Solution

Dynamic Memory Allocation is like asking for extra space when you need it while doing a task.

Let's break it down:

  1. Request for Space: Imagine you're organizing a party and you're not sure how many guests will come. So, you start with a small room. But as more guests arrive, you realize you need more space. This is like a program asking for more memory space when it's running and realizes it needs more.

  2. Getting the Space: Now, if there's an extra room available, you can use it for your party. Similarly, if the system has enough memory available, it gives (allocates) it to the program.

  3. Using the Space: Just like you use the extra room to accommodate more guests, the program uses the allocated memory to store and manage more data.

  4. Freeing up the Space: After the party, you clean up and free the room so it can be used for other purposes. Similarly, once the program is done using the extra memory, it should release (deallocate) it so that it can be used by other programs.

So, Dynamic Memory Allocation is the process where a running program asks for more memory space as it needs, uses it, and then releases it when it's done.
