there may be students who are studying computer science in university. and i am asking why most universities teach c++ than java. Because i am following most curriculums of universities and they only plan to teach c++

This highly depends on the university. At my University Java is the primary language being used.
Although we had to use wide range of languages such as c++, c, Ada, Haskell, Scala, maybe VHDL and Prolog
The choice of the language can depend either on industrial demands or research projects.

Store pi value in a variable, please
Mat
Arrays start at 0 here
Mat
Have you done a Ctrl+c,Ctrl+v here?
Anulekh
Yeah
Mat
Write your own code, don't do that
Mat
And try to understand what's going on for every step
Anulekh
I didn't copy the code from outside source...what i copied is part of the code of my program from one place to other
Anulekh
Sorry to bother you guys... I just sorted it out...inside the loop i misstyped y[i] instead of y[j].....
Anulekh
Thanks for the response
Mat
Oh, didn't notice
Mat
Try to clean a bit all that mess
Mat
clean as make it clearer
Anulekh
How to replace value of pi?
Rajinikanth
You can use #define header file
Mat
Try to initialize variables
Mat
int something {};
THAT'S CPP
Mat
You avoid undefined behaviour this way
BinaryByter
const double pi {3.14...};
THAT'S CPP
Theres a stdlib function that gives you the best amount of precision depending on tte type of fpoint you ask it for, iirc
BinaryByter
But this is just a wild guess
Mat

Yep, i know. But i don't remember the lib
Mat
int something {};
THAT'S CPP
That's like
int something = 0;
but better afaik
And
int a {3};
is equivalent to
int a = 3;
but better
THAT'S CPP
BinaryByter
BinaryByter
You can see it like passing the int as a constructor to int
BinaryByter
Its not better, its different
olli
BTW c++ does not define PI as a constant
BinaryByter
You should use {} instead of () for class instantation so as to avoid MVP
BinaryByter
:P
olli
There was a proposal for C++20 to add several math constants though
Mat
Fuck!
Mat
He was using C
BinaryByter
There was a proposal for C++20 to add several math constants though
Which would result in some crazy shit
BinaryByter
Idk
BinaryByter
Sensible
olli
Depends on the language of course. I think adding M_PI as preprocessor macro to math.h and cmath would probably be sufficient for most cases
BinaryByter
Well maybe it isnt that outlandish

There were stuff like plank constant, pi, gravitational constant etc etc
BinaryByter
There were stuff like plank constant, pi, gravitational constant etc etc
Who needs the plank constant lmao?
BinaryByter
I dont put my dick's size into my programs
BinaryByter
I feel like i scared him with my inane shitpostisg

That's like
int something = 0;

And
int a {3};
is equivalent to
int a = 3;
but better

When using braces your compiler warns you about narrowing conversions
BinaryByter
What are narrowing conversions?
olli
int i = 3.9;
BinaryByter
Like. Float to int?
Mat
Yes
Mat
It says that you're doing something not wrong but not good
BinaryByter
Imho the braces are ugly
Ludovic 'Archivist'
When using braces your compiler warns you about narrowing conversions
It always does when narrowing as for me, which is normal
BinaryByter
You dudes use clang. Eww
Ludovic 'Archivist'
Like, when doing
int a = some_long_int;
olli
"warn" in terms of error
BinaryByter
You should enable the warnings=error tag
Ludovic 'Archivist'
A narrowing issue is an error
olli
Although the standard does not prohibit this behavior.
olli
In contrast, using brace-initializers the standard does
Ludovic 'Archivist'
Although the standard does not prohibit this behavior.
It does not in respect to C standard
Ludovic 'Archivist'
In contrast, using brace-initializers the standard does
Which is why it does in that case
olli
But I don't care whether it's in respect to C or something else, it is still technically allowed
(http://eel.is/c++draft/conv#fpint-1)
Ludovic 'Archivist'
olli
exactly, so why not use {} which prohibits this behavior?
BinaryByter
Because its ugly, redundant, and unclear of intent
BinaryByter
The more i look into modern cpp the more i recognize php in it
BinaryByter
Whicd asaddens me
Ludovic 'Archivist'
exactly, so why not use {} which prohibits this behavior?
I prefer using {} as for me, it is a good habit to get to avoid mvp issues
BinaryByter
I prefer using {} as for me, it is a good habit to get to avoid mvp issues
Should i use it aswell?
