cout您的编程风格涉及大量代码重复，这会导致错误。@AJNeufeld已经向您展示了如何混淆某些变量名。如果您的变量名中有数字，并且这些数字可能大于2，则很可能您应该使用数组。
另一个问题是，您有shopItemXName
，shopItemXDescription
等等，或者将许多商店商品的属性放在其他地方。最好将这些东西分组到一个结构中。然后您可以执行以下操作：
struct ShopItem {
    char *name;
    char *description;
    int price;
    bool bought;
};

const int nItems = 4;
struct ShopItem shopItems[nItems];

std::vector<item> database { 
    { "Heart Canister", "Increases your maximum health by 1.", 25 },
    { "Wooden Sword", "Increases your damage by 2.", 40 },
    /* ... */
    { "Toy Plane", "A toy plane. Does absolutely nothing.", 50 }
};

for (int i : chosen_items)
    display(database[i]);

稍后，您可以将大量重复代码重构为for循环，如下所示：
for (int i = 0; i < nItems; i++) {
    if (!shopItems[i].bought) {
        cout << i << ". " << shopItems[i].name << ":\n"
             << shopItems[i].description << "\n"
             << "$" << shopItems[i].price << "\n \n";
    }
}

for（int i=0；icout我的建议是从键盘后退一步。深呼吸。从1000到200倒数7秒
现在仔细想想你在这里做什么。这里有相当一部分代码实际上只是数据。如果你将数据表示为实际数据，那会更好（至少在我看来）
让我们从项目列表开始。每个项目似乎有三个元素：名称、说明和价格。因此，让我们定义一个结构：
struct item { 
    std::string name;
    std::string description;
    int price;
};

有了它，我们可以定义项目表，如下所示：
struct ShopItem {
    char *name;
    char *description;
    int price;
    bool bought;
};

const int nItems = 4;
struct ShopItem shopItems[nItems];

std::vector<item> database { 
    { "Heart Canister", "Increases your maximum health by 1.", 25 },
    { "Wooden Sword", "Increases your damage by 2.", 40 },
    /* ... */
    { "Toy Plane", "A toy plane. Does absolutely nothing.", 50 }
};

for (int i : chosen_items)
    display(database[i]);

由于我们的项目在一个向量中，我们可以按数字选择四个项目：
std::vector<size_t> chosen_items;

for (int i=0; i<16; i+= 4)
    chosen_items.push_back(rand_range(i, i+4));

这仍有待进一步改进，但我认为一般的方法可能会产生比代码前进方向更令人满意的结果。
听起来您可能需要学习如何使用调试器来逐步完成代码。有了一个好的调试器，您可以逐行执行程序，并查看它在哪里运行如果你要做任何编程，这是一个必不可少的工具。进一步的阅读：如果你张贴一个（最小的强调），可能有人会去调试你的代码。看起来像一个复制粘贴错误。考虑使用向量（甚至数组）。项和循环。您可以通过使用结构和容器简化代码。通过使用结构的std:：vector
可以消除许多函数。
