The Complete Solidity Course - Zero to Advanced for Blockchain and Smart Contracts - Scope and State in Solidity

The video tutorial explains the concept of public functions in smart contracts, focusing on how they provide access both internally and externally. It discusses modifying data within functions, the implications of such changes, and the need to adjust function properties like 'view'. The tutorial also covers the process of compiling and deploying contracts, observing state changes, and understanding how these changes affect outputs. Through practical examples, it demonstrates redeploying contracts and the resulting state updates.

What does it mean when a function is declared as public in a smart contract?

How can you change the data output internally in function X to 17?

Why can you not view the result of function X after removing the view?

What happens to the state variable when you run function X after setting it to 17?

What will be the output of the data variable after running function Y?
