All those books are outdated now and many of the topics and practices covered in those books don't apply to Modern C++. Scott Meyers' Effective Modern C++ is a good book though

int c, nl;
nl=0;
while((c = getchar()) != EOF)
if (c =='\n');
++nl;
printf("%d\n", nl);
if I write something and press enter, then ctrl+z it always returns 1, even if I put more newlines. why?

How to split strings when inputs have something like “Jam\\\0n” the representation of the string result is ‘J’, ‘a’, ‘m’, ‘\\’, ‘\0’, ‘\n’,
?

The thing is we have to use type casting

i wonder why do people still using non standard stuff when new learning C/C++
shriman_deepak
dx.ID = atoi(line.substr(0,3).c_str());
dx.Author = line.substr(4,16);
dx.Title = line.substr(20,38);
dx.Publisher = line.substr(41,50);
dx.Year = atoi(line.substr(54,58).c_str());
dx.isbn = line.substr(57,75);
here what is the purpose of digits in the bracket after substr ?

conio.h and getch is non Standard
conio.h has inputs in offline compiler windows so when compiling online have to remove it right and cant remove getch

But it's NOT STANDARD. There's no guarantee it can run on other platform. Why not getchar() instead ?

I think no, because it's implementation are different
\Device\NUL
I think no, because it's implementation are different
Try
in Windows/DOS
#include <conio.h>
getch()
The program will wait the user input.
But in Linux
#include <ncurses.h>
getch()
I didn't input anything but the program is end`
Roger
did conio.h in bits/stdc++.h (?
\Device\NUL
No

Including <bits/stdc++.h> directly is also bad habit.

use stoi()

In C
sizeof('a') == sizeof(int)
In C++ are not
sizeof('a)' return char size
Prince Of Persia
In C++ are not
sizeof('a)' return char size
👍
C++ does it like that
But C doesn't
Actually idk why C returns int size

Probably Gentoo, as, from the start, you compile your entire system, so not only all the tools and libs will be there by the time you finish, but you'll understand a lot more about them.

I don't recommend source based distro unless you have specific reason like optimization, building stuff, etc.
There's also Clear Linux that made by Intel and of course it's optimized for Intel CPU because -O3 and -march -mtune

I use Kernel 4.14 in android with Termux or Kernel 5.16 in arch Linux. (Or in most cases, it doesn't matter unless you have a particular hardware and want to utilise maximum of it. For example, If I am concerned about battery life and I have a Zen 2+ processor, I will stick with Kernel 5.17+)
