Building Starknet Smart Contracts
In the previous section, we gave an introductory example of a smart contract written in Cairo, describing the basic blocks to build smart contracts on Starknet. In this section, we'll be taking a deeper look at all the components of a smart contract, step by step.
When we discussed interfaces, we specified the difference between the two types of public functions, i.e., external functions and view functions, and we mentioned how to interact with the storage of a contract.
此时，您应该会想到很多问题：
- How can I store more complex data types?
- How do I define internal/private functions?
- How can I emit events? How can I index them?
- Is there a way to reduce the boilerplate?
Luckily, we'll be answering all these questions in this chapter.
