Need C++ code for below

Write a program that will output the sum of two quadratic polynomials. Your program must do the following: 1. Define an abstract data type, Poly with three private data members a, b and c (type double) to represent the coefficients of a quadratic polynomial in the form: ax^2 + bx + c 2. Include a constructor in the Poly class to initialize all private data members with caller-supplied values (in addition to the default constructor!) 3. Overload the addition operator to return the sum of two Poly objects. 4. Overload the
