Question

Which programming language doesn't use a garbage collection because, at compile time, it can tell if a variable is no longer in scope and uses lifetimes to keep track?

A) Java
B) C++
C) Python
D) Go

Answer 1

The programming language that relies on scope and lifetimes instead of garbage collection for memory management is C++, which allows developers to manually control object lifetimes for more efficient memory usage.

Step-by-step explanation:

The programming language that doesn't use a garbage collection and instead relies on scopes and lifetimes to manage memory is B) C++.

Unlike languages such as Java or Python, which have a garbage collector to automatically manage memory, C++ uses deterministic destruction, where the developer must handle object lifetimes manually. C++ allows for fine-grained control over resources, which can lead to more efficient memory usage if used correctly. However, it also means that developers must be careful to avoid memory leaks and other related issues that more modern garbage-collected languages protect against.
