c++ Error C4996 VisualStudioComunity15

Question

Well, i have tried to combine 2 things in one, ive got some errors and solve them,but now im stuck... i cant compile the code because of this error...

Those 2 things are 2 previous questions that i had on this site:
1) https://www.sololearn.com/Discuss/794515/how-can-you-output-something-as-a-superscript-and-subscript-in-c >>helped by Babak Sheykhan
2) https://www.sololearn.com/Discuss/815290/c-printing-the-correct-number-of-decimal-points-with-cout >>helped by Kinshuk Vasisht

I have been reading about it in several places:
https://stackoverflow.com/questions/19079482/error-c4996-std-copy-impl-function-call-with-parameters-that-may-be-unsafe
https://stackoverflow.com/questions/38060411/visual-studio-2015-wont-suppress-error-c4996

Ive tried those ideas and couldnt figure it out what am i doing wrong, at some point i was getting more errors then the first place, so i belive i should let the code where i belive im doing smth wrong.

IDE Visual Studio Community 2015
Here is the code with the issues: https://code.sololearn.com/c6b7m100D9Jv/#cpp

Any solutions, ideas, or advice to change something(or to try different)...are welcome as always :)

Answer 1

Error C4996:
Severity Code Description Project File Line
Error C4996 'std::_Copy_impl': Function call with parameters that may be unsafe - this call relies on the caller to check that the passed values are correct. To disable this warning, use -D_SCL_SECURE_NO_WARNINGS. See documentation on how to use Visual C++ 'Checked Iterators' ConsoleApplication14 c:\program files (x86)\microsoft visual studio 14.0\vc\include\xutility 2230

I have no idea what it is :D ive tried to go in xutility(line 2230):
template<class _InIt,
class _OutIt> inline
_OutIt copy(_InIt _First, _InIt _Last,
_OutIt _Dest)
{ // copy [_First, _Last) to [_Dest, ...)
_DEBUG_RANGE_PTR(_First, _Last, _Dest);
return (_Copy_impl(_Unchecked(_First), _Unchecked(_Last),
_Dest, _Is_checked(_Dest))); //line 2230
}

This is just over my head :)))

Probably i will try to find another IDE-compiler and try with what you had :) even if it will be only for my knowledge.(i am tring to make a bigger project,maybe is going to help my CV). I want to get in the programming area :) even as an intern or smth, unpaid whatever, im still waiting for a call to an internship interview :) Dont judge, im just hoping...and if i get it soon it will be really big deal for me :( sry for the crying.

Thank you for the responses!
Have a great day!

edit: i dont "give" you the mark as correct for a little bit :) i mean you check it and it works, but maybe i found the issue with this IDE that i use(is pretty good for me i belive,shows a lot of problems). I will wait a few days maybe and give the mark. :)

Answer 2

@derXred, I've used gcc on Linux and it worked. Probably the problem is related to some library differences. Not that my answer solves anything, I just posted it in hope it somehow helps to track the issue.
Also, can you post a full error message here, maybe it will give some insight on what's wrong. And one thing you can try to localize the source of the problem - try commenting out chunks of code, and see if it compiles. Start of commenting out whole contents of the Print() function. Then uncomment parts of it and try to build.

@~ swim ~ And my gcc didn't complain about a thing, even with -Wall...

Answer 3

I don't have Windows available to test this, but this code kind of works on Linux. The only issues were:
- Line 22 #include "stdafx.h" should be commented
- Line 145 wfout.open(L"Stats.txt"); should be changed to wfout.open("Stats.txt");
- Line 122 delete[] dno_char; results in segfault, so I commented it out too

I'm really too lazy right now to figure out what the code does, but it outputs a file with the following contents:
writable 1.002 dno_char s_convers
2 0.0004 4 1113 60.0010 1 4 320.5002 12 113 60.0010 1 1113 60.0010 writable 0.3 dno_char s_convers
1113 60.0010Line 1: Hello²!
Line 2: O³ x₀ + x₁ + x₂
Line 3: x₃₊₄
Line 4: € Euro!
Line 5: 2⁷⁻⁹

And if I change Line 160: std::cout << std::endl; to wfout << std::endl; , the outputs get a bit better IMO (in my text editor it looks more aligned than with this font):
writable 1.002 dno_char s_convers
2 0.0004
4 1113 60.0010
1 4 320.5002
12 113 60.0010
1 1113 60.0010
writable 0.3 dno_char s_convers
1113 60.0010
Line 1: Hello²!
Line 2: O³ x₀ + x₁ + x₂
Line 3: x₃₊₄
Line 4: € Euro!
Line 5: 2⁷⁻⁹

Answer 4

@Vincent Blankfield [LMGTFY]

Yes the output is messy, because i wanted to see some values(im not so pro :D) and i wanted to combine the 2 codes and then make it nice for the eye..I dont know if is a good practice, but this is how i learn faster and understand more things.

"Line 22 #include "stdafx.h" should be commented" -- that is a file auto-made when i create the project(PROBABLY here is the problem, but i could do other projects...i really dont know)
"And if I change Line 160: std::cout << std::endl; to wfout << std::endl; " -- ive just miss that :)

Ive tried all you said ,but is the same error...

Probably is because of the IDE...are you using the same thing? Maybe i should try it on a different IDE...(maybe im saying something stupid).

Thank you for the response! :)
