fried rice nutrition calculator

By: Yuna Wu

Have you tried to use program to make a calculator? This semester, we use programming to make a nutrition calculator. I will talk about what I did and what I learned during the time that I was doing the nutrition calculator.

Let me tell you how did I make this nutrition calculator. First, I use a class called “Ingredient” to write down the ingredient. Then I make a function called “calculateProteinCarb” to calculate the nutrition. This part is the part that included the most mathematical and calculation parts. After that, I use “let” to call the function, and I use “sum” function to add all ingredients. And then I make a printer function to print out the result.

I learn how to use “sum” function to add all ingredients, and I also learn how to call functions at one time through doing this work. I also learn about science through doing this work. I learn how many ingredients the food has, and I learn there has a special way to calculate ingredients. I also learn about math through doing this work. Do this work need to understand how to calculate the ingredients. I learn how to calculate the ingredients. I also learn how to turn math into programming. Actually, it took me a long time to understand the math and make it into a program. And it also took me a long time to understand the things that Dr.Bell told me. In math, my comprehension has always been poor and I often don't understand it, so it really takes me a lot of time. So every time I understand or make it, I will feel a sense of accomplishment and feel very happy.

Through doing this work, I know that I can do some programming by myself. I also know that sometime I should try to figure it out by myself more. But sometimes I really need people to help me because I am really easy to mess up by myself. When I have trouble with my program, I always get help from Dr.Bell. Every time I get help from Dr.Bell, he will ask me where I have trouble. I will tell him the place where I have trouble, and Dr.Bell always will help me to figure it out, and try to let me understand it.

I think in the future, I can use this skill to do maths easily, and quickly. I think in the future I can try to do this more, and be more careful with the spelling part. In the future programming is a really useful thing, I think everybody should learn some of it, so learn some programming together with me!

你有沒有試過用程式的方式來做一個計算機呢？在這個學期，我們用程式來做了一個計算營養成分的計算機。在這篇文章中，我會講到我在做這個計算機的期間所做的事情還有我所學到了東西。

請先讓我來告訴你我是怎麼製作這個計算機的。首先，我做了一個class叫做“Ingredient”來寫下成分。接下來，我做了一個叫做“calculateProteinCarb”的函數來計算營養成分。這個部分是有最多的數學和計算的部分。之後，我用“let”來呼叫函數，並且使用“sum”函數把所有的營養成分加在一起。然後，我做了一個“printer”函數來把結果印出來。

我學會了怎麼用“sum”函數來把所有的營養成分加在一起，我還在這次的功課中學會了怎麼一次性呼叫函數。通過這次的功課我還有學到有關於科學的知識。我了解到了食物的不同成分，還知道了要計算成分是有一種特別的計算公式的。通過這次的功課我還有學到關於數學的知識。做這項功課需要了解怎麼計算營養成分，所以我學會了怎麼樣去計算營養成分。我還學會了怎麼把數學變成程式。實際上，我花了蠻久的時間去理解數學然後把數學轉換成程式。而且我也花了蠻長的時間去理解Bell老師告訴我的事情。在數學這方面我的理解能力一直很差，經常不懂老師講的數學，所以真的會花我蠻多時間的。所以，每次我理解或者是我做出來的時候，我都會有一種成就感，會覺得很開心。

通過這項功課，我知道我可以靠著自己做一些程式。我也知道有的時候我應該自己嘗試去弄明白。但是我有的時候是真的需要別人的幫忙，因為我自己很容易搞砸。每次我的程序出問題的時候，我總是去找Bell老師幫忙。每次我從Bell老師那裡得到幫助的時候，他都會問我我的程序哪裡出錯了。我告訴他我遇到了困難的地方，Bell老師總是幫忙我解決我的問題，然後試圖去讓我理解它。

我覺得在未來，我可以用這個技能來讓我的數學做得更容易，更快。我覺得在未來我可以嘗試做更多這種東西，然後在拼寫方面可以加強一下，不要老是打錯字。在未來，程序是一個非常有用的技能，我覺得每個人都應該多多少少要學一點，所以一起來跟我學習程序吧！
