Given the following class definition: class Rectangle{  private:    double width;    double height;  public:    void setWidth(const double w);    void setHeight(const double h);    double getWidth() const;    double getHeight() const;}; Write the complete definition of the member function getWidth that includes the function header and code to implement the function.

Why should you not compare variables of type double using the == operator?

Consider the following code using constants that calculates the speed of a falling object as a function of how long it has been falling:  const double GRAVITY; // acceleration [m / s^2] double time(10.0); // time, in sec cout

What is the value of x after the code below finishes? int x = 3;x = x — + — x; Do this calculation by hand. Do NOT use paper/pencil or a compiler.

What is the return data type of the following function header (also called prototype)? bool relatively_prime(int k, int l);

Consider the following code using constants that calculates the speed of a falling object as a function of how long it has been falling:  const double GRAVITY(9.8); // acceleration [m / s^2] double time(10.0); // time, in sec cout

In what order will the four math functions execute in the following expression ? cos(5.1 + sin(2.2 + 3.0 – 1.0) * 6.0) / 4 + log(3.5 + sqrt(27.0)) * 2 For example, your answer for the expression: sin(10.0) + cos(5.0) would be sin 1st, cos 2nd because the sin function will execute before the cos function.
