Final answer:
It is true that client code should not be aware of the representation type in software engineering. This promotes encapsulation and supports modular and maintainable code by concealing internal data structures.
Step-by-step explanation:
True: In software engineering, keeping the representation of data hidden from the client code (i.e., encapsulation) is generally considered good practice. This principle is often related to the concept of information hiding, which dictates that the internal representation of an object should not be exposed to the outside to ensure loose coupling and high cohesion within code. The benefit lies in the ability to change the internal representation without affecting the code that uses the object. For example, if a Java class is used to implement a stack, then whether the stack is implemented using an array or a linked list should be hidden from the user of the class. This approach allows for improvement or optimization of the class internals without disrupting the code that depends on it.
