Unicode Processing in C++

Closed 5 years ago.
I have to write a C++ program to specify a character from input if it is a number or word or symbol? Firstly I used ASCII to solve that, but the problem is when the input is not a character in ASCII, example it is in UTF-16, it is a Korean word...
So what can I do to solve?
Thank you!
wchar_t should be the one you are looking for.
In C++, wchar_t is a distinct fundamental type (and thus it is not defined in nor any other header).

I recently came across the following C++ code snippet:
int Mod = 998'244'353;
I was intrigued by the use of single quotes in this number.
Could someone elaborate on what this gets interpreted as and why is it accepted?
Also has this formatting always been there in c++?

Many languages allow you to insert underscores into long hex numbers to improve readability. I would like to put underscores into hex numbers that define forty bit hardware addresses. For example I would like to write 0x0400000000 as 0x04_0000_0000.
It is tough for me to count consecutive zeros but I can handle groups of four.
Does C or C++ allow punctuation inside hex constants?
Is there a practical workaround if something like this is not allowed in the language?
Thanks,

What does the caret (‘^’) mean in C++/CLI?

Closed 7 years ago.
I read an article about C++ language. There is lines using "^", not XOR.
Sample code is like:
array<String^>^args = System::Environment::GetCommandLineArgs();
The symbol ^ is used for managed pointers.
Read http://msdn.microsoft.com/en-us/library/cxx6f46y.aspx , for more information about them.
They are from C++/CLI though and not C++.

Dump facility in C++ like var_dump() in PHP?
I'm not sure does C++ even allow this kind of thing, but I was wondering, could it be possible to write a generic function that could output any type array (std::vector) as plain text, as long as I write myself each of the types output function, for example std::string, float, int, etc.
So, how could I go through the structs types and output them one by one by different output functions made by me?
You should have a look at cxx-prettyprint. http://louisdx.github.com/cxx-prettyprint/
I think it does all your asking for.

What is %n in printf?
How to use it in my codes (with a sample code please)?
Thanks.
Edit:
After googling I couldn't found any sample about %n. But some people close this question without an answer.
The %n specifier does not print anything and the corresponding argument must be a pointer to signed integer where the number of characters written so far is stored.
