Ich bin ein wenig neugierig, warum das Programm, das ich auf Xcode mit einem Mac schrieb fein läuft, aber wenn ich versuche, auf einem Windows-System mit Visual Studio kompilieren,Fehler C3861 in Visual mit std :: transformieren
Ich erhalte folgende Fehler:
c:\users\bryan\documents\visual studio 2010\projects\new\new\new.cpp(172): error C3861: 'transform': identifier not found.
als ich im Programm umwandeln überall schreiben, in der Tat, sagt es die gleiche Botschaft, wie transformieren, wenn nicht ein Teil des std-Namespace ist. Hier ist mein Code, wenn Sie für sich selbst sehen möchten:
#include <iostream>

string capitalize (string choice);

Das Problem der unter dem funciton Kapital zu verwandeln ist. Es scheint überhaupt nicht zu transformieren, ich habe sogar versucht, std:: davor zu schreiben, aber es hieß, dass es kein Element namens transform gibt. Gibt es ein Problem mit meinem Compiler, oder wird die Transformation sogar noch verwendet, seit ich das neue Studio heruntergeladen habe, oder ist es vielleicht nur eine schlechte Übung?
