Thread: Recalling Functions?

First off, I'd just like to point out that I'm quite new to C++. Anyways, I'm trying to make an inline function return to the main function if a switch case is met. The compiler error is as follows:

--------------------Configuration: healthfair - Win32 Debug--------------------
Compiling...
healthfair.cpp
C:\CS151\healthfair\healthfair.cpp(66) : error C2065: 'main' : undeclared identifier
C:\CS151\healthfair\healthfair.cpp(97) : error C2373: 'main' : redefinition; different type modifiers
Error executing cl.exe.

healthfair.exe - 2 error(s), 0 warning(s)

Here is the code (I will bold and enlarge the two error lines for easier reading):

Code:

// Health Fair
// Created by Ty Guenley
// 02-09-05

#include <iostream.h>

// Required header and namespace for colors
#include "Console.h"
namespace con = JadedHoboConsole;

// Body Mass Index Inline Function
inline void bmi()
{
    // Required Variables
    char bmireturn;
    int feet, inches, pounds;
    float meters, kilograms, bmi;

    // Required stream for colors
    using std::cout;
    using std::endl;

    // Clear Screen
    cout << con::clr;

    // Body Mass Title and Intro
    cout << con::fg_gray << "-" << con::fg_white << "="
        << con::fg_cyan << "Body Mass Index" << con::fg_white
        << "=" << con::fg_gray << "-";

    // Get User's Height and Weight
    cout << con::fg_white << "\n\nEnter your " << con::fg_cyan
        << con::bg_blue << "WEIGHT" << con::fg_white << con::bg_black
        << "in pounds: ";
    cin >> pounds;
    cout << con::fg_white << "\n\nEnter your " << con::fg_cyan
        << con::bg_blue << "HEIGHT" << con::fg_white << con::bg_black
        << "... ";
    cout << "\n\tFeet: ";
    cin >> feet;
    cout << "\tInches: ";
    cin >> inches;

    // Make Calculatations
    inches = (feet * 12) + inches;
    meters = inches * (float)0.0254;
    kilograms = pounds / (float)2.2;
    bmi = kilograms / (meters * meters);

    // Display Results
    cout << "\nYou are " << con::fg_cyan << meters << "m"
        << con::fg_white << " tall.";
    cout << "\nYour mass is " << con::fg_cyan << kilograms << "kg"
        << con::fg_white << ".";
    cout << "\nYour Body Mass Index is " << con::fg_cyan << bmi
        << con::fg_white << ".";

    // Return to main()?
bmim:
    cout << "\n\nWould you like to return to the main menu? "
        << con::fg_gray << "y/n\n";
    cin >> bmireturn;
    switch (bmireturn)
    {
    case 'y':
     main();
        break;
    case 'n':
        cout << con::fg_white << "\nGood-bye!";
        break;
    default:
        cout << con::clr;
        cout << con::fg_white << "\nPlease choose y/n!";
        goto bmim;
        break;
    }
}

// Weight Loss Inline Function
inline void weight()
{
    // Weight Loss Variables
    int sedentary, calories;

    using std::cout;
    using std::endl;
    // Clear Screen
    cout << con::clr;

    // Weight Loss Title
    cout << con::fg_gray << "-" << con::fg_white << "="
        << con::fg_cyan << "Weight Loss" << con::fg_white
        << "=" << con::fg_gray << "-\n\n";
}

void main()
{
    // Required variables
    int select;

    using std::cout;
    using std::endl;

    // Main Title and Copyleft
    cout << con::clr;
    cout << con::fg_gray << "-" << con::fg_white << "="
        << con::fg_cyan << "Health Fair 2005" << con::fg_white
        << "=" << con::fg_gray << "-\t(L)2005 Ty Guenley";

    // Menu Selection
    cout << con::fg_white << "\n\n\t::" << con::fg_gray
        << "Menu" << con::fg_white << "::";
    cout << con::fg_cyan << "\n\n1. " << con::fg_white << "Body Mass Index";
    cout << con::fg_cyan << "\n2. " << con::fg_white << "Weight Loss";
    cout << "\n\nPlease make a selection: ";
    cin >> select;

    // Menu Selection Functions
    switch (select)
    {
    case 1:
        bmi();
        break;
    case 2:
        weight();
        break;
    default:
        cout << con::fg_yellow << con::bg_gray << "/" << con::fg_gray
            << con::bg_yellow << "/" << con::fg_yellow << con::bg_gray
            << "/" << con::fg_white << con::bg_red
            << "Error: Please enter a valid choice!" << con::fg_yellow
            << con::bg_gray << "/" << con::fg_gray << con::bg_yellow
            << "/" << con::fg_yellow << con::bg_gray << "/\n"
            << con::fg_white << con::bg_black;
    }
}

is there a better way to do this? or is it even possible to do it period?

the weight() function is not completed as of yet, but i was going to add the same switch to it as well.

also, in case it matters, i'm using Visual C++ 6.0

thanks much!
