Programming Probelm - Please Help!

Can someone tell me what is wrong with my program? (below)
It builds without any errors, but any numbers that I input for cost and markup,
the retail just comes out as "00411168" no matter what numbers I input.
Help would be greatly appreciated!!!

Code:

#include <iostream>  
#include <iomanip>
using namespace std;

double retail (double, double);

int main()
{
   double cost;
   double markup; 

   cout << "What is the item's wholesale cost? ";
   cin >> cost;
   cout << endl;

   cout << "What is the markup percentage? ";
   cin >> markup;
   cout << endl; 

   retail (cost, markup); 


   cout << "The retail price of the item is " << retail << fixed << setprecision(2) << endl;

	return (0);

}

	double retail (double wholesaleCost, double markupPercentage)
   {
	  
	   return (wholesaleCost + (wholesaleCost * (markupPercentage/100)));

   }

You call the retail function, yes, but you should be calling it at the place where you want to print its return value.

I should call it in the cout statement?

Yes, instead of just using the function name like you did (which results in a function pointer, but you can ignore this for now).

so like this?

cout << cost << markup << "The retail price of the item is " << retail << endl;

No, like this:

Code:

cout << "The retail price of the item is " << retail(cost, markup) << fixed << setprecision(2) << endl;

It worked! Thank you!!!
