The 0 thing for octal, i ran into that in production code once and it took me at least 30 minutes to figure it out. What happened was that to align various #defines in source code so that they look pretty, someone put a bunch of zeros in front of the numbers so everything lines up in the code and starts at the same column. The code was misbehaving in a weird way. After staring at the code for 20 minutes and finding seemingly nothing wrong with it, I fired up the debugger, went through the various actions to get to the code in question (this took 10 minutes) and only in a debugger after loading the value and seeing the wrong value in memory, by seeing what the value loaded was, I immediately realized it must be interpreting it as octal. I will never forget this! Hex is 0x, Binary is 0b, why not 0o for Octal? I love C++ (I know this is C) but having a plain zero mean octal is just insane...

Such a valuable knowledge sir I didn't know that before truly speaking

[shreyeah-tf]

0:53 0 before integer is treated as an octal value

[JackVaileon]

Well, the real quality education is here. I really appreciate you all. Thanks a lot from Myanmar❤️

[shwetakadgi]

Love you Neso Academy ❤

Edit : I hope you know how much easy you are making an engineering student's life !!! Thanks a million !!!!

[ishpreetsingh]

Woh. That’s something I don’t know before. Great logic.

[Kim-rhgt]

nice video and lesson, has increased my understanding of C language

2:34 Why is there no need of #Include <stdio.h>?

[lxathu]

I think when 52 octal is written with %o, it's not fortunate to pronounce the displayed 52 as fifty-two. It's misleading, especially for the beginners. That number has nothing to do with the number we know as the sum of five times ten plus two times one.
It's just "five-two (octal)".

Best part of the videos is the explanation 💖💖for all the answers which arent provided by other channels; ❤❤

[sandeeppadamatinti]

Which one is better neso or code with Harry.
A) neso
B) code with Harry

[deepakbhardwaj]

Question series is the best parts ever sir and thanku

[max.caimits]

I thought it would be a compile error, for printf won't be found. But it's just a warning without #include <stdio.h>

[soranarapiteanu]

You're doing a great job explaining this stuff! ^^

[MohankumarV-cbrv]

what is the output for this c program?

#include<stdio.h>
#define STRING "%s \n"
#define NESO "Welcome to Neso academy"
int main()
{
printf(" Welcome to Neso Academy! " STRING, NESO ) ;
return 0;
}

neso academy.. thanks.. these questions were very tricky indeed

[UTTAMKUMAR-gtfj]

I would like to say thank you so much to nesho academy .
I could not understand in my college during first year when i found this channel then i have been started learning c language and after watching all videos i have become as like master of c so once again thank u so much sir jee love u to all faculties of nesho academy

[compangit]

Comment for myself: putting 0 in front of an integer variable translates that number into an octal value. This is true if the variable is to be printed as a decimal. If it's "%o", and the value is an octal, then it prints normally.

[niveshduppalapudi]

Awesome I m now totally interested in the subject

[shubhamaggarwal]

please suggest a book from where we can practice quetion and test our knowledge.
