medium📝 Predict Output Q5 of Q15
Step-by-Step Solution
Solution:
Step 1: Understand method signature conflict
Two interfaces with same method name but different return types cause ambiguity.Step 2: Check C# rules for interface implementation
C# compiler cannot resolve which method to implement, causing compile-time error.Final Answer:
Compile-time error due to ambiguity -> Option AQuick Check:
Conflicting interface methods cause compile error [OK]
Quick Trick: Conflicting method signatures in interfaces cause compile errors [OK]
Common Mistakes:
MISTAKES- Assuming runtime error instead of compile error
- Thinking class can implement both methods without conflict
- Believing one interface method overrides the other silently
