How do memory management techniques differ between C and C++?
In C, memory management is manual, using functions like malloc and free. C++ offers both manual and automatic management with constructors, destructors, and smart pointers.
What are smart pointers in C++?
Smart pointers are objects that manage memory automatically. They help prevent memory leaks by ensuring that memory is released when it's no longer needed.
Can you explain the difference between unique_ptr and shared_ptr?
Sure! unique_ptr
is a smart pointer that owns a resource exclusively, while shared_ptr
allows multiple pointers to share ownership of a resource.
What happens if I forget to free memory in C?
Forgetting to free memory in C can lead to memory leaks, which may cause your program to consume more memory over time and potentially crash.
