Thread: functions

i am having trouble with the divide function in the main. any help would be great.

Code:

#include <iostream>
#include "fun.h"
using namespace std;
double divide (double num1, double num2);
int main()

{
	double a, b, c;									//declares variables
	cout<<"Enter two numbers:";							//displays output	
	cin>>a>>b;									//gets input
	cout<<endl;									//ends line

	/**************************************
	*  Adds the value of a and b          *
	*  @param a  a double                 *
	*  @param b  a double 	              *
	*  @return   the sum of the two inputs*
	**************************************/
	c=add(a,b);
	cout<<"The sum of the two numbers is: " <<c;
	cout<<endl;

	
	/***************************************
	*  Subtracts the value of a and b      *
	*  @param a  a double                  *
	*  @param b  a double 	               *
	*  @return   the diff of the two inputs*
	***************************************/
	c=subtract(a,b);
	cout<<"The difference of the two numbers is: " <<c;
	cout<<endl;
	
	
	/******************************************
	*  Mutiplies the value of a and b         *
	*  @param a  a double                     *
	*  @param b  a double 	                  *
	*  @return   the product of the two inputs*
	******************************************/
	c=multiply(a,b);
	cout<<"The product of the two numbers is: " <<c;
	cout<<endl;

	

	/***************************************
	*  Cubes the value of a and b          *
	*  @param a  a double                  *
	*  @param b  a double 	               *
	*  @return   the cube of one input     *
	***************************************/
	c=cube(a);
	cout<<"The cube of the first number is: " <<c;
	cout<<endl;

	
	/***************************************

	*  @param a  a double                  *

	***************************************/
	c=cube(b);
	cout<<"The cube of the second number is: " <<c;
	cout<<endl;


	


	double divide (double num1, double num2)
	{
		double total;  
		total = num1 / num2;
		return total;
	}
		



return 0;
