@BjörnSundin Ah, of course. Actually, c++20 does it.

Reading the standard may not be the best or at least not the easiest way to learn a language. It covers a lot of edge cases that make a very simple language look complicated. Part of the reason is that...

Typical terminals send the input even in standard mode when enter is pressed; none of this should be necessary unless you are behind a pipe.

I think this is not what the OP asked for. Their main issue is that the program simply does not see any input after a regular (i.e., non-enter, non-break etc.) key press since the terminal is in line...
View ArticleComment by Peter - Reinstate Monica on Why int **m its not equal to int m[][]?
It is probably confusing to the OP because it is the exception to the C rule that declaration mimics usage, caused by the (repeated!) type conversion from array to pointer.

@Chris The question is entirely clear and certainly does not need debugging details. It is also not exactly the question linked in your comment: Sure, the issue underlying the confusion is array...

A JIT compiler can optimize based on run-time information which result in stricter border conditions which were not provable at compile time. Examples:It can see that a memory location is not aliased...

Are you using or creating those libraries? Also, if you are using automake you should say that clearly, also as a tag. I'd use cmake if I could.

Why so dismissive? Tired? Frustrating work day? ;-) The constraint is in the CMake logic as far as it is known to me (files can only be added to a target which is logically wrong). The various IDEs in...

@WeatherVane Re "check size first": Interesting idea; fseek() (the standard way) may be pretty fast and likely pays for large files. In principle though, proper byte-by-byte comparison takes care of...

Even GC.Collect(2, GCCollectionMode.Forced, true, true); GC.WaitForPendingFinalizers(); did not reclaim objects defined in Main whose references had been nulled. Surprising. (dotnetfiddle.net/5laO72)

I am not exactly sure why that is; I would have assumed that the gc collects the objects. A modified version of your test has the same results, see dotnetfiddle.net/5teY0S. People always point out how...

View ArticleComment by Peter - Reinstate Monica on Use scanf() to read \n in a loop?
There is no guarantee that the input is line buffered. It may come from a file, or the terminal settings may have changed.
View ArticleComment by Peter - Reinstate Monica on Use scanf() to read \n in a loop?
If you need line-by-line processing, use fgets() and parse the read line with sscanf() (if that counts).
