Write a Fraction class. An example of a fraction is 1/2. Note that C/C++ will convert it to 0.5, but for this problem, it should still be displayed as 1/2. You should have at least the following two private member variables: numerator (top part), and denominator (bottom part). Overload the following operators: ==, +, << and >>. Also, implement the default constructor and a second constructor that takes two arguments for the numerator and the denominator. Make sure the denominator...
