Thread: swaping numbers

I am trying to put three numbers in order from smallest to largest by swaping them. I can figure out how to get all of them to display after they are swapped. Any help would be great.

Code:

void swap2(double a, double b)
{	
	double temp = a;
	a = b;
	b = temp;
}

int main()
{
	double a, b, c;	
	cout<<"Enter three numbers.";						
	cout<<endl;				
	cin>>a >>b >>c;				
	cout<<endl;			
		
	if (a < b && a < c)					
	{
			
         	cout<<a;	 
	cout<<endl;							
	}

	else if (b < c)
	{
		cout<<b;
		cout<<endl;
	}
	
	else 
	{
		swap2(b,c);
		cout<<c
		cout<<endl;
		cout<<b;
		cout<<endl;
	}

return 0;
}
