I am making a list of trig functions by increments of 10 degrees and I dont have a complier.

include <iostream.h>
#include <math.h>

void main

float degrees, Sin, Cos, Tan;

cout << "Enter a number of degrees: ";
cin >> degrees;


cos = cos(degrees*180/3.14);

cout << "Cosine: " << cosine << endl;
cout << "Sine: " << sin(degrees*180/3.14);
cout << "Tangent:" << tan(degrees*180/3.14);

do {

	cout << "Enter degrees: ";
	cin >> degrees;
	cout << "Sin";
	cin >> sin;
             cout << "Cos";
	cin >> Cos;
             cout << "Tan";
	cin >> Tan;


	counter = degrees;
	cout << setw( 10 ) << "Degrees"
			<< setw ( 20 ) << "sine"
			<< setw ( 20 ) << "cosine"
			<< setw ( 20 ) << "Tangent"
			<< "\n";
	while( counter <= Sin, Cos, Tan)
		{
	  cout << setw( 10 ) << degrees
			<< setw ( 20 ) <<  sine, cosine, tangent
			<< "\n";
	  counter = counter + 10;

	 }// end while
		  cout << "\nDo you want to do this again?(y/n) ";

}// end main

<< moderator edit: added code tags: [code][/code] >>

im hoping it looks likes this:

Degrees Sin Cos Tan
0 0 0 0
10

I suggest you get one, because your code will not compile. Or at the very least, you can test drive Comeau here to see what the errors would be.
