First Exercise:

    classFather { Public stringLastName {Get;Set; }  Public decimalProperty {Get;Set; }  Public stringBloodtype {Get;Set; }  PublicFather (stringLastName,decimalPropertystringbloodtype) {             This.

    classSon:father { Public stringName {Get;Set; }  PublicSon (stringLastName,decimalPropertystringBloodtype,stringname):Base(LastName, property, Bloodtype) { This. Name =name; }         Public voidPlayGame () {Console.WriteLine ("son loves to play games"); }    }

    class Daughter:father    {        public daughter (stringdecimalstring  bloodtype)              Base (LastName, property, Bloodtype)        {        }        publicvoid  Dance ()        {            Console.WriteLine ("  daughter loves to dance ");}    }

A second exercise:

Brand =brand;  This. Color =color; }         Public voidRun () {Console.WriteLine ("cars will run ."); }        //Public void SayHello ()//{        //    //Console.WriteLine ("I am {0} car, I am {1} color", this.) Brand, this.        Color); //}         Public Virtual voidSayHello () {}}

    classtruck:vehicle {Private int_weight;  Public intWeight {Get{return_weight;} Set{_weight =value;} }         PublicTruck (stringBrandstringColorintweight):Base(brand, color) { This. Weight =weight; }         Public Override voidSayHello () {Console.WriteLine ("I am the {0} card {1} color truck, payload {2} ton", This. Brand, This. Color, This.

    classcar:vehicle {Private int_passenger;  Public intPassenger {Get{return_passenger;} Set{_passenger =value;} }         PublicCar (stringBrandstringColorintpassenger):Base(brand, color) { This.
