However you can write it in decimal using %d in printf easily
András
You have to cast it to int previously
Benedetto Califfo
I think u re right

I haven't programmed using c for years ahah

just subtract by 0x30 to get int¯\_(ツ)_/¯

one question guys, say I need to take input in my program,
数学の恋人
but I know that input is restricted say it's only allowed to give input as integers from 1 to 100
数学の恋人
is it possible to optimize performance here?
数学の恋人
like instead of doing usual way
int n;
std::cin >> n;
Ariana
The most i can think is
read a character
subtract 0x30
check if its 0-9
if it isnt break, else loop
Billy

Did you already mesure that input is your performance bottleneck?

Hi. Is there any simple way to access a protected or a private member of a class for debugging purposes? Or do I have to modify the class in order to peek into an object's internal state?

Debuggers such as lldb are able to inspect private members, not sure what you consider "debugging purpose"

But it's not possible to do with just language itself? So far the simplest solution I found was to comment out access specifiers and just put public: at the start of the class.

How do you debug your code? After compilation there are no access modifiers anymore

Oh, by simply outputting various variables during runtime.

That's not the best way to debug your code. You could create a public method that dumps all the fields.

Is it? Doesn't the comma operator guarantee the order of evaluation?

Or it can evaluate in random order and return just the last one?

The order or evaluation of function parameters is not defined, e.g. clang has a different one than gcc.

Well, comma operator is not a function technically..

a function call does not invoke the comma operator though
olli
A function call is a postfix expression followed by parentheses containing a possibly empty, comma-separated list [...] [expr.call]

Of course, in a function call it is just a separator

Look at line 14, there's no function call

x++ is executed (x is 11), then ++x is executed and assigned to y, so x and y are 12
How the variable y got the value 12
pratheep
(There are 2 values inside the bracket)

How only one value is returned

Did you not have basic database setup and configuration so far?
Or is the task to create your own?
András
Even vscode is better than visual studio
Oleksandr
lol vscode sucks vs visual studio
Oleksandr
I’m both vs code and VS user, and vscode only good for editing file or two. If you have more - you’ll end up with spending more time fixing configs for intelisense than actually working
Oleksandr
mac users says same about xcode

I was working with visual studio, and I hate that experience. It was time, when ide refuse to open the file, becouse it's is already open, but it's close
András
It's time when I need to save my code every 5 seconds, becouse I don't know when ide will crash
András
It's time when my compiler suddenly forgot where is all my libraries
Oleksandr
Really sorry to hear that. I was lucky enough to not experience crashes more that once a week, so I have a very positive experience, comparing to vs code and xcode(its sucks that macs does not have c++ support in mac VS)

I want to ask what the (probably assignment) is about. Do you have to write your own basic database or are you asking how to setup a way with a pre-existing database to store the data?
