Understanding Deallocate in C: How to Release Memory Effectively

Deallocate is a function in C that is used to release memory that was previously allocated with the `malloc` function. It takes a single argument, which is a pointer to the memory block that should be released. When you call `deallocate` with a pointer to a memory block, it will free up the memory and make it available for other uses.

Here's an example of how you might use `deallocate` in your code:
```
int *ptr = malloc(10 * sizeof(int));
// Use the memory block here...
deallocate(ptr);
```
In this example, we first allocate 10 bytes of memory using `malloc`, and then we use the memory block to store some data. Finally, we call `deallocate` with the pointer to the memory block to release the memory and make it available for other uses.

It's important to note that if you try to access memory after it has been deallocated, you may encounter unexpected behavior or crashes. This is because the memory has been released back to the system, and it may be reused for other purposes. Therefore, it's important to only use memory while it is still valid, and to release it properly when you are finished with it.
