[Solved] Find the problem in this code:class Base { public virtual void Print() { } } class Derived : Base { public override void Print(int x) { } } | C Sharp (C#)

C Sharp (C#) - Polymorphism and Abstract Classes

Find the problem in this code:

class Base {
    public virtual void Print() { }
}
class Derived : Base {
    public override void Print(int x) { }
}

AMethod signature mismatch; cannot override with different parameters.

BBase method should be abstract.

CDerived method should be virtual.

DNo problem; code is valid.

Step-by-Step Solution

Solution:

Step 1: Compare method signatures
Overriding requires exact signature match; Print() vs Print(int x) differ.
Step 2: Identify signature mismatch error
Derived method is not overriding but overloading; compiler error occurs due to override keyword with different signature.
Final Answer:
Method signature mismatch; cannot override with different parameters. -> Option A
Quick Check:
Override requires exact signature match [OK]

Quick Trick: Override needs exact method signature match [OK]
