I am trying to write a program that prompts the user for a value in degrees
and outputs the sine, cosine and tangent of the value entered. This is what
I did:

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

void main(void)
{


double degrees, cosine;


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

cin >> degrees;


cosine = cos(degrees*180/M_PI);


cout << "Cosine: " << cosine << endl;

cout << "Sine: " << sin(degrees*180/M_PI) << endl;

cout << "Tangent:" << tan(degrees*180/M_PI) << endl;
}

I want to include a sentinel loop to prompt the user repeatedly until the
user decides to stop. I need some help to do this. Will anyone help me?
