What are the common memory management functions in C?

In C, the common memory management functions include malloc, calloc, realloc, and free. Would you like to know how each one works?

Yes, please explain how malloc works.

malloc allocates a specified number of bytes in memory and returns a pointer to the first byte. It returns NULL if the allocation fails.

What about calloc? How is it different from malloc?

calloc allocates memory for an array of elements, initializes all bytes to zero, and returns a pointer. It's useful when you need zero-initialized memory.

Can you explain realloc as well?

realloc changes the size of previously allocated memory. It can increase or decrease the size and may move the memory block to a new location.
