Use object oriected programming to solve this: The default values of the constructor in fraction.h ensures that the user cannot create fractions having denominator 0. This is the case, when an object is instantiated using the default constructor. Such an object “x” is instantiated in the main function. However, when the default constructor is not called, user can instantiate objects with the value of denominator equal to zero. See the instantiation of objects “y” and “z” in main.cpp. Your task is to make sure that the user cannot instantiate a fraction having denominator 0 using exception handling. There is ample space given in the above code. Donot rewrite the code, only add appropriateexception handling statements wherever required in the code given below. fraction.h fraction.cpp main.cpp class fraction { intnum; int den; public: fraction(int n=0, int d=1); ~fraction(void); }; #include "fraction.h" #include using namespace std; fraction::fraction(int n, int d) { num = n; den = d; } fraction::~fraction(void) { } #include #include "fraction.h" using namespace std; int main() { fraction x; // x = 0/1 fraction y(2,0); // y = 2/0 fraction z(0,0); // z = 0/0 return 0; }
