Write a program to take input from user in Fahrenheit and convert it in Celsius and print it.
Celsius=(F-32)*5/9

How can I define a const variable in a class
For example: pi = 3.14 , how can I define it?

For example: pi = 3.14 , how can I define it?
Just like that: const double pi = 3.14;

why not just use const, just like comment above hehe

The question was not having a static object there. Was it?

well there isn't much use in having a non-static constant member variable

Don't ask meta questions. In other words, don't ask to ask. Questions like "Does anyone know XYZ?", "Has anyone used XYZ?" or "Can someone help me?" are all considered meta questions because they don't specify what your actual problem is.
These questions give the impression that you want people to approach you and offer their help as if they don't have any other work to do. Now doesn't that expectation make you look like an idiot?
If you have a question ask it directly. You are more likely to get a response that way.

I need help in cmake and I try to ask in every channel but No one help. I use boost from git, And I use it in cmake with FetchContent_Declare. But it's not in include dir's and is empty, How I can fix that ? or how I can make CMake install it ?

is there any reason not using vcpkg?
or perhaps using cpm-cmake?
AmR
I don't know it, And I don't like it.
Suka
How I can setup it and install boost ?
sudo pacman -S boost-libs
or
vcpkg install boost
or if using xmake
xrepo install boost

(i < 95)
?(do something)
:(do something);
i = (i < 95)
?(do something)
:(do something);
why do both of these codes run the same way? i mean whats the difference...
lets say i have to use the value of i while doing that 'do something'...so i don't want its value to be changed..but in the second part it looks as if i am assigning a value of 0 or 1 to i based on the condition (i<95)

The only difference is that in the first case you evaluate the expression and discard the result, and in the second case you evaluate the expression and assign the result to i

The value of i will depend on which branch executed: the "？" or the ":"
Pavel
The assignment to i happens after the evaluation, so doing it doesn't affect the results of the evaluation
Aaryan

okay, so i is assigned after either ? or : branch is executed?
Pavel
okay, so i is assigned after either ? or : branch is executed?
Yes, everything on the right side of the = should be executed before the result can be assigned (to i in this case).
You can check the order here
https://en.cppreference.com/w/cpp/language/operator_precedence
(I guess it is worth noting that the list explains the order of evaluation of operators, but not operands of those operators, more about the later here:
https://en.cppreference.com/w/cpp/language/eval_order)
Abbasi

It depends on the result of the condition. If it's true the first value will be assigned to i, the second value otherwise.

What is cprintf( );
In c language
Reported Damo [831217613] to admins.
Amit
cprintf is a non-standard C function that writes formatted output directly to the console. It is similar to printf, but it is specifically designed for console output.
Amit
I think you need to add conio.h which is obsolete
Amit
printf is the alternative
