Questions and Answers

What is the purpose of adding a generic function to the code?

To replace all existing functions with a single, more efficient function
To limit the functionality of the function to only one specific data type
To enable the function to work with both integer and float values using type parameters (correct)
To complicate the code structure by introducing unnecessary constraints

Why is it important to specify the type parameters when calling the generic function?

To make the code more complex and difficult to understand
To improve the performance of the function at runtime
To prevent the code from compiling successfully
To inform the compiler about what types should be used in place of the type parameters (correct)

What happens if the type argument provided during function call is not allowed by the type parameter's constraint?

The code won't compile (correct)
The function will ignore the constraint and execute normally
The code compiles successfully but produces incorrect results at runtime
The compiler automatically adjusts the type argument to match the constraint
