Defines an array of 30 integer elements, giving an even number starting from 2 in order, and then averaging each of the five numbers in order, placing them in another array and outputting them.

Assign arr Arr[i-1] because the array subscript starts at 0

Make a judgment of the five numbers as a group and then put the average of each group into another array
