What is the difference between free and delete in C?
An example of an AI chatbot conversation about memory management in C programming.
What is the difference between free and delete in C?
In C, 'free' is used to deallocate memory that was previously allocated with malloc, calloc, or realloc. 'delete' is not used in C; it's a C++ operator.
Can you explain how free works with malloc?
Sure! When you allocate memory using malloc, it reserves a block of memory. You must use free to release that memory when you're done to avoid memory leaks.
What happens if I forget to use free?
If you forget to use free, the allocated memory remains reserved, leading to memory leaks, which can exhaust memory resources over time.
Is there a difference in usage between free and delete in C++?
Yes, in C++, 'delete' is used to deallocate memory allocated with 'new', while 'free' is still used for memory allocated with 'malloc'.
