c++ initialization of struct with std::list included [duplicate]

Question

I have the following question.

Check the below block of code, it initializes my members of my structure correctly.

typedef struct
{
    int var00;
    int var01;
}struct_;

int main()
{


    struct_ my_struct;
    memset(&my_struct,'\0',sizeof(struct_));
    return 0;
}

My new structure now(see below), includes also an std::list. What I have to do now, to keep the memset command in the code?

typedef struct
{
    int var00;
    int var01;
    std::list<int> my_list
}struct_list_included;

int main()
{


    struct_list_included my_struct;
    memset(&my_struct,'\0',sizeof(struct_list_included));
    return 0;
}

Why not simply provide a constructor? Also, those typedefs are not needed in C++. — user2100815

If you are coming from a C background and are learning C++ I suggest you get yourself a good C++ book. Your code has a lot of C-ism's in it that are unnecessary as C++ has built in mechanics to do these things. — NathanOliver

std::list is not a POD type, so I don't think you can do this via memset().
