我发现编译错误。其实很管用。但我把这个代码提交给了网站进行分配。一个网站警告我，您有一个问题，说“不匹配'operator='（操作数类型是'product'和'')”我该如何解决这个错误呢？我应该在哪里修复代码？

#include <iostream>
using namespace std;

struct Product {
    char name[3][6];
    int price[3];
};

int main() {

    Product A, B, C;
    char ch;
    int sum = 0;
    int average;
    
    A = { "strawberry", "melon", "watermelon", 300, 500, 1000 };
    B = { "strawberry", "melon", "watermelon", 450, 450, 900 };
    C = { "strawberry", "melon", "watermelon", 200, 150, 700 };

    cin >> ch;

    if (ch == 'A') {
        for (int i = 0; i < 3; i++) {
            sum += A.price[i];
        }
    }
    else if (ch == 'B') {
        for (int i = 0; i < 3; i++) {
            sum += B.price[i];
        }
    }
    else {
        for (int i = 0; i < 3; i++) {
            sum += C.price[i];
        }
    }

    average = sum / 3;

    cout << average;

    return 0;
}
