In this assignment you are required to complete a class for fractions. It stores the numerator and the denominator, with the lowest terms. It is able to communicate with iostreams by the operator << and >>. For more details, read the header file. //fraction.h #ifndef FRACTION_H #define FRACTION_H #include <iostream> class fraction { private: int _numerator, _denominator; int gcd(const int &, const int &) const; // If you don't need this method, just ignore it. void simp(); // To get...

The code should be written in C++. I included the Class used for this function. Also, please fix the main function if necessary. Description: This function de-allocates all memory allocated to INV. This will be the last function to be called (automatically by the compiler) //before the program is exited. This function also erased all data in the data file. There are other functions that add, process and alter the file; the file printed after those functions will have new...
