Default initialization in C++

Question

I was asking myself something this morning, and I can\'t find the words to properly \"google\" for it:

Lets say I have:

struct Foo
{
  int bar;
};

s         


        

Answer 1

Case 3 is the proper way, with a member initialization list.

None of the first two will be properly initialized, since you don't give them an initial value (exactly like a variable only defined is not initialized).
