How do I "compile" my source code into a program? Can I do it through the C++ program or do I need to download more stuff?

None.
I don't even know the first thing to do..

No. Your program shouldn't need to do this. Console programs are meant to be executed from the console, and as such, the output should still be on the screen.

I did that and then what do I do? How do I see a preview of what I just worked on? What do I type to start? I have so many questions...
None.
You didn't do everything we said then. =|
If you're trying Dev-C++ (which is what I highly suggest currently as it gives the cleanest coding experience in Windows), just start a new file and call it "main.cpp".
Copy and paste the code I showed you into the editor, save it and in the toolbars, there should be a "compile" and/or "run" button. Click on that button to run the file.
Due to the fact that windows is weird, insert the code: "cin.get()" right before "return 0", otherwise, the console will automatically close and you won't see anything. To exit the program, just press enter. Note that the program is simply waiting for an input (cin.get()) before it executes "return 0" which closes the program.
For now, just see if you can get that working. And tell us exactly what you did if you can't get it working.

Do you have a .cpp file in the project? Copy and paste the following into it and then hit ctrl-F5.
Try getting it to print different things. When you're bored of that, copy and paste this:
And then from there, start reading: http://www.cplusplus.com/doc/tutorial/program_structure.html
Code
#include <iostream>
using namespace std;
int main()
{
cout << "Hello, world!" << endl;
return 0;
}
using namespace std;
int main()
{
cout << "Hello, world!" << endl;
return 0;
}

cin >> name;
cout << "Hello, " << name << "!" << endl;

That said...if your console program is meant to be double-clicked from windows, adding
Code
system("pause");
before the return 0; is the right way to go. But this only works for windows.That's only if you want the ugly "Press any key to exit . . ." or whatever.

Code
while (!kbhit());
remember to include conio.h (though mine has it in stdio.h also).
None.
The "alt + F5" didn't work. I opened my file "Project 1" and then went to the left side tree and clicked on the main.cpp file and then went to the right side and copy and pasted the code you provided, hit alt + F5 and nothing happened. 
None.
Ctrl + F5
None.

WoAHordeYou want a cin.get(); instead of a return 0; so the program remains open.
This only works once until you hit a key or type something in followed by the enter, then the message comes back up again. Is there some number that I am supposed to input into the "()" area to make it last forever?

<3 YEAH! It worked! Now all that I have to do is learn some code that can actually be used for something decent and BAM! Is there a list somewheres that has every code with what it does? *Starts to Google*

You don't want it to continue when you hit enter?

Umm, that would be one HUGE list. Depends on what libraries you are using.

I want it to be able to stay open even after you enter commands, valid or not valid.
I would just want a basic list of code so that I can familiarize myself with it.
None.
Use a while loop then.
None.
Code
// While loop example
#include <iostream>
using namespace std;
int main ()
{
int a,b,c;
a = 1;
cout << "Go" "\n";
cin>> c;
cin.ignore();
while (a==1)
if (c==1) {
cout << "Input a number to be cubed." "\n";
cin>> b;
cout << b * b * b "\n";
cin.get();
cout << "Press 1 if you wish to go again" "\n";
cin>> c;
cin.get();
}
else if (c > 1, c < 1) {
return 0;
}
}

What is with C and using >> and << as syntax 
Also, I assume that
is equivalent to

EDIT:
Forgot to include the fix to the other error message.
You need a closing brace "}" for the main() function, which you probably deleted by accident somehow.

Code
cout << b * b * b "\n";
should be replaced with this: Code
cout << b * b * b << "\n";
