Name: ";
   cin >> na->street;

   cout << "\n City: ";
   cin >> na->city;

   cout << "\n Zip: ";
   cin >> na->zip;

   cout << "\n State: ";
   cin >> na->state;

   cout << endl;

   return na;
}

Client * newClnt()
{
   Client * nc = nullptr;

   nc = new Client;

   // call first newAdr, then complete the rest

   nc->adr = newAdr();

   cout << "\n Please enter other client info: " << endl;

   cout << " Client ID: ";
   cin >> nc->id;

   cout << " Client Name: ";
   cin >> nc->name;

   cout << " Client Balance: ";
   cin >> nc->balance;

   cout << " Client Last Transaction: ";
   cin >> nc->lastTrans;

   // complete the rest

   cout << endl;

   return nc;
}

void printDetails(Client * nc){
   cout << "\nClient ID: ";
   cout << nc->id;

   cout << "\nClient Name: ";
   cout << nc->name;

   cout << "\nClient Balance: ";
   cout << nc->balance;

   cout << "\nClient Last Transaction: ";
   cout << nc->lastTrans;

   Address * na;
   cout<<"\nAddress info"<<endl;
   na = nc->adr;

   cout << "\nStreet Number: ";
   cout << na->number;

   cout << "\n Street Name: ";
   cout << na->street;

   cout << "\n City: ";
   cout << na->city;

   cout << "\n Zip: ";
   cout << na->zip;

   cout << "\n State: ";
   cout << na->state;

}

int main() {

   Client *myClient;
   myClient = newClnt();

   printDetails(myClient);

   return 0;
}

output:
