Daten werden nicht gespeichert, um angezeigt zu werden?

Question

Ich bin ein Anfänger, der eine Programmierklasse nimmt und ich habe Probleme mit meiner Aufgabe. Ich soll ein Programm erstellen, das Daten speichern und sortieren kann (ich habe Spiele gewählt), und alles scheint in Ordnung zu sein. AUSSER wenn ich ein Spiel eingeben und später die von mir eingegebenen Spiele anzeigen möchte, wird nichts in der Liste sein. Gibt es etwas, das mir fehlt?

Answer 1

Sie vergessen, Wert in Ihrem Array zu setzen.

i hinzufügen 4 Zeilen getGames funktionieren:

array->Title = Title; 
array->Date = Date; 
array->Developer = Developer; 
k++; 

und eine Zeile in der Funktion displayGames ändern:

for (int i=0; i < k; i++) 

dieser letzte Code ist:

// test_3.cpp : Defines the entry point for the console application. 
// 

#include "stdafx.h"
