Give example of adjusting journal entries

Basic adjusting entries are an entire chapter long, and that's just the basics.

How about some reading material instead:
Principles of Accounting (http://www.principlesofaccounting.com/chapter3/chapter3.html#Adjusting)

An expample would be for depreciation. You first have to calculate the amount of depreciation for the period, then the journal entry will be: Debit Depreciation Expense for the amount and Credit Accumulated Depreciation for the amount.
