Question: 1 / 565

What coding practice helps in changing the internal workings of a structure without affecting client code?

Hard coding values

Constant refactoring

Using the #define preprocessor directive

Encapsulation

Encapsulation is a coding practice that helps in changing the internal workings of a structure without affecting client code. This is because encapsulation allows for the hiding of implementation details and only exposes the necessary information, thus preventing the client code from breaking when internal changes are made. A is incorrect because hard coding values can make it difficult to modify the code in the future. B is incorrect because constant refactoring deals with making continuous improvements to the code, not necessarily preventing changes from affecting client code. C is incorrect because using the #define preprocessor directive can only define a macro, not encapsulate code.
