could you do a tutorial on how to delete a row / entry from a file please 🙏☺

[@cipherion]

Code change: void readFileText(std::string myFileChoice) should have been coded as : void readFileText(const std::string& myFileChoice) so it isn't a copied string causing a heap allocation and therefore running much slower and taking up more memory.

[@appiahgideon213]

thanks for this video, I've learned a lot from it

[@tigergumby]

You described how to do all this in 20 minutes, what my school book took a million pages to describe. (Give or take a few hundred thousand pages.) Thank you!

Exactly! Took me ages to try and work this out then I realised why don't I just find a codebeauty video hahaha

Hey I commented in your last video and I said I was going to have a exam in c++ . I managed to get a 10/10 max score, thank you very much for helping me personally it was such a great journey through these series.

[@luxis_2295]

I’ve been having the doubt of how read and write from a file for weeks because my programming professor did not explained as good as you. You were the light that lit the way for me because I needed it for a project. Thank you Saldina!!

[@CodeBeauty]

You're very welcome! Glad I could help! 🥰🥰

[@edinfific2576]

In order to explain something, a person needs to have both a good knowledge and understanding of what they're explaining AND an ability to bring that understanding down to a comprehensible level or, in other words, to bridge that gap between deep understanding and no idea about how something works. Many teachers and professors seem to lack either one, two or all of the three qualities above.

[@priyanshusaxena7157]

My solution for the 1st challenge, converting a story to cipher and deciphering back the code in the console: #include #include #include using namespace std; int main() { fstream Myfile; // Taking the input string from the user string story; cout

[@hbm293]

I think you can skip the "Converting the string to character array" part, as a string is basically already a character array (and there are ways to iterate over each character contained in the "string" object, as you also have used, so you could use directly that when you do the "int(...)" cast when writing into your file ). Also it's funny that since you concatenate the numbers in the file without any (non-number) separators between each of them, then when you read back your file you need to do the funny calculation.

[@Ozonised]

Hey just wanted to say thank you :) Your formula for deciphering the text helped me a ton. I was stuck getting my program to decipher the text but thankfully I discovered your comment and so the formula which provided a ton of help :)

[@tapansonak1431]

Hi can anyone explain me the working of the decypher loop. I am not quite getting it. I didn't get the formula num = num * 10 + (line [i]- '0');

[@ahmedassal8710]

could you explain the formula num = num * 10 + (line[i] - '0' );

[@jiimmyyy4929]

Hey bro your code is awesome...Could you explain the calculations for the deciphering pls

[@potatoitis3326]

Saldina thank you for making this concept easier to understand. You are definitely an inspiration and I hope to be as great at programming just like you someday.

[@hbm293]

3:20​ @CodeBeauty Yes the ".txt" extension is just to make Windows' shell use whatever default program to open these text files. But otherwise, any extension is good as well. The important point however is that, used as such, the fstream::open() function opens files in **text mode** by default, unless one ORs the second parameter (the mode) with ios::binary. This is important, because the default text mode is "translated" in the sense that depending on the platform you run the code, the end-of-line character being issued in the file will be different ( on *nix, on mac, on Windows), even if you just use " " (without " ") in the code.

Hi Saldana We can use some thing from number theory so as periodic function or bijective function (one to one )function If unsigned char c = 0 to 255; int crypto = 5 just add to c+crypto =c, some one didn’t now the code he can’t read it By reversing c=c-crypto for every char in file you can read it; This very simple way; we can construct very complex file crypting by use word as whole number like abc=505153; than use some Number theory of division and prime number… We can use congruence c=b[a] ; a

Thanks Saldina, I was waiting for ages for this video. Actually I have a request to make, that if you find the time to do so, make an advance level video about file handling like about reading mixed data (numbers, alphabets, symbols, spaces, without new line) and taking out the specific type of data according to our desire and storing it in arrays, and also more info about functions like getline and putting some conditions in their parameters to ignore specific characters. Me and my friends will be waiting desperately. 🤞🏻🤞🏻
