New member, first question

[aveguy311]

Hello! Let me start with this..I have absolutely no previous programming experience and have taken an introductory C++ class. I've had no problems with our previous topics, but this "class" thing has really thrown me for a loop. Here is the problem I am having. I need to write a boolean function to determine whether a "balloon" has popped. Here is the driver function:
/*******************************************
* Program 09 Sample Program
* Written by 06-Apr-2009
*******************************************/
#include <iostream>
#include <iomanip>
#include <string>
using namespace std;
#include "Balloon.h"
/*******************************************
* void main()
* Main driver routine
*******************************************/
void main()
{ string option;
float air;
class balloon b;
// Output title
cout << "Welcome to the Balloon Factory\n\n";
cout << fixed << setprecision(2);
// Main Loop
do {
// Get user option
cout << "Enter action (Add,Release,Quit): ";
cin >> option;
if(option=="Add" || option=="Release")
{ cout << "Enter amount of air: ";
cin >> air;
};
// Add air
if(option=="Add")
b.inflate(air);
// Release air
if(option=="Release")
b.deflate(air);
// Check for pop
if(b.pop())
cout << "Balloon Popped!" << endl;
// Display current values
cout << "Volume: " << b.volume() << endl;
cout << "Diameter: " << b.diameter() << endl;
cout << "Pressure: " << b.pressure() << endl;
cout << endl;
// End of loop
} while(option!="Quit" && !b.pop());
// Finished message
cout << "Thank you!\n";
}

And my header file:

class balloon
#define B 3.15;
#define MAX 100;
{public:
balloon(); //Constructs an empty balloon
void inflate(float); //Adds air to balloon
void deflate(float); //Removes air from balloon
bool pop(); //Checks to see if balloon popped
float volume(); //Returns volume of air in balloon
float pressure(); //Calculates pressure of air in balloon
float diameter(); //Calculates new diameter of balloon
private:
float vol; //Stores current air volume
bool popped; //Status of balloon
};

And, finally, my function file:

//Circle calculation file
#include<iostream>
#include<cmath>
using namespace std;
#include "Balloon.h"

/**********************
*Balloon constructor
*No air
**********************/
balloon::balloon()
{ vol = 0.0;
}
/*********************
*Add air function
*********************/
void balloon::inflate(float air)
{vol = air + vol;
}
/*********************
*Remove air function
*********************/
void balloon::deflate(float air)
{vol = vol - air;
}
/********************
*Balloon pop function
********************/
bool balloon::pop()
{if(vol<=MAX)
{popped = false;
return false;}
else
{popped = true;
return true;}
}


What I need to do is return either a true or false when "vol" has exceeded "MAX" and also store that information in a variable called "popped"(see my header file). But, my bool function gives me either an "overloaded function not found in" message if I try to pass in a variable(like (float vol)), or if I leave the "()" empty I get a bunch of "( missing before ; messages. Grrr!! Can you help me with this one?

If it helps you at all...here is a link to my assignment:

I think that the solution here is incredible simple...but I've spent way too much time staring at the screen with no solution. Thanks for the help!!

The problem is in these two lines:

#define B 3.15;
#define MAX 100; 

Don't put a semicolon in a #define. They are just an automated copypaste, and they will copy in a ; where you don't want them.
main should always return int, never, ever void.
int main()//4 eva!!
