product black_breath = { "black bread", 21, "21.12.2022", "21.12.2022", 24, 34, 43 };

for (int i = 0; i < 20; ++i) {
std::cout << product[i].name;
}
return 0;

}

Надо вывести все элементы name из структур

Answer 2 · 2023-04-07 12:16:48

Проблема возникает потому, что в вашем коде попытка обращения к элементам структур `product` происходит как к массиву, а не как к полям каждой структуры. Поправьте ваш код таким образом:

```
for (int i = 0; i < 20; ++i) {
std::cout << products[i].name << std::endl;
}
```

Таким образом, вы можете обратиться к полю `name` каждой структуры `product` из массива `products` в цикле. А кроме того, стоит заметить, что в вашем коде вы обращаетесь к несуществующему типу данных `products`, в то время как название переменной - `white_bread`, `wheat_bread` и т.д. Если вам нужно использовать массив структур, то объявите массив и добавьте в него все структуры:

```
product products[] = {
{ "White bread", 1, "21.12.2022", "21.12.2022", 11, 100, 18 },
{ "wheat bread", 3, "21.12.2022", "21.12.2022", 9, 70, 118 },
{ ... },
...
};

for (int i = 0; i < 20; ++i) {
std::cout << products[i].name << std::endl;
}
```
