和
int arr1[] = {1,2,3,4,5};

是arr1在堆栈上还是在堆上声明?
我想知道如何在 python 中使用与模板 < typename T>类似的代码,因为它在 C++ 代码示例中使用:
template <typename T>
unsigned int counting_bit(unsigned int v){
v = v - ((v >> 1) & (T)~(T)0/3); // temp
v = (v & (T)~(T)0/15*3) + ((v >> 2) & (T)~(T)0/15*3); // temp
v = (v + (v >> 4)) & (T)~(T)0/255*15; // temp
return v;
}

我将如何在 python 中以与 C++ 中提到的相同的方式使用变量 typename 类型转换对象?
我正在使用Microsoft bot框架创建一个机器人来询问用户然后理解答案.在bot框架中使用FormFlow API对用户进行询问并检索答案.以下是表单流的代码:
public enum Genders { none, Male, Female, Other};
[Serializable]
public class RegisterPatientForm
{
[Prompt("What is the patient`s name?")]
public string person_name;
[Prompt("What is the patients gender? {||}")]
public Genders gender;
[Prompt("What is the patients phone number?")]
[Pattern(@"(<Undefined control sequence>\d)?\s*\d{3}(-|\s*)\d{4}")]
public string phone_number;
[Prompt("What is the patients Date of birth?")]
public DateTime DOB;
[Prompt("What is the patients CNIC number?")]
public string cnic;
public static IForm<RegisterPatientForm> BuildForm()
{
OnCompletionAsyncDelegate<RegisterPatientForm> processHotelsSearch = async (context, state) =>
