    about constructors

    Hi Guys,

    I wanted to know that can we have default constructor and also a parameterized constructor for the same class ?

    eg:

    Code:
    ----------------------------
    class Student
    
    {
    
    private:
    char Name;
    int age;
    
    public:
    
    Student(); //default constructor/
    
    Student(char Name ,int age)  //constructor with parameters/
    
    void getName();
    void getage();
    
    };
    ----------------------------------

    Have I written the parameterized constructor correctly?

    Thanks

    Wow, you have an amazing tendency to repeat same questions again and again!

    I think you haven't read this question carefully, I am asking that can we use "default constructor" and a "parameterized constructor" in the same class?

    I think you haven't read the answers you previously got carefully.

    Yes. It was implied in that other thread by me, then more directly by grumpy.

    I think that you need to learn C++ in a structured way, e.g., by working through a book.

    Laserlight,

    Thanks for your reply, well the post was long and I might have missed some points.

    No where in the post it answers my question clearly.

    My question was simple can I use both "Default Constructor" and "Parameterized Constructor" at the same time in the same class?

    If you can't help then pls don't show attitude.

    Nobody here is obliged to help you unless you yourself show some effort.

    Quoting grumpy's answer from your last thread:

    Quote Originally Posted by grumpy View Post
    It makes sense to overload a constructor if parameters of differing types can potentially used to create a whole object.

    Let's say int makes sense to construct an object from an integral value in some circumstances, and from a string of characters in other circumstances. Generally, it would then make sense to create two constructors, one that accepts an int, and one that accepts a const char *. I've illustrated this using constructors that only accept one argument, but the principle works if you need to construct objects from multiple items of data (i.e. multiple parameters to the constructor).

    I don't know whether it makes sense in your Vehicle class. In what ways does it make sense to construct a Vehicle?

    I wouldn't supply a default constructor for a class, unless it makes sense to create an object based on nothing (no parameters required).

    Don't read on unless you like technical pedantry. Technically, unless copy constructors (that create an object from an existing object of the same type) are disabled, all constructors are overloaded. The compiler will generate a copy constructor if the programmer doesn't, and it can. It doesn't make sense to have a copy constructor unless there is some other way to create an object to be copied - which means another overloaded constructor must exist. The only exceptions to this are if copy constructors are specifically suppressed.
    Look closely at the bolded regions.
    If that didn't answer your question, nothing but direct spoonfeeding will and you're out of you mind to demand it here.

    Well, you could have written as:

    "Your Question was answered in the previous posts "
    And you could have given the link of that post,alright, before calling me stupid you should see your face in the mirror ok.
    I am more smart then you, I am a human being and can make mistakes but it doesnot mean that you should show your attitude.

    You said:
    I have tendency of repeating the same question".


    Yes , I have faced many indians in my life, you guys are filled in Call Centers and donot provide proper service to anyone.

    Instead of complaining and showing attitude ,do something good in life.

    I don't want to argue here and I am here to discuss and learn thats it.

    I was not being rude to you but this is not how you reply.

    I can make mistakes as I have said before.

    You are a champion of programming right, I am new in programming but I don't show attitude ok.

    I am out of practice and have other work to do.

    I'll write it exactly as I want, not what you want as long as they convey the same message.

    And you could have given the link of that post,alright, before calling me stupid you should see your face in the mirror ok.

    Basically, you didn't understand grumpy's post, hence you should have sought clarification.

    Sorry, but this is simply unacceptable. This is an international forum; you do not have a free pass to get away with racism. This is an official warning. Note that if you accumulate three such warnings, you will likely be banned.
