hard📝 Application Q8 of 15

Kotlin - Data Types

ABy forcing you to write separate functions for each primitive type

BBy using a unified Number class that all numeric types inherit from

CBy requiring explicit casting to primitive types

DBy disallowing mixed numeric types in functions

Step-by-Step Solution

Solution:

Step 1: Recall Kotlin's numeric type hierarchy
All numeric types inherit from the Number class, which is an object type.
Step 2: Understand function parameter flexibility
You can accept Number type to handle Int, Double, Float uniformly without primitives.
Final Answer:
By using a unified Number class that all numeric types inherit from -> Option B
Quick Check:
Unified Number class enables generic numeric functions [OK]

Quick Trick: Use Number type to accept all numeric values [OK]

Common Mistakes:

MISTAKES

Thinking separate functions are needed
Assuming explicit primitive casting is required
Believing mixed types are disallowed
