Even if you disagree, it's not going to change anytime soon

I don't think any respectable company would not hire you for not knowing nitty gritty details of a language

Reading and understanding some legacy code of your project. Job interviews
Why do people look at C/C++ and jump to legacy projects?
Sid Sun
Additionally it's good to know that int array[100]; is not the same as int array[100] = {};
I can see using this, it'd be nice to have some predictable default values

Because they're wannabe legends

I'm gonna be writing a program to automate systemd service creation coming weekend in C++, this week I'm rewriting my CD solution (implemented in python to finalize everything) to Go

Interesting

10mins later i finally realized that array is on the stack 😂

What is CD solution?
Continuous Deployment, it works like this:
You develop locally
Deploy to your GitHub
GitHub sends a message to an API which is configured to run a script which compiles and deploys the latest version of your program

So automatic deployment? But isn’t that bad if you are testing your code?

Or updating it?

It is configurable like:
You can configure it to use only the deployment branch
And
You can also make it not automatically deploy but deploy when it gets a request from you to start deployment
Sid Sun
And since I'm making it as a pair of APIs, you can also build a web app, a program, a mobile app which plugs into it and allows you to:
See history of deployment
See logs
What are the changes since last deployment
Deploy it
etc

Because C++ is pretty old (not as COBOL of course but still not as golang), there are lots of legacy projects already. Maybe they have been rewritten tens of times, but still have a lot of old code in them.
There are also still old-school programmers that write code like 20 years ago and don't like these modern std::array and std::vector, so there's a chance to see such code in a new project

Yes, of course there are legacy projects in C++

But i think it's become a stereotype, which it should not be

Listen use %f at the place of %d then u will easily enter decimal value from user
Not my code. No idea what he was trying to do

hi! Can somebody tell how to use lambda in if statements?
Bojan_Krdemn
if (lambda) {}

create an array and initialize with 0
int array[100] = {};
Good one, I hate it when people use {0} here
Anonymous
It needs calling ...
And what will the value of those "initialised elements" which have not been initialised by the programmer?
— — —
#include <iostream>
int main (){
char der [8] = {'a','s','g'};
std::cout << der [5];
return 0;
}
— — —
I mean 4 and 5th element?
Anonymous
undefined
And what does Unmentioned array elements are value initialized mean?
Is undefined related to value initialised?

It's a different case. Not yours

no, it's 0 as stated per 6.7.9.21 in N1570
Anonymous
@MasterZiv So, the value is 0 (as per him) or again undefined.

Read what value initialization means

Unmentioned means well... not mentioned

Why don't you write
char der [8] = {'a','s','g', 0};
or
char der [8] = "asg";
?
Artöm
and what about other cases?
Man read it https://en.cppreference.com/w/cpp/language/value_initialization
