depends on your purpose

I want to do competetive programming

who is s(he)?

probably you should make research and find out what languages are used

nice virus btw. 28 bytes

no, it’s a file (lol!) with youtube link (loooool)

Would have been cooi if it was an actual virus in 28 bytes lmao.

Would have been cooi if it was an actual virus in 28 bytes lmao.

it will be very specific, as all tiny viruses, for one maximum two systems on a world, and C nor C++ can provide such level of compactness, usually <1K bytes COM or TSR viruses used some self packers similar to DEMOSCENE 64K/4K/1K, at least required a MASM, TASM, or NASM and Amiga or 68086 ALU and CPU tricks knowledge, to use some CPU, system BIOS and video BIOS extensively to make some screen effects (for such small viruses , there no way to use socket or even floppies)

Still waaaaay cooler then a youtube link ))

Anybody pls , suggest me which is the better platform to practice competitive programming??

How about codeshef , leetcode and all?

yep you can go for it....but Hackeearth is good for beginners for practice

Hi am new in this group

cause nobody knows how to utilize new CPUs instructions (except me of cause) other way than waiting new version of gcc, intel vtune or embracarero, demoscene is almost dead, btw

you can’t complete C

How can I convert std::wstring to std::string?

How can I convert std::wstring to std::string?

You are saying that I cannot convert std::wstring to std::string. In that case, How can I go about doing the task?

I think you can use something like sizeof(wchar_t)/sizeof(char) to get number of string elements for each element of wstring

I'm pretty sure that won't work because code expects a null terminated strings and you may have a null byte in the wchar_t

its not a big problem to handle

Agree you just cannot .c_str() anymore. Although not sure why would you convert.

I have this code to get the current working directory. I need to combine the CRW with some file name... But, the compiler is throwing me errors saying that I cannot do it using std::wstring. Is there any way to get it work?

Need raw data? Then you may just .data() wstring

google what is TCHAR and how to convert TCHAR buffer to string

I am so annoyed that I can't even do this.

Codeforces

because if val is absent find returns s.end()

What if the value we want to find is last value?

s.end() is not the last. this is like empty iterator

like nullptr
