初始化程序错误无效 [英] invalid initialiser error

问题描述

错误是在int [4] = ItemID，t;

我正在尝试使用ItemID对我的文本文件stockdatabase.txt中的项目进行排序，以降序排序。 br $>

the error is on int a[4] = ItemID,t;
I am trying to sort the items from my text file "stockdatabase.txt" using ItemID to sort in descending order.

void Transaction::SortDescending()
{
    getStockTotal();

    system("clear");
    sort(ItemID);
    cout<< ("stockdatabase.txt");
    cout << logo_Descending << endl;
    Myfile.open("stockdatabase.txt");

    void sort(int &ItemID);
    {
        int a[4] = ItemID,t;
        for (int e=0; e<4; e++)
        {
            for (int r =3; r>=e; r--)
            {
                if (a[e]<a[r])
                {
                    >
                    t = a[r];
                    a [r] = a [e];
                    a[e] = t;
                }
            }
        }
    }
}

推荐答案

Of当然这条线完全无效。对我来说，很难想象这行可能意味着什么，这与C ++语法无关。一个问题是你甚至没有显示 ItemID 和 t 的声明。



例如，这里解释了数组的初始化： http：//www.cplusplus .com / doc / tutorial / arrays / [ ^ ]。

Of course this line is totally invalid. To me, it's hard to even imagine what could you possibly mean by this line, which has nothing to do with C++ syntax. And one problem is that you did not even show the declarations for ItemID and t.

Initialization of arrays is explained, for example, here: http://www.cplusplus.com/doc/tutorial/arrays/[^].
