When you declare an array of ints, does c++ provide default values for that array? If so, are those default values 0?

Never assume that it does.  This is something that is compiler specific and will also vary if you are using a static array allocated on the stack vs a dynamic array allocated on the heap.  Pretty much some compilers may initialize your arrays with default values of 0 based on the datatype and other compilers will not.  To make your program as compatible with as many compilers as possible you should always initialize the array yourself.
