constructor - Is there a way to make a C++ struct value-initialize all POD member variables?

Question

Suppose I have a C++ struct that has both POD and non-POD member variables:

struct Struct {
    std::string String;
    int Int;
};

and in order for my program to produce reproduceable behavior I want to have all member variables initialized at construction. I can use an initializer list for that:

 Struct::Struct() : Int() {}

the problem is as soon as I need to change my struct and add a new POD member variable(say bool Bool) I risk forgetting to add it to the initializer list. Then the new member variable will not be value-initialized during struct construction.

Also I can't use the memset() trick:

Struct::Struct()
{
   memset( this, 0, sizeof( *this ) ); //can break non-POD member variables
}

because calling memset() to overwrite already constructed non-POD member variables can break those.

Is there a way to enforce value-initialization of all POD member variables without explicitly adding their initialization in this case?

I am not sure whether something like that is possible [directly] or not but the following works

prasoon@prasoon-desktop ~ $ cat check.cpp && clang++ check.cpp && ./a.out
#include <iostream>
struct Struct {
    std::string String;
    int Int;
    bool k;
    // add add add
};

struct InStruct:Struct
{
   InStruct():Struct(){}
};

int main()
{
   InStruct i;
   std::cout<< i.k << "  " << i.Int << std::endl; 
}
