Question: 1 / 565

What problem do templates solve compared to inheritance and composition?

Slow compilation

Code reuse without loss of type information

Templates allow for generic code to be written, without losing type information, and reused in various contexts without the need for inheritance or composition. Option A is incorrect because templates can in fact improve performance by allowing for code to be generated at compile-time rather than run-time. Option C is incorrect because templates do not solve memory management issues, rather they can potentially cause them due to the need to instantiate new objects. Option D is incorrect because templates do not result in encapsulation violations as the code inside the template remains inaccessible to external sources.
