Final answer:
Designing software by assigning responsibilities to objects means breaking down the software into smaller, manageable parts where each object has a specific task or responsibility.
Step-by-step explanation:
The idea of designing software by assigning responsibilities to objects means breaking down the software into smaller, manageable parts where each object has a specific task or responsibility. This approach is known as object-oriented design, which is used in languages like Java, C++, and Python.
For example, let's say you are designing a car simulation software. In an object-oriented design, you would create objects for different components of the car such as the engine, steering wheel, and brakes. Each object would have its own responsibilities and interact with other objects to perform the desired functionality.
