如何使程序确定最大的用户输入

Question

所以我的任务是编写一个程序来确定公司四个部门中哪个部门在一个季度的销售额最高。我基本上对我的 cout 语句没有吐出位置有疑问。这是我所拥有的： 函数原型：

double getSales(string const);
void findHighest(double, double, double, double);

main(不能碰教官命令)：

//variables
    double nwSales, neSales, swSales, seSales, highest; 
    string const NW = "Northwest",
                 NE = "Northeast",
                 SW = "Southwest", 
                 SE = "Southeast"; 

    cout << fixed << showpoint << setprecision(2);

    nwSales = getSales(NW); // these are calls to a function that returns a value
    neSales = getSales(NE);
    swSales = getSales(SW);
    seSales = getSales(SE); 
    findHighest(nwSales,neSales,swSales,seSales); 

函数定义：

double getSales(string const location)
{
    double sales;
    cout << "The " << location <<" branch had a quarterly sales figure of: $ ";
    cin >> sales;
    cout << "\n";
    while (sales < 0)
{
        cout << over3 << sales << " is not valid! Try again: "; 
        cin >> sales;
}
    return sales;
}

我很确定这是对的。我主要是在这部分遇到问题：

void findHighest(double nwSales, double neSales, double swSales, double seSales)
{
system("CLS");
double highest  = nwSales;
string const location = "Northwest";

if (neSales > highest)
{
    highest = neSales;
    location = "Northeast";
}
if (swSales > highest)
{
    highest = swSales;
    location = "Soutwest";
}
if (seSales > highest)
{
    highest = seSales;
    location = "Southeast";
}
cout << down5;
cout << "The highest grossing division was " << location << "with $ " << highest;
cout << down7;

}

我不明白为什么它不告诉我位置。我尝试将 cout 语句放在每个 if 语句 bu 中，这完全搞砸了一切。希望有人能够指导我正确的方向。

试试这个

string location = "Northwest";

      no const
