使用std :: array vs array传递对象数组

Question

今天我和我的朋友讨论了在C ++中传递对象数组的正确方法。这两者之间是否存在效率差异：

class myform(FlaskForm):
connection = removed
result = connection.execute("SELECT * FROM sqltable")
result = result.fetchall()

scenarioList = []
fieldList = []
fieldLabel = []

for scen in result:
scenarioList.append("Scenario: " + scen[0])
fieldList.append("field: " + scen[0])

for i in range(len(result)):
fieldLabel.append("My Field" + str(i + 1))

myDynamicFields = dict(zip(fieldLabel, fieldList))
formID = StringField('Form ID')

for key, val in myDynamicFields.items():
exec(key + '=StringField(val)')

Struct Apple {
    std::string color;
}

void colors(Apple A[]) {
    A[0].color = "red";
}

int main() {
    Appple apples[10];
    colors(apples);
    return 0;
}
