Objectives :

  • myConstructDeclDef1.cpp
    class myConstruct2
    private: int n1;
    myConstruct2():n1(200){ cout<<"\n \t \b what is mc1 " <<n1; }
    //declared copy constructor
    myConstruct2(myConstruct2 &arg, int n2);
    //defining copyconstructor and integer parameter
    myConstruct2::myConstruct2(myConstruct2 &arg, int n2):n1(n2)
    cout<<"\n myConstruct2::myConstruct2";
    cout<<"\n \t \b (myConstruct2 &arg, int n2):n1(n2) "<< n2;
    cout<<"\n \t \b private integer refreshed n1 " << n1;
  • constructor declared and defined separately outside the class braces.
  • code: myConstructDeclDef1.txt
