Accounting and finance are somewhat related yet quite different. Accounting has (GAAP) General Accepted Accounting Principles) and corporations have to follow those to do their revenue, expense, cash accounting. Finance deals with numbers but can go into personal financial planning, corporate strategic plans where you do forecast and budgets but you are not as regulated on how you are reporting the numbers .
I was an accounting major, and I feel if you do that you can still have a finance understanding at the Corporate Level. However if you want to go and work for Investment banks, then finance would be a specialized subject that a lot of folks take when they specialize at the Master's level or do their MBA.
