Student Programmer help with error in function calls.

[kmartar]

I am writing a program using functions and I am already to compile when I get a lot of these errors. Can anyone tell what it means?

Error 2 error C2601: 'groceriesMenu' : local function definitions are illegal c:\users\kimberly\documents\visual studio 2012\projects\practice 14\practice 14\source.cpp 98 1 Practice 14

At a guess, you have tried to define one function inside another function, which isn't valid in C++.

i decided to post the code i have. So you can see what i am dealing with. We are to write a program using functions. Our model is a store with three departments in those departments are three more options to choose from.
#include <iostream>
#include <string>

using namespace std;

int main()
{
//Function prototype
void displayMenu();
int getChoice();
void groceryMenu();
void clothingMenu();
void produceMenu();




// Constant doubles
const double apples =.59, oranges = .79, bananas = .29;
const double dresses = 15.00, jeans = 9.00, tshirts = 3.50;
const double beef = 1.50, pork = 1.75, chicken = .89;
char again;
int choice;
double lbs, num, cost, price;

do
{ displayMenu(); // Displays main menu.
choice = getChoice();
cout << "Would you like to try again?";
cin >> again;
}while(again == 'y' || again == 'Y');

system("pause");
return 0;

A bit of indentation would help to make that legible, aided by the use of code tags, [code] your code here [/code]

But the answer is as I surmised previously, you've defined the other functions inside of main(). Your code is a bit like this:

int main()
{
    // Function prototype
    void displayMenu();

    // Variables 
    const double apples =.59;
    
    // some code
    return 0;

    
    // function definition
    void displayMenu()
    {
        // etc
    }
} 

Whereas it should look more like this:

// Function prototype
void displayMenu();

int main()
{
    // Variables 
    const double apples =.59;
    
    // some code
    return 0;
}

// function definition
void displayMenu()
{
    // etc
}

I changed it like you suggested but it is still telling me local function definitions are illegal.

Could you post the updated version of your code please.
