Thank you so much! I never would had thought to enable GL_COLOR_MATERIAL.

Here is my code. It is supposed to be a sky background, with a green floor and a sphere in the air. Doesn't really matter what color the sphere is. I think it is blue now. I really appreciate your...

Ok, I tried that, didn't do anything. I put glEnable(GL_NORMALIZE); in my init() function. Everything is still gray.

What do you mean by my normals? It worked fine and was green until until I added my sphere. Now my ground and sphere is just gray.

I'm drawing a sphere and some ground. I used GL_POLYGON to draw a rectangle and colored it green. When I added a sphere, my ground just turned black. Is this because the sphere is a 3d object and...

Thank you! that worked

I'm pretty new to opengl but been using c++ for a while now. How can I display variables using this? I can display single characters by using

glutStrokeCharacter(GLUT_STROKE_MONO_ROMAN,'0');
...

so that part would be right without the &?

I just figured something out. I don't know if it going in the right direction or not but I forgot to put the "&" when I created the new lists. Here is what I put in the drive file to create and copy...

Thanks. I think I see how it all works, just not sure which part is actually wrong. Now it compiles and runs. It shows the two lists that it read in then crashes when it tries to copy them. When I...

Ok, I understand that I need an operator=, copy constructor, and a destructor. After I use my operator= to make a shallow copy of my list, do I then use the destructor on the original list and then...

Thanks for the help! I was able to fix 1 and 4. I changed some of my code. Now it is just not copying the original list to the new list. When I debug it, says it can't evaluate "info" and "next"....

I have been working on this for a few days now. I'm just trying to make a deep copy of a template linked list. I have successfully copied the list, but when I enter a new item to the new list, it...

Thank You! That helped so much. Problem solved

Here is SortedType.h

#include "ItemType.h"
using std::bad_alloc;
// Header file for Sorted List ADT.
template<class ItemType>
struct NodeType;

template<class ItemType>
class SortedType

I have an assignment to use templates for a linked sorted list. The SortedType.h file is in our book and that is what we have to change. I understand how to do all of that and it compiles and...

That's exactly what I was thinking. The directions specifically said to put the input data into an "item", then put the item in the list. Right now I keep getting errors when I use the "cin >> item"...

Hey. I'm trying to simply input items into a list, then be able to sort them and do whatever. I've done this before for my previous classes, but we have we have to use class files out of the book and...

Hey. I have to write a Fraction class for homework and overload for the Fraction class the operators +, -, *, /, +=, -=, *=, /=, and << (the insertion operator). Can somebody please tell me what...

I'm trying to figure out how to do template lists. I have this

GList<int> list1;
GList<float> list2;
GList<string> list3;
ifstream inFile;
inFile.open("data.txt");
while(!inFile.eof()){...
