Question

在正确评分此问题时遇到问题。它一直显示为100％中的87％，但所有先决条件都按预期运行。该程序应该采用一些cookie并确定要使用多少个cookie，盒子和容器，并在有一个时输出剩余的cookie。显然，我错过了一些东西，但我无法弄清楚是什么。

一盒24个饼干。

容器中有75个盒子。

非常感谢任何帮助。

#include <iostream>

    // Write your main here

    int cookies;
    int leftoverCookies;

    int leftoverBoxes;

Answer 1

不应该这一行

else if (boxes < 75) {
    containers = 0;
    leftoverBoxes = 0;

改为阅读...

else if (boxes < 75) {
    containers = 0;
    leftoverBoxes = boxes;

？，由于没有足够的盒子可以添加到容器中，左侧的盒子应该只是盒子的总数

Answer 2

您可能会忽略此练习的重点 - 您不需要一个条件，只有/和%。

顺便说一句，摆脱条件也可以在boxes < 75时修复错误，并设置leftoverBoxes = 0而不是leftoverBoxes = boxes。

你只需要这样的东西：

int main()
{
    int cookies = 0;
    cout << "Please enter the total number of cookies: ";
    cin >> cookies;

    int boxes = cookies / 24;
    int leftoverCookies = cookies % 24;

    int containers = boxes / 75;
    int leftoverBoxes = boxes % 75;

    cout << endl
         << "The number of boxes used: " << boxes;
    cout << endl
         << "The number of leftover cookies is: " << leftoverCookies;
    cout << endl
         << "The number of containers used: " << containers;
    cout << endl
         << "The number of leftover boxes: " << leftoverBoxes;
}

现在代码问题给出了预期的输出
