memory Variable

[Fushiguro19]

In the video, around 3:15:45, he says that if we write SimpleStorage in front of the variable simplestorage, it becomes a memory variable. I don't get it. Can someone plz explain it to me?? Thanks !!

@Fushiguro19 Yes, he created a SimpleStorage object there, and because that object will destroy at the end of createSimpleStorage function that is why it is a memory variable.

Ahh yes but what if we don't write SimpleStorage there? Will it still remain a memory variable as it will get destroyed as soon as the function ends? The impression I got was that if he hadn't written SimpleStorage there, then the variable would not have been a memory variable.... is it so?

@Fushiguro19 See in solidity, you need to mention the type of the variable/object. If you do not assign it, it will give an error. You can do this instead simpleStorageArray.push(new SimpleStorage());.

2 seconds before the timestamp you provided, Patrick declared the variable type outside the function scope that was not a memory variable because it did not gets destroyed at the end of function execution.
