We’ve got it all now! You are now ready to fully solve Muffin’s third task. And not just solve it, but make the program more user-friendly and intuitive. Let us remind you about the task:
Third task: “Write a program for calculating the caloric value of my breakfast. I have milk for breakfast. I want to enter the amount of milk I drank and see its caloric value.”
Let’s break the solution down into several steps:
- collect breakfast data from Muffin,
- save this data to a variable for further processing,
- show a message that the data has been received, so that Muffin is no longer worried,
- process data using mathematical operations where we use our first variable,
- save the result of our calculations to a second variable,
- and show a message with the result of our program’s work.
Let’s first deal with the first three steps and cover the other three in the next task.
Working together: we come up with variable names, texts, and formulas, you write the code.

Let us remind you about the task:</p><p><b>Third task</b>: “Write a program for calculating the caloric value of my breakfast. I have milk for breakfast. I want to enter the amount of milk I drank and see its caloric value.”</p><p>Let’s break the solution down into several steps:</p><ol><li>collect breakfast data from Muffin,</li><li>save this data to a variable for further processing,</li><li>show a message that the data has been received, so that Muffin is no longer worried,</li><li>process data using mathematical operations where we use our first variable,</li><li>save the result of our calculations to a second variable,</li><li>and show a message with the result of our program’s work.</li></ol><p>Let’s first deal with the first three steps and cover the other three in the next task.</p><p>Working together: we come up with variable names, texts, and formulas, you write the code.</p></div></div><div class="js--theory-pane__comments hidden course-theory__content-inner"><div class="course-theory__content-text"><h2 class="course-theory__content-heading">Comments</h2><div id="disqus_thread"></div><script>
