C語言：結構和數組

Question

是否可以使現有結構成為一個數組？

struct violation v1={"AA1", "Defective_Brakes", 150};
struct violation v2={"AA2", "Disregarding_Traffic_Signs", 150};
struct violation v3={"AA3", "Driving_Under_the_Influence_of_Liquor", 2000};
struct violation v4={"AA4", "Driving_while_using_Mobile_Devices", 200};
struct violation v5={"AA5", "Drinving_without_License", 750};
struct violation v6={"AA6", "Driving_Against_Traffic", 2000};
struct violation v7={"AA7", "Failure_to_use_Seatbelt", 500};
struct violation v8={"AA8", "Illegal_Parking", 200};
struct violation v9={"AA9", "Overspeeding", 1200};
struct violation v10={"AA10", "Reckless_Driving", 750};

這應該是我的代碼的數據庫。 我想把它變成一個數組，使數據庫中的搜索更容易。 我能做什么？

Answer 1

數組是同源的，即它只能保存一次，就像數組中的所有元素都是整數或字符串一樣，但你不能混合你可以使用結構的類型，我在你的例子中看到你有String和Integer，因此如果你想將你的結構更改為數組，然后你必須將它們全部轉換為字符串。

另外考慮你的情況，我會建議你繼續使用結構，因為它混合了數據類型。 您還可以使用struct violation violations [n];將所有這些struct存儲在數組中struct violation violations [n]; 然后使用for循環來填充違規行為，請按照如何在C中創建結構數組？ 完整的例子。

Answer 2

是。 就像您對常規數組所做的那樣，您可以創建一個struct數組：

struct violation v[10]={
                    {"AA1",  "Defective_Brakes",                      150},
                    {"AA2",  "Disregarding_Traffic_Signs",            150},
                    {"AA3",  "Driving_Under_the_Influence_of_Liquor", 2000},
                    {"AA4",  "Driving_while_using_Mobile_Devices",    200},
                    {"AA5",  "Drinving_without_License",              750},
                    {"AA6",  "Driving_Against_Traffic",               2000},
                    {"AA7",  "Failure_to_use_Seatbelt",               500},
                    {"AA8",  "Illegal_Parking",                       200},
                    {"AA9",  "Overspeeding",                          1200},
                    {"AA10", "Reckless_Driving",                      750},
                 };

Answer 3

您可以輕松地將數據放入數組中，而不是十個單獨的變量：

struct violation violations[] = {
    {"AA1", "Defective_Brakes", 150},
    {"AA2", "Disregarding_Traffic_Signs", 150},
    {"AA3", "Driving_Under_the_Influence_of_Liquor", 2000},
    {"AA4", "Driving_while_using_Mobile_Devices", 200},
    {"AA5", "Drinving_without_License", 750},
    {"AA6", "Driving_Against_Traffic", 2000},
    {"AA7", "Failure_to_use_Seatbelt", 500},
    {"AA8", "Illegal_Parking", 200},
    {"AA9", "Overspeeding", 1200},
    {"AA10", "Reckless_Driving", 750}
};
