All I'm saying is any language that lets you write to the 51st element of a 50 element array needs to be treated with caution and respect, like a seven-round revolver or a tablesaw without a sawstop.

I'm not a professional programmer, does this return an exception, try to write the entry and submits it to a void never to be seen again, crash the program, overwrite another vital piece of data?

In C/C++, there's not a whole lot of anything approaching rails in the language. You can absolutely write off the end of an array, clobbering other data, which may or may not have an effect, depending on what's in RAM directly after that array. That's why C++ is both 1) Powerful and good and 2) a dangerous weapon. Specifically, a lot of bugs are introduced because of the historical and technological reasons that the last element of an array of 50 items is item 49.

Yeah, you'd get an ArrayOutOfBounds exception in most languages. Don't get me wrong, I'm not saying C or C++ are BAD. They're DANGEROUS. Knives aren't BAD, they're DANGEROUS, but also extremely useful and powerful. C and C++ are the same way.

Arrays are dangerous tools used too often for subversive purposes. You should need an array license else you must operate on well defined variables like a normal person. Tables in code and volatile memory should be internationally banned.

In case you're not a programmer: A less volatile language like C# (that won't let you shoot yourself in the proverbial dick) will typically run WAY slower due to the overhead necessary for the aforementioned "rails".

The whole program becomes invalid. It is even allowed to do the wrong thing before the out-of-bounds write actually happens. (No, I’m not even going to try explaining. Look up "undefined behaviour" on YouTube if you really care.)

Aren't languages like Go or Rust almost as fast as C(++), but memory safe? (not a programmer, but i spend enough time online to absorb some of the concepts)

Rust can, but it's not easy to catch up to institutional knowledge, inertia, libraries etc that exist for C/C++, especially in heavily regulated industries. Speed wise there isn't much difference between them, but it depends heavily on what you're doing with the languages. Lots of new languages now are just frontends for LLVM, which can perform similar levels of optimization that you'd see in C/C++.

In c++ most container classes will throw a an index out of bounds exception but c++ arrays are just TxN ram where t is the type of object on the array and N is the number of objects in the array. Later languages use array more of a class. Don't ask me to get deeper this is, ironically, the limit of my understanding

Wasn't there a nft or coin knock off that had all of the transaction functions public and also because the way these work is they have to execute some code so if you clicked on an nft it drained your wallet

I thought there was something involving a "smart contract" where people did in fact get their wallets drained by clicking something. I don't know, though - the number of scams and rugpulls and frauds in the crypto space makes my memory a little hazy.

If I need performance and low overhead for, like, 3D stuff or whatever, I'll use C++. Otherwise I usually use C# because it really doesn't matter that my dinky little programs run less efficiently when they're doing poo poo that is done quicker than blinking anyway. Now I'm trying to get the blockchain happening but so far all over managed is to drag my computer behind my truck on the highway (the block and chain in question) but it doesn't seem much better???

One scam that kinda worked like this is that you are able to authorize certain accounts to manage your NFT on your behalf - that is how the auction sites and stuff work. So a scam would be to make it seem like you authorize an account to manage one NFT, while in reality you authorize it to manage another. Since most "smart contract" stuff is run through a javascript plugin called Metamask, there were tons of ways to fool people into clicking links they shouldn't have clicked. But clicking an NFT in your collection wouldn't trigger any of that code, it would just go to the summary page for that NFT.

Wouldn't it be a simple matter for the real Satoshi to prove his identity because he alone can make transactions with the huge untouched pile of bitcoin he pre-mined. Like why is that not the test: "ok if you're telling the truth, send one of Satoshi's bitcoins to a new wallet and back again"

Satoshi's dead. Crushed when one of the piles of bitcoins in his house collapsed. Happened nearly ten years ago, must be pretty skeletonised by now.
