C++ getline errors I am getting getline is undefined error messages. I would like the variables to remain as strings. Below is my code.

#include

#include

using namespace std;

int index = 0; // variable to hold how many customers are entered

struct Address //Structure for the address.

{

int street;

int city;

int state;

struct Customer

{

string firstNm, lastNm;

Address busAddr, homeAddr;

};

// Functions

int displayMenu();

Customer getCustomer();

void showCustomer(Customer);
