/*
# print all the sub-arrays from an integer array inputed by the user
steps:
-> take array size input & array element inputs
-> pass the array to a function 
-> the function will use 2 nested for loop
-> the outer for loop will control the starting index
-> the inner for loop will control the ending index
-> using the indexes, a built in function will print out sub-arrays
