Define a private helper function called ConvertToPints() that converts the data member gallons to pints and returns a double.

Ex: If the input is 240.0, then the output is:

1920.0 pints
Note: The equation to convert from gallons to pints is: pints = gallons * 8

#include
#include
#include
using namespace std;

class Volume {
public:
void SetGallons(double volumeGallons);
double GetGallons() const;
void PrintInPints();
private:
double gallons;
double ConvertToPints();
};

void Volume::SetGallons(double volumeGallons) {
gallons = volumeGallons;
}

double Volume::GetGallons() const {
return gallons;
}

/* Your code goes here */

void Volume::PrintInPints() {
cout << fixed << setprecision(1) << ConvertToPints() << " pints" << endl;
}

int main() {
Volume volume1;
double inputGallons;

cin >> inputGallons;
volume1.SetGallons(inputGallons);

volume1.PrintInPints();

return 0;
}

Answer 1

The question requires the definition of a private helper function named ConvertToPints() within a Volume class which multiplies the volume in gallons by 8 to give the equivalent volume in pints.

Step-by-step explanation:

The question is asking to define a private helper function within a Volume class in C++ that is designed to convert gallons to pints. The private function, named ConvertToPints(), should take no arguments and return a double representing the number of pints.

Here is an example definition of the requested function:

double Volume::ConvertToPints() {
return gallons * 8;
}

This function assumes that the gallons data member is already set to the correct value when the function is called. An input of 240.0 gallons would then yield an output of 1920.0 pints, which is derived from the conversion where 1 gallon equals 8 pints.
