in previous vdo u told that constructor never participate in inheritance but here u r dealing with inheritance

[@Impromptu21]

sir we got error piz help out using this code

[@naimahmed8495]

the lecture is very clear...for this reason it is very easy to understand...thanks sir for your kind help to understand briefly...

[@nikhilghorpade3048]

for those who are getting errors, plz use the below code for marks class class marks : public stu { int m,p,c; public: marks(char name[20], char course[20], int m ,int p, int c) : stu(name, course) // use this to pass name and course to student class constructor. { //stu::stu(name, course); //don't use this line this->m = m; this->p = p; this->c= c; } void showmarks() { cout

[@mohitsaud2071]

// Full code using devc++// #include #include #pragma GCC diagnostic ignored "-Wwrite-strings" using namespace std; class stu{ char name[20], course[20]; public: stu(){} stu(char name[20], char course[20]) { strcpy(this->name,name); strcpy(this->course,course); } void showstu(){ cout

[@kaulsambhav]

In class Marks while calling the Stu constructor the scope operator that you used gives error. It should be Marks :: Stu(name, course) instead of Stu :: Stu(name, course). It gives a constructor error for permission while compiling.

[@sadeeshkumarmsd]

Even though it is not giving correct answer sir

Sir what happen if in multiple level inheritance base classes have parameters than which statement in first line in derived class

[@smarttube1141]

error: cannot call constructor ‘marks::stu’ directly [-fpermissive]

[@VinayKumar-nv1it]

Same here

[@malli14nuk]

@@VinayKumar-nv1it ==> marks(args):Stu(args) { }

[@shashankojha3452]

after inheriting the base class into the derived class we do not need to use scope resolution operator for calling base class constructor. try using this class child(int c,int d):parent(c,d) { this->c=c; this->d=d; } what he has told is wrong.

constructor is used to make code easier, but during inheritance, I think it is best to use normal functions than constructors.

[@maheswarigorantlagari4354]

instead of defining syntax of parameterized why u can define data members in protective specifier.we can acess easy the stu members in marks

[@srishti5400]

this man has got ultimate oops riz literally the best

[@chandumadhumanthi9983]

Sir, initially u told that constructors never participate in inheritance but ur explaining using inheritance..

[@sudhansushekharpatra7168]

Yes........

[@sharath5796]

how did we access the private data mem of base class in der class constructor ? we have to declare it protected first right??!

[@tarunagarwal7748]

sir when program get compile they give the error in define base class constructor in derive class constructor and also in main function insde when we declaratio of object.

[@debasreebhattacharjee4387]

constructor use in inheritance?please reply

[@_nabin_8848]

you might encounter an error using the given code for that instead of calling the base class constructor inside the derived class constructor, you should call the base class constructor in the derived class using the member initialization list.

[@saikun0293]

Correct code is: class marks:public stu { int m,p,c; public: marks(char name[20],char course[20],int m,int p,int c):stu(name,course) { //stu::stu(name,course); this->m=m; this->p=p; this->c=c; }; void showmarks() { cout

[@gowthamvijayakumar9499]

Bro this is working , thanks

[@ajaykharat8689]

Parameterized Constructors Inheritance Rule in C++:- 1. Base class should have to contain a default constructor. 2. Base class parameterized constructor should have to invoked from inside the derived class parameterized constructor 3. Base class parameterized constructor should be the first statement in derived class parameterized constructor 4. Only one Base class constructor is called within derived class constructor.

[@anmolgupta7639]

Sir in this program stu::stu(name, space) have shown error while compilation... Help me to get it out.

[@shubhamransing]

Very important for me sir..

[@bishalhalder6640]

Error: Class marks:public stu{ int m,p,c; Public : Marks( char name[20], char course[20],int m ,int p,int c) { stu:stu(name,course) ; //here was the error // You can also write marks::stu(name,course) ; this->m=m; this->p=p; this->c=c; } };

Could you please edit the lecture number in order,

Nice sir

[@kumarshivam2010]

What is derived class object and base class object. I am not getting it.

[@AmanDeep-pi9pk]

derived class object means child class or sub class object like marks m in main()

[@Shiva_polishetty]

#include #include #include using namespace std; class base{ public: char name[20],course[20]; base() { cout

[@sheshukumarsugurthu8887]

Same problem Name and course not copied into this->name and this->course

[@sanjogshrestha1859]

@@sheshukumarsugurthu8887 /* here is the solution */ #include #include using namespace std; class base{ char name[20],course[20]; public: base() { cout

The program is running without default ctor too? and yes who r getting error...it is of actually calling base class ctor in derived class ctor, follow as marks( mntion argumnts) : stu(name,course) { Code.... }

[@SumantKumar-jn9fm]

Program is running without default constructor because you haven't declared default constructor in derived class, either declare in both or don't declare!!

[@krishnakumari3804]

Sir, while running this program it shows lot of errors
