C oder C++

[Artchi]

C++ Rocks! Das hat doch nichts mit C++ zu tun, sondern (wie du selber schon richtig festgestellt hast) liegt es am Compiler - sprich am Tool.
Der MSVC spuckt z.B. ganz andere Fehlermeldungen aus. Die vorallem meiner Erfahrung nach viel verständlicher sind. Weiterhin spuckt der MSVC z.B. zusätzlich Error-Codes aus (die der gcc nicht hat). Somit kann man den Error-Code in die MSDN eingeben, und dort stehen sehr ausführliche Beschreibungen und sogar Lösungsvorschläge zu den Errors!

Wenn ich einen BASIC-Compiler benutze, der schreckliche und missverständliche Fehlermeldungen ausgibt, hilft es mir absolut nichts, wenn BASIC eine gute Anfängersprache ist. Der BASIC-Compiler ist dann halt Mist.

Entschuldige Artchi, du hast natürlich Recht. Die Meldungen des Visual Studio Compilers sind sogar noch aussagekräftiger

23 errors? sieht irgendwie nach viel mehr aus.

Was natürlich nichts am grundsätzlichen Problem ändert - der Fehler sollte im Anwendercode auftauchen und nicht in irgendeinem Template in der Standardbibliothek. Dafür bräuchte man Concepts - aber daraus wird ja nichts. Mit erweiterten Fehlerinformationen wird es immerhin ein wenig besser:

Spätestens beim zweiten Error-Code weiß man, das da was nicht zusammen passt. Dann schaut man in die Std-Lib-Doku, und weiß das list eine eigene Sort-Funktion bereitstellt.

Den Fehler begeht denke ich mal jeder Std-Lib-Anwender in seiner Anfangszeit. Den Fehler hatte ich damals auch gemacht, std::sort() mit list anwenden zu wollen. Nach einem Blick in der Doku habe ich das nach ein paar Sekunden korrigiert bekommen. Vorausgesetzt man weiß das es unterschiedliche Iterator-Kategorien gibt. Das sind aber C++-Basics!

[mukuh]

wenn das basics sind, möchte ich ja nicht wissen mit was für fehlermeldungen sich der fortgeschrittene C++ programmierer so herumschlagen muß^^

28 KB Fehlermeldung auf diesem Platz könnte man in Forth ein Betriebssystem programmieren, inkl. Compiler ... alternativ *n*x fahren, die PDP 11/20 hatte 1971 ungefähr so viel Speicher im Vollausbau

Aber nur so am rande. Warum ist cout so viel umständlicher als printf? Ich merke nur das es durch die vielen "<<" hässlicher ist

C

printf("(%8.2f,%8.2f)\n", x, y);

C++

std::cout << "(" << std::setprecision(2) << std::setiosflags(std::ios::fixed) 
		  << std::setw(8) << x << "," << std::setw(8) << y << ")" << endl;

Also ich finde den C++ Code weitaus intuitiver und übersichtlicher!

Ist doch interessant dass der kurze formatstring "(%8.2f,%8.2f)\n" ganze zwei Zeilen c++ code ersetzt.

Das nenne ich mal minimalen Aufwand: Man braucht nur:
cout, setprecision, setiosflags, ios::fixed, setw und 674594 '<<'s und schon hat man den format string ersetzt.

Diese Diskussion printf vs cout erinnert mich an folgendes Beispiel: Wegbeschreibung.

C: Mit printf bekommt man die Wegbeschreibung in Form einer Karte, auf der man auf einen Blick alles überblicken kann.

C++: Hier wird der weg manuell beschrieben ala "gehe gerade aus << drehe dich nach links << schau dich um ob kein Gegenverkehr kommt << fahre dann 40 meter << im Kreisverkehr die zweite raus [...]"

Also cout muss wohl ein wahren Pragmatiker entworfen haben.

[volkard]

Ist aber total irrelevant. Willst Du süße Formatierung, nimmst Du eh Klickibunti.
Genauso die Länge mancher Fehlermeldungen. Die fallen in der Praxis gar nicht auf.

weils sie sowieso keiner liest. angeblich gibt's sogar tools, die fehler eines C++ compilers in menschenlesbare form übersetzen können (in eine zeile oder so).

Du hast Recht, meistens reicht es, die erste Fehlermeldung zu lesen.

Und oft reicht es, nur die Fehlerzeile zu wissen.
Bei den Monstern kommt in meinem Hirn nur "Templatefehler" an und dann schaue ich, was im Code an dieser Zeile einen Templatefehler macht.

[Don06]

Im neuen Standard gibt es doch static_assert. Könnte man dann die Fehlermeldung nicht wesentlich besser gestalten. Z.B.:

Incompatible iterator types. Expected: random access; Used: bidirectional

Vielleicht ists ja sogar im Visual C++ 2010 schon eingebaut (static_assert wird ja unterstützt).

[sdfsfsd]

Ohne Python und C++ gegenüberstellen zu wollen, aber die python exceptions sind deutlich aussagekräftiger. Okay, ich muss eingestehen, die exceptions sind auch runtime-Meldungen.

Aber prinzipiell hat C++Rocks recht mit seinem Sarkasmus.

Ich hab schon öfters gehört, daß die meisten C++ Programmierer die Fehlermeldungen des Compilers nicht verstehen und quasi solange am Code rumpantschen, bis er dann irgendwann kompiliert
