Does Zcash AUTOMATICALLY Hide All Transaction?

When I send Zcash from one address to another, is it automatically hidden or is there something I have to do to ensure that it is hidden from public ledger.

Where can I view the public ledger for Zcash or other coins?

Thanks!

No, you need to use a z-address for transactions to be private. There are 2 types of accounts: z-addresses and t-addresses. T-addresses are "transparent" and you can lookup account balances at https://explorer.zcha.in/.
