Answer the questions about the Temperature class definition shown below:

class Temperature {

public:

Temperature ( ); // POST: object has 0 C

void setTemp (double value); // POST: set the Celsius temperature

double getTemp ( ); // POST: return the Celsius temperature

double convert ( ); // POST: return the Fahrenheit equivalent

bool operator == (Temperature other);

// POST: return true if object and other have the same temp

private:

double temp; // temperature stored in Celsius units

};
