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.

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++?

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 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++.

can anybody explain me purpose of auto keyword in c++? thanks
It's useless and is left for old code compatibility. Long ago you used it to say that a variable is automatic, this is no longer useful - all variables witout other qualifiers are treated as automatic (stack-allocated).
