Comment by Peter - Reinstate Monica on c syntax help - very basic
The historical context is that C originally was a very weakly typed language. (For example, there were no function prototypes!) The language also acknowledged that addresses -- i.e., pointers! -- are...

Additionally, even old versions of web sites (including software repos) are often copied/cached/archived in multiple places, systematically and spontaneously. It is basically impossible to remove...

Make sure you haven't mixed up the contents of main.h and main.c in the copying process. "object specified more than once", I suppose, means that your solution contains more than one definition of an...
View ArticleComment by Peter - Reinstate Monica on '\0' evaluates false, "\0" evaluates true
Note that while "\0" compares unequal to 0, *"\0" compares equal (since it is a char of value zero). (By the way, the reason you never see a string literal dereferenced except in this comment, even...

@PeteBecker Incidentally, it is actually the division and multiplication causing the problem here, plus the conversion to double, paradoxically. Only adding and subtracting in two's complement would...

Apparently, you have used VS Code with some success before (you say you elaborately configured many of the extensions which seems to indicate you were using it). Is that correct?
View ArticleComment by Peter - Reinstate Monica on Why does dos2unix print to stderr?
@MarkLakata As an aside, that is probably not exactly the dos2unix function, namely for data that contains standalone carriage returns (for whatever reason). dos2unix should only affect CR-NL pairs.

I suppose your existing project is a project producing an executable? Then you have two choices: (1) Create an entirely new project in your second solution which produces a library from the same files...

You can delete your source code from the question, it is a distraction (or replace it with a "Hello World!"). Your problem is in the setup.You have two main ways to go about this: Use a fresh (possibly...

In POSIX environments (i.e., basically, -nixes and posix compatibility layers on top of Windows, notably cygwin and msys), there is an "assignment-allocation character 'm'" which instructs scanf to...

@Caner-sagopaninsagkolu OK, that's a link error. The code sees the declarations, the compiler produces the proper calls, but the linker cannot resolve them. You need to add the libraries or .c files...

s and r must be defined as true arrays, not just as pointers. And when passing them to scanf, don't take their addresses; they are converted to pointers automatically.

@Gene I don't know boost.pfr either, but it appears to me that if I create a specialization for, say, 10 elements I kinda know how many I have, don't I? ;-) Also, iterating can simply be done...

As mentioned in the comments (thanks to matt, phd), this is possible with GitLab but not with github. The OP understandably but wrongly expected feature parity :).

@PasserBy is a bit mean. Of course: The C standard library is part of C++, which makes calls to gmtime() and localtime() perfectly valid C++; it's just not the preferred way, by some. Simply mention...

I think Ian's remark goes a long way, and is prudent advice anyway: If all asserts are your own you can make sure to scrub the sensitive information before asserting. Admittedly, that will complicate...

In particular, short of reflection there is no way to avoid (wordy and error-prone) repetition of names for producing strings from identifiers, except using the preprocessor.
