What is object lifetime in C++?

What is object lifetime in C++?

Object lifetime in C++ refers to the duration during which an object exists in memory, from creation to destruction.

How does the scope affect object lifetime?

The scope determines when an object is created and destroyed. Objects created within a block are destroyed when the block ends.

Can you explain stack vs heap allocation?

Stack allocation is automatic and limited to the scope, while heap allocation is manual and persists until explicitly freed.

What happens if I forget to delete a heap-allocated object?

Forgetting to delete a heap-allocated object leads to memory leaks, which can exhaust memory resources over time.

Are there any tools to help manage object lifetime?

Yes, smart pointers in C++ like std::unique_ptr and std::shared_ptr help manage object lifetime automatically.
