arr[4] causes array index out of bound error, results in undefined behaviour, in your case - Garbage values, which is whatever was left behind in the memory block. An array of size 4 has index 0, 1, 2 and 3 only.

Do you understand arrays? Your code gives out of index errors.

rest arr[3] =0 as it has been allocated a blank space for array but has not been assigned so default is 0.
