Class Declaration into main??

[seungyeon]

Write your question here.
My class wasn't declared?

#include "lab4.h"
#include <iostream>

using namespace std;

int main()
{
	char repeat;
	do
	{
	labf box;
	
	double rad,heightz,sidez;
	int choose;
	cout << "Select a shape: " << endl << "1. sphere " << endl << "2. cube " << endl << "3. cylinder";
	cin >> choose;
	
	switch(choose)
	{
		case 1 : cout << "Enter the radius of a sphere: ";
				 cin >> labf.setradius(rad);
		box.calcvols(); break;
	
		case 2 : cout << "Enter the side of a cube: ";
 		   		 cin >> labf.setside(sidez);
		box.calcvolc(); break;
	
		case 3 : cout << "Enter the height of a cylinder: ";
				 cin >> labf.setheight(heightz);
				 cout << "Enter the radius of a cylinder: ";
				 cin >> labf.setradius(rad);
		box.calcvolr(); break ;
	
	}
	
	
	
	cout << "Do you wish to continue? y or w and ENTER to continue: ";
	cout << endl;	
	}while (repeat == 'y' || repeat =='w');
}

	cout << "The volume of the sphere is " << volumes << endl;
}

Your method declaration signatures does not match with their implementation. For instance void setradius(); has no parameter.

Add at the top of the header the directive #pragma_once if it is still complaining show us the error message because I don't have an IDE opened I might have missed something
