Thread: "Expressions must have (pointer-to-)" I'm stuck. :(

So I wrote out my code, and yes there is probably a better way I could have done it, but I'm not going for awesome. I just want to get it done. I was almost done and one of my variables came out (pointer-to-). I tried to define in as float, int, and double but nothing worked. Now I'm stuck. Any suggestions? Its on line 28, the second while in my "int main()" section. RoomTiles = RoomTiles + RoomTiles(RoomNumb); Thanks in advance!

Code:

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

//Function prototypes
void GetRoomNumb (float& RoomNumb);  
void GetRoomTiles (double& RoomTiles); 
void GetBoxAmt (float& BoxAmt, float& Extra); 

int main()
{
    //Variable Declarations
    float RoomNumb; 
    double RoomTiles; 
    float BoxAmt; 
    float Remainder; 

    GetRoomNumb(RoomNumb); 
    while (RoomNumb > 0) 
    {
        GetRoomTiles(RoomTiles);  

        std :: cout << "Room requires " << RoomTiles << " tiles." << endl; 

        while (RoomNumb > 0) 
        {
            RoomTiles = RoomTiles + RoomTiles(RoomNumb); 
        }

        RoomNumb--; 
    }

    GetBoxAmt(BoxAmt, Remainder); 
    std :: cout << "Total tiles required is " << RoomTiles << "." << endl
                << "Number of boxes needed is " << BoxAmt << "." << endl 
                << "There will be " << Remainder << " tiles." << endl; 

    return 0; 
}
