我是一名参加编程课程的初学者，我的作业遇到了麻烦。我要创建一个可以存储和排序数据的程序（我选择了游戏），一切似乎都没问题。除了当我选择输入游戏，然后显示我输入的游戏时，列表中没有任何内容。我有什么遗失的吗？

};
void getGames(VidyaGames array[], int &k);
void displayGames(VidyaGames array[], int &k);
void deleteGames(VidyaGames array[], int &k);
void sortGames(VidyaGames array[], int &k);
const int MAX = 150;

}
void sortGames(VidyaGames array[], int &k)

答案 0 :(得分：1)
你忘了在数组中设置值。
我为函数getGames添加了4行：
array->Title = Title;
array->Date = Date;
array->Developer = Developer;
k++;
并在函数displayGames中更改一行：
for (int i=0; i < k; i++)
这是最终代码：
// test_3.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <cstdlib>
#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
#include <sstream>

string Title;
