#include using namespace std;
class InchSize {
public:
InchSize(int wholeInches = 0, int sixteenths = 0);
void Print() const;
InchSize operator+(InchSize rhs);
private:
int inches;
int sixteenths;
};
InchSize InchSize::operator+(InchSize rhs) {
InchSize totalSize; //this line
totalSize. inches = inches + rhs. inches; //this line
totalSize. sixteenths = sixteenths + rhs. sixteenths; //this line
// If sixteenths is greater than an inch, carry 1 to inches.
if (totalSize. sixteenths >= 16) {
totalSize. inches += 1;
totalSize. sixteenths -= 16;
}
return totalSize;
}

can anyone explain how these lines work? I am confused on how "InchSize totalSize;" is used.
