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

C Sharp (C#) - Inheritance

Find the problem in this code snippet:

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

ADerived.Print must have same signature as Base.Print

BBase.Print must be abstract

CDerived.Print should be static

DNo problem, code is valid

Step-by-Step Solution

Solution:

Step 1: Check method signatures for overriding
Overriding requires method signatures to match exactly (name and parameters).
Step 2: Identify signature mismatch
Derived.Print has an int parameter, Base.Print has none, so this is method overloading, not overriding.
Final Answer:
Derived.Print must have same signature as Base.Print -> Option A
Quick Check:
Override requires matching signature [OK]

Quick Trick: Override methods must match base method signature exactly [OK]
