The Complete Solidity Course - Zero to Advanced for Blockchain and Smart Contracts - Exercise - Set Keys and Values

The video tutorial guides viewers through deploying a contract, creating addresses, and using a mapping contract to assign unique values to keys. It emphasizes the importance of ensuring each key has a unique value. After setting up, viewers are instructed to remove addresses and check their updated values. The tutorial concludes by encouraging viewers to practice these concepts independently.

What is the first step in working with the mapping contract?

• Deploy the contract

• Create keys as addresses

• Remove all addresses

• Check updated values

What should each key in the mapping contract have?

• A default value

• A unique value

• A shared value

• A null value

What should you do after setting keys to unique values?

• Remove all addresses

• Create more addresses

• Deploy another contract

• Set keys to default values

What is the final task mentioned in the video?

• Check for errors

• Create additional keys

• Experiment with mapping

• Deploy a new contract

What is the purpose of experimenting with mapping?

• To gain deeper understanding of mapping

• To understand contract deployment

• To practice setting default values

• To learn about address creation
