C++ :

Complete the implementation of the given Fraction class

Notes :

You are not allowed to make any change to the given Fraction class.

make sure that there is NO common factors between *numerator and *denominator.

if the Fraction is negative, the negative sign always goes to *numerator , *denominator always greater than or equal to 1 .

for the output operator << ,

if *denomiator is equal to 1 , the denominator will not be displayed. (i.e. 2 instead of 2/1 )

if the Fraction is negative, make sure that negative sign always goes with numerator ( i.e. -2/3 instead of 2/-3 )

use the given driver to test your code.

You must put the Fraction class and its implementation in separate files named Fraction.h and Fraction.cpp .

Fraction class:
