Go4Expert - question on my definition

im trying to complete my getData definition while avoiding an infinate loop
my error right now is that
error C4716: 'getData' : must return a value
i think i need an if statement? can someone show me an example or something?
Code:
#include<iostream>

#include<iomanip>

#include<string>

usingnamespace std;

struct menuItemType

{

string menuItem;

double menuPrice; 

int numOrdered;

};

menuItemType theMenu[8];

void showMenu();

int getData(int choice); 

double Round(double &totalTax); 

void printCheck(double &tax, double &totalBill); 

int choice=0; // The number the user chooses for the item they want 

int number=0; // Used in the getData function

int x=0; // used in "for" loop to initialize numOrdered to 0.

double bill = 0.0; 

double totalBill = 0.0; // w/ tax

double tax = 0.0; 

double taxRate = .05; // tax%
