C++ 如何求和正积的负因子

我可能没有在标题中很好地解释这一点，因为我真的不知道如何解释标题的长度，所以我对此表示歉意。无论如何，这是我当前的代码：

// Gets the product that is used to get the factors
cout << "Enter a number that you want to be factored" << endl;
cin >> y;

system("cls");

// Gets the sum from the user that the two factors need to add up to
cout << "Input the sum that is needed" << endl;
cin >> neededSum;

secondary = y;
system("cls");

// Lists the factors that add up to the specified sum
cout << "The numbers that add up to " << neededSum << " are:" << endl;
for (int i = 0; i < 100; i++)
{
    x++;
    increment++;
    y = secondary / x;
    product = x * y;
    if (product == secondary)
    {
        sum = x + y;
        if (sum == neededSum)
        {
            cout << x << " and " << y << endl;
        }
    }
}

//获取用于获取因子的产品
库蒂；
系统（“cls”）；
//从用户处获取两个因子的总和
不需要总和；
次级=y；
系统（“cls”）；
//列出加起来等于指定总和的因子
不能假设x和y为负：

if (product == secondary)
{
    sum = x + y;
    if (sum == neededSum)
    {
        cout << x << " and " << y << endl;
    }
    else if (-sum == neededSum)
    {
        cout << -x << " and " << -y << endl;
    }
}

if（产品==次级）
{
总和=x+y；
如果（总和==需要总和）
{
一开始就把它们都写出来怎么样？那么所有的底片和帖子呢？
