Calling a struct constructor in a class constructor body

[Karl M]

Hi C++ experts!

Definitely I skipped C/C++ 101 because I have this pitfall:

I need to call the struct ctor in the class default ctor body see below:

//Some.h

struct MyStruct

{

int a[5];

below:

Add an explicitly defined default constructor to your struct that does the
initialization:

//Some.h

struct MyStruct

{
int a[5];
MyStruct()
{
std::fill(a,a+sizeof(a),0);
}
};

{

MyStruct()
{ std::fill(a,a+5,0);
}
};

std::fill(a,a+5,0);

Yeah, that'd be better ;-) Or maybe even :

std::fill(a,a+sizeof(a)/sizeof(a[0]),0);

Thank you guys,
