Fine video explaining the random facilities in C. In English, using the old ASCII representation is relatively easy, because the letters comes in a nice row. When using Danish, as I do, I could use the extended ASCII earlier, but now I had to face the dominating UTF8, which is compatible with ASCII, but using more bytes and the Danish letters does not come in a row. Maybe an idea to introduce UTF8 in a video, because as I understand, it's used almost everywhere...

Big fan of your teaching style and your voice also

Can we take advantage of the fact that each time our program runs the operating system will allocate a random space for our variables in the memory, so we can use these random memory addresses to generate random numbers like this : char random(){ long long random = (long long )&random; int value = (int) (random % 26 + 'A'); return (char) value; }

Please can you do a video like this but with cryptographically random integers? As an example in Go we have the crypto/rand package that uses under the hood urandom (native cryptographically number generator in Linux systems)

One day I would like to do a video on crypotgraphically secure random number generation. It's a big topic though with different approaches, it's tough to cover, though maybe I can cover one reasonable approach...

Hello, I'm your long time subscriber and viewer and I noticed that you do not have any nested programming in c such as nested loops nested for loop/while loop, please teach also them

Great idea Pls help us doing this sir . And one more question Why 1 is added when negative numbers shifting to right side What would be the reason . Will you pls help us doing a video on this Topic . Thanks you so much ❤.

Do you think this method of generating random characters is good to create passwords?

@mansbjork5721 10 ай бұрын

I think this might depend on whether this method generates random/pseudo-random numbers. To know this would inquire information about how time(), srand() and rand() operate.

no it's not, using rand() for anything involving cryptography is not safe
