Dynamic memory

Alright kiddo, so when we want to store information in a computer program, we need to use something called "memory". Think of it like a very big box with lots of little compartments where we can put stuff in and take it out when we need it.

Now sometimes we don't know exactly how much information we will need to store in advance. For example, if we are making a game and we don't know how many players will be playing or how many items they will collect. In these cases, we need to use "dynamic memory".

Dynamic memory is like having a special part of the memory box where we can add or remove compartments as we need them. So if we need to store more information, we can just add a new compartment. And if we don't need one anymore, we can remove it.

However, adding and removing compartments can be tricky. We need to make sure we don't accidentally remove important information or create too many compartments and run out of space. That's why we need to be very careful and use special commands to manage our dynamic memory.

It's kind of like playing with Lego blocks. Sometimes we need to build a big structure and we don't know exactly how many blocks we need in advance. So we start with a few blocks and add more as we need them. And when we're done, we can take the blocks apart and put them back in our Lego box, just like how we can add or remove compartments in our dynamic memory.
