Auto-array is a normal array which we commonly use in C++ or any other language.
it is basically initialize on stack. it is initialize as usual in following way:
int intNum[] = {10,20,90};
it is not same as static array.
A static array is array which is initialized only once i.e.
 void func()
{
        static int intNum[] = {10,20,90};   //line-1
       // other code   //line-2
     //
}
when i call this function for the first time ,only at that time only line-1 will
get executed and for rest of the the function will execute from line-2 onwards.
What it mean is that when ever i am revisiting this function it will retain the last stored value of intNum array, will not destroy this lastly stored value by executing line-1
