Initializing an arrays of integers

Code:

---

int a[10] = { 0 };

---

This will initialized all elements of a to zero on MS Visual C++ and Dev-C++ 4.9.9.2. I'd like to know if this is part of the C++ standard or if it's compiler dependent. If possible, could you guys provide me a link where I can read about it? Thanks.

When you use an initializer list for an array, if you specify fewer values than the array size, the rest of the array will be initialized with 0. Try this:

Code:

---

int a[10]={100};
cout<<a[9]<<endl;

---

I think it must be part of the standard, but I couldn't say for sure.

See:

It's standard - all remaining initialisers are set to 0, '\0', 0.0 or NULL (as befits the type of thing being initialised).
