The C Programming language doesn't actually support inheritance, it only supports composition. However, the following code demonstrates how we can use composition to approximate single inheritance:
struct Base {
int data;
};
struct Derived {
struct Base base;
// ...
};
int main (void) {
struct Derived d;
d.base.data = 42;
return 0;
}
What else can I help you with?
What is an inheritance Explain different types of inheritance in c?
C is not an object oriented language and therefore has no native support for inheritance.
Why is multiple inheritance not possible in C?
C is not object-oriented -- you can't even use single inheritance let alone multiple inheritance.
How do you create multiple inheritance in c?
You don't. Inheritance is a feature of object oriented programming languages. C is not object oriented.
What is a relationship in following a-polymorphism b-inheritance c-overloading d-none of these options?
Inheritance.
What does staples mean by unwieldy inheritance?
mean an inheritance that is too heavy to bear.
How ploymorphism and inheritance is different from that in Java and c plus plus?
C++ allows multiple inheritance while Java does not. In my opinion, multiple inheritance is not useful because it can get very confusing very quick. For polymorphism, C++ does early binding by default, while Java does late binding by default. Late binding is more useful than early binding.
Specification forms of inheritance in java?
single level inheritance eg ( class B extends Class A) Multilevel inheritance eg( class C extends class B and class B extends class A) multiple inheritance Class C inherits Class A features as well as Class B featues.This type of inheritance is not allowed in JAVA.
Does c plus plus supports hierarchical inheritance?
Yes.
What is multiple inheritence in c?
C is not object oriented and therefore has no concept of inheritance of any kind.
What is the difference between class inheritance and interface inheritance?
interface inheritance is a misleading term. Interface inheritance would be equivalent to the union of the method signatures of interfaces ( no typo here, an interface may implment multiple other interfaces) Class inheritance - single hierarchy (in C#), and not only the methods are inherited, but also the data members. (interface in C# cannot define data members)
What is problem in multiple inheritance?
Java does not support direct multiple Inheritance. Harder to implement, not every language support it: C++ does, Java does not.
Type of inheritances in c plus plus?
Single, multiple, multi-level, hierarchical and hybrid/virtual inheritance. Single inheritance applies when one class inherits from just one base class. Multiple inheritance applies when one class inherits from two or more base classes. Multi-level inheritance applies to a class that inherits from at least one base class that is itself derived from another base class. Hierarchical inheritance applies to a base class that is inherited by two or more separate derived classes. Hybrid inheritance combines multiple inheritance, multi-level inheritance and hierarchical inheritance. That is, where A is a common base class of derived classes B and C, and B and C are both base classes of derived class D. Hybrid inheritance is often used with virtual inheritance where B and C inherit from A virtually rather than directly. In these cases, the virtual base class is instantiated by the most-derived class in the hierarchy, D, and this instance is then shared by both B and C.
