In this example, the constructor takes one per duration. When the contract is deployed, duration is set as the initial value of the state variable duration. It's important to note that the constructors are code only once and cannot be code again after the contract is deployed. This makes them perfect place to put any setup or initialization logic for your contract. Let's say you want to set another state variable owner of the contract at the time of the deployment. Let's say how we can do it. First of all, we can define a owner state variable, which is address, and then within the constructor, let's assign the sender of the…
