// Your output should look exactly like this (the blanks should be replaced with the correct values):
/*
# 5: x contains: __
# 6: x contains: __
#13: x is: 0 and y is: 99
#17: The address of the first element is ____________
#18: The address of the second element is ____________
#20: The first element in a[] is __ and the second element in a[] is __
#22: Now, x contains: 99 and y contains: 0
#23: Now, a[0] contains: 0 and a[1] contains: 99
