IN C++ THANK YOU!

Lab 4.1 Utilizing the code from Lab 3.2, add an overloaded operator == which will be used to compare two objects to see if they are equal. For our purposes, two objects are equal if their abbreviation and uldid are the same. Youll need to make your overloaded operator a friend of the Cargo class. Create a unit1 object and load it with this data: uld Pallet abbreviation PAG uldid PAG32597IB aircraft - 737 weight 3321 Kilograms destination SEA Make a copy of unit1 called unit2 utilizing a copy constructor. Create a default unit3. Test with code like this in main: if (unit1 == unit2) cout << " unit1 is the same as unit2 "; else cout << " unit1 is not the same as unit2 "; if (unit2 == unit3) cout << " unit2 is the same as unit3 "; else cout << " unit2 is not the same as unit3 ";
