My question is about overloading , can anyone tell me that is overloading possible in inheritance or not ? because when we declare a method in parent class let suppose xyz is my method and its return type is "int". if we declare the same method name in
the child class but its return type is string. This is possible we can do this but my question is "can we call this is overloading ?".
The answer is No. thats is function overloading means (as per wiki) "allows creating several
methods with the same name which differ from each other in the type of the input and the output of the function. It is simply defined as the ability of one function to perform different task".
In your case you are divided that function in 2 diff classes. So its not come under the overloading concept.
Thanks,
Happy to Help!

In my word, method overload means that two methods have the same name, but have different amount of the parameters or have different type of the parameters .
For example：
public class A
{
public int Add(int a, int b)
{
return a+b;
}
public int Add(int a, int b, int c)
{
return a+b+c;
}
// those two methods are overloading
}
public class B
{
public string Add(int a, int b)
{
return a+b;
}
public string Add(string a, int b)
{
return a+b;
}
// those two methods are overloading
}
public class C
{
public string Add(int a, int b)
{
return a+b;
}
public int Add(int a, int b)
{
return a+b;
}
// those two methods are not overloading
}

Hi francissvk,
I am sorry for the late reply.
Overload methods can have the same type of the output, but the different in the type and amount of the input.

I just create a simple example, please try to refer to:
namespace test
{
class A
{
public int add(int a, int b)
{
return (a + b);
}
}
class B : A
{
public string add(string a)
{
return a;
}
}
class Program
{
static void Main(string[] args)
{
A a1 = new A();
B b1 = new B();
b1.add("abc");
b1.add(1, 2);
a1.add(1, 2);
A a2 = new B();
a1.add(1,2);
}
}
}

my question is very simple and straight forward, overloading is possible in inheritance or not and if possible than what we will say ? because i read it that overloading is possible in same class but i practically do that overloading is also possible in
inheritance .

Hi,
In my mind, it is not possible.
Overloading is in the same class.
How do you do the overloading in inheritance?
