c++ - 查找用户输入值的总和

Question

我需要帮助使用 C++ 将多个用户输入的值相加

double total;     // Accumulates total
double price;      // Gets next price from user
int numItems;     // Number of items
int counter = 1;  // Loop control counter

cout << "How many items do you have? ";
cin >> numItems;
cout << endl;

while (counter <= numItems) {
    total = 0;
    cout << "Enter the price of item " << counter << ": ";
    cin >> price;
    cout << endl;
    total += price;
    counter++;
}
cout << "The total price is: " << total << endl;

当我运行我的代码时，我最终只从用户那里得到一个值的总和

是的，正如 Chetan Ranpariya 所说:

total = 0; 应该在 while 循环之前。
