In js NaN is a number that not equal to 0, not less than and more than 0.🤷♂
there's no NaN in C++, apart from float NaNs i guess..

Yes Nan is number type but not integer
artemetra 🇺🇦
it's a float/double
Ludovic 'Archivist'
To be pedantic it is some form of IEEE754 floating point value

In js we don't have floating type but if I say isInteger(NaN) it return false🤷♂

well yeah, float isn't an integer either
Ludovic 'Archivist'
I don't actually remember if IEEE754 is mandated to represent floating point values in C++

>console.log(typeof NaN)
number
i find this funny, "not a number" is a number

Is Nan useful really in c++?

Well, you fuck up your math but don't pay for math exception interrupts. It is a trade-off

otherwise i have never used it anywhere

I told my friends that NaN doesn't make sense, but they said you're not good at math
Ludovic 'Archivist'

Okay, so, C++ may use a different approach to floating points values, IEEE754 is not mandated
Ludovic 'Archivist'
There is actually a numeric limits traits to check that

In math we only have Undefined not NaN, yes?

How can I write a program that takes 200 number and return the largest and smallest without array ?

NaN is useful I think, but IEEE doesn't say Nan is a number like JavaScript😊

How can I write a program that takes 200 number and return the largest and smallest without array ?
I think in c he can use linked list and in c++ he can use vector
Ludovic 'Archivist'

You are going too far, you do not need to store the numbers, it can be done in space complexity O(1) and time complexity O(N)

How can I write a program that takes 200 number and return the largest and smallest without array ?
I'd make 3 variables, num, max, min, initialize them to 0, then make a loop of 200 iterations.
In each iteration ask to enter a number, then check if num is greater than max and lower than min...

how to include openmp? i istalled lib into /opt/homebrew/opt/libomp and set this dir to compiler settings. but anyway linker throw error:
clang: error: linker command failed with exit code 1
what I'm doing wrong?

Sorry, what build system is that?
DaviChan
Looks strange to me to be honest. Also the < > dont make sense if you specify tman absolute and entire path anyways?
DaviChan
Doesnt look very portable also
DaviChan
Oh, this is the clang error? I though that was a build file. Have you tried using cmake?
I don't think including a single header will do

Turbo is outdated, it was even prohibited to discuss by the previous rules of this group :)
