I have questions about how people buy and sell ERC20 tokens through token exchange after successful ICO.
The token owners list the tokens on exchange and thus user can start trading the coins and hence the price of tokens become master driven.
In order to list the token on exchange for trade, I think the token
owner must provide token address. What functions must be included in
the token contract?
Each exchange has different requirements. Most exchanges are not just satisfied with token address. They need a complete code, they need an audit report as well. because any vulnerable token hack causes exchanges to lose the trusts of users.

To solve this challange we have a standard of fungible tokens ( ERC-20). So there is a common method to transfer tokens. Any token implementing ERC-20 standard have the same functions for transfer of tokens. So it is easier for exchanges implementing ERC-20 tokens to support any other ERC-20 token, without worrying about other details.
