Question

What is CBO in the context of object-oriented systems?

a.

The main coupling metric for object-oriented systems

b.

The distance of a class to the root of its inheritance tree

c.

The number of immediate descendants of a class

d.

The complexity of a method

Posted under Software Engineering

Answer: (a).The main coupling metric for object-oriented systems Explanation:CBO stands for "Coupling Between Objects". It is defined as the main coupling metric for object-oriented systems, and it counts the number of other classes with which a class is coupled. Two classes are considered coupled if a method of one class uses a method or state variable of the other class. A high value of CBO suggests tight bindings with other components, which is considered undesirable in object-oriented design.
