//This is real life smart contract function which contains tasks array of struct
//taskToOwner container to map taskId with msg.sender.and AddTask event.
//We all use function in addTask function
contract TaskContract{
   //COMMENT EVENTS
    event AddTask(address recipient,uint taskId);

    //COMMENT Task structure
     struct Task{
         uint id;
         string taskText;
         bool isDeleted;
     }
     
     //COMMENT create array name tasks with struct Task
     Task[] private tasks; 

     //COMMENT mapping in taskToOwner with key value pair of taskid with owner address
     mapping(uint256 => address) taskToOwner;
     //COMMENT Contract function
     function addTask(string memory taskText, bool isDeleted) external {
        uint taskId = tasks.length;
        tasks.push(Task(taskId,taskText,isDeleted));
        taskToOwner[taskId]=msg.sender;
        emit AddTask(msg.sender,taskId);
     }
