Question

What are the pros and cons of dynamic binding?

a) Flexibility and late binding; Cons: Performance overhead and potential runtime errors
b) Early binding and improved performance; Cons: Limited flexibility and adaptability
c) Explicit type specification and compile-time optimization; Cons: Code verbosity and reduced adaptability
d) Simplified syntax and reduced compilation time; Cons: Limited runtime adaptability and increased debugging complexity

Answer 1

Dynamic binding offers flexibility and late method resolution, which provides an advantage in scenarios where objects of different types are used. However, it can introduce performance overhead and increase the risk of runtime errors since methods are resolved at run time rather than compile time.

Step-by-step explanation:

The question is regarding the pros and cons of dynamic binding in programming. The correct answer is: Pros: Flexibility and late binding; Cons: Performance overhead and potential runtime errors.

Dynamic binding, also known as late binding, allows a program to decide which method to call at runtime instead of at compile time, which is referred to as early or static binding. This feature adds flexibility to programming, as objects of different types can be processed more generically at runtime. However, this flexibility comes with certain drawbacks, such as performance overhead because the method call resolution happens at runtime, which can be more time-consuming than at compile time. Additionally, since the binding occurs late, there is a risk of runtime errors if the correct method cannot be found, which might not be detected during compile time.
