C++

Exercise :- Read the documentation of the header file carefully. Four of the function

implementations have documentation and the others do not. Explain how these four

are different.

Exercise :- Fill in the missing code in the implementation file, and compile

fraction.cpp. Were there many bugs in your file? Describe any problems that you

had.

Exercise :- Write a driver that uses class Fraction to do the following calculations:

1/2 + 1/4

1/2 1/4

1/2 * 1/2

1/2 / 1/2

Write the output clearly labeled.

// Header file fraction.h declares class Fraction.

class Fraction

// Class Fraction represents the numerator and

// denominator of a fraction.

{

public:

// Constructors

Fraction();

// Post: Numerator and denominator have been set to zero

Fraction(initNumerator, initDenominator);

// Post: Numerator has been set to initNumerator;

// denominator has been set to initDenominator.

Fraction Add(Fraction frac1) const;

// Post: self + frac1 is returned.

Fraction Subtract(Fraction frac1) const;

// Post: self - frac1 is returned.

Fraction Multply(Fraction frac1) const;

// Post: self * frac1 is returned.

Fraction Divide(Fraction frac1) const;

// Post: self / frac1 is returned.

int GetNumerator() const;

// Post: Numerator of frac1 is returned.

int GetDenominator() const;

// Post: Denominator of frac1 is returned.

int numerator;

int denominator;
