Better way to initialize struct bools?

Deftwun (28)
So say I have a struct:

1
2
3
4
5
 
struct MyStruct{
    bool Member1,
         Member2,
         Member3;
};


The way I normally would initialize these is by using a constructor with an initializer. ie:

1
2
3
4
5
 
MyStruct::MyStruct():
    Member1(false),
    Member2(false),
    Member3(false)
    {}


However when I have a fairly large struct that I don't really know yet what it will consist of this can lead to some potential headaches if i forget to initialize a member.

Can I initialize these when they're declared or do something cool like:
1
2
 
MyStruct mStruct;
mStruct = false;


Thanks!

If your compiler supports new features of C++ then you can write

1
2
3
4
5
 
struct MyStruct{
    bool Member1 = false,
         Member2 = false,
         Member3 = false;
};


As for this record

1
2
 
MyStruct mStruct;
mStruct = false;


it is invalid.

Sweet thanks that is what I was looking for.

I knew that was invalid as far as that example but I was just hoping there was some super obscure technique to make it work.

Thanks again!

struct my_struct
{
    bool a ;
    bool b ;
    bool c ;

    my_struct( bool f = true ) : a(f), b(f), c(f) {}
};

my_struct one = true ; // true, true, true
my_struct two = false ; // false, false, false

When I read "fairly large struct" I think near 100 member variables. If this is the case you really just have to bite the bullet and write the code correctly.
