How do you initialize an array?

If you want to initialize an array, try using Array Initializer: int[] data = {10,20,30,40,50,60,71,80,90,91}; // or int[] data; data = new int[] {10,20,30,40,50,60,71,80,90,91}; Notice the difference between the two declarations. When assigning a new array to a declared variable, new must be used.

Why is return array equivalent to return array [ 0 ]?

Then return array is essentially equivalent to return &array [0]. The problem is that, since the array is allocated in the function’s stack frame, it ceases to exist when the function returns, thus the caller gets a pointer to an area of memory that is not allocated anymore. Likely memory corruption ahead.
