Question 4.
Flowchart (Putting it all together)
To complete your project, you followed a series of planned steps. Before starting any project, it is useful to estimate the time and resources needed to complete the task (devices, camera, people required to do the work, and anything else you think is important). This will help you complete the task as planned in a timely manner. It is also useful for anyone else who wants to help you with the task.
Similarly, when you work with machines, it is necessary to make a detailed list of instructions for getting the work done through the machine. Therefore, programmers write down the detailed instructions systematically —this is called an ‘algorithm’. Fill in the empty spaces to indicate what you did in the project— this is the algorithm for your project.
