c++ - C++ -和“访问冲突写入位置 0x86A1ECD8”

Question

我正在尝试为我的学校项目制作一个百货商店项目。我为产品创建了一个类数组，以包括它们的名称、价格、库存和所购商品的数量。但由于某种原因，我收到一个错误弹出窗口
“Test project.exe 中的 0x68665139 (vcruntime140d.dll) 抛出异常：0xC0000005：访问冲突写入位置 0x86A1ECD8。”

另外，执行后我收到一个错误，称为错误读取字符串字符。

这是我的代码：

#include<iostream>
#include<string>


using namespace  std;

class product {
 private:
    int stock;       //items in stock
    int add_stock;   //added stock
    int purchased;   //purchased items(reduces stock)
    string name;     //name of item
    float price;    //price of item

    public:

//fuctions to input all private variables
void setstock(int x) {
    stock = x;
}
void setaddstock(int x) {
    add_stock = x;
}
void setpurchased(int x) {
    purchased = x;
}
void setname(string x) {
    name = x;
}
void setprice(float x) {
    price = x;
}

//functions to output all private variables
int getstock() {
    return stock;
}
int getaddstock() {
    return add_stock;
}
int getpurchased() {
    return purchased;
}
string getname() {
    return name;
}
float getprice() {
    return price;
}

//function that restocks the items
void restock() {
    stock += purchased;
}

//function that deducts purchased items from stock
void destock() {
    if (stock >= purchased) {
        stock -= purchased;
    }
    else {                                                              //in case the purchase demand exceeds items in stock
        cout << "\nSorry we only have " << stock << "amount of left\n";
    }
}
};




int main() {
int purchased;
product stuff[10];              //class array
int choice, total_qty = 0;      //choice-> to choose between products, 
total_qty-> total number of products purchased
char yesno;                     //to choose if user wants to buy anything 
else (for do loop)
float total_price = 0;          //total amount of money to be paid 


// declaring product name and price 

 stuff[1].setname  ("Coconut biscuits");

// declairing the number of items in stock and setting purchased = 0 for easy calculation  
for (int i = 1; i <= 10; i++) {
    stuff[i].setstock     (100);
    stuff[i].setpurchased (0);

// displays the menu, make purchase, repeat

cout << "\ntotal price: " << total_price;



return 0;

Answer 1

for (int i = 1; i <= 10; i++)

应该

for (int i = 0; i < 10; i++)
