Thread: Global variables question(very simple)

Are global variables automatically declared as static and initialized to 0? What ANSI says about this?

Thanks for any answer!

>Are global variables automatically declared as static and initialized to 0?
If by global variable you mean this:

Code:

int a; // Global

int main()
{
    ...
}

Then yes, the standard guarantees that a will have static linkage and be initialized to 0.
