Chapter 3.7, Problem 3.23CP

The following program segment converts an angle in degrees to radians.

const double PI= 3.14159;

double degrees, radians;

cout << "Enter an angle in degrees and I will convert it\n";

cout << "to radians for you: ";

cin >> degrees;

radians = degrees* PI / 180;

// Display the value in radians left-justified, in fixed-point

// notation, with four decimal places of precision, in a field

// seven spaces wide.
