47 | - To write your code, click on the project (i.e. **questionXXX**), open **src** directory and click **Main.py**. This will open this file in the editor and you will see the code provided to you. You must write your code to this file between the comments (i.e. # DO_NOT_EDIT_ANYTHING_ABOVE_THIS_LINE and # DO_NOT_EDIT_ANYTHING_BELOW_THIS_LINE). You are **NOT ALLOWED TO MODIFY** these comments or anything outside the region marked by the comments. If you delete/modify these statements, you can restore them from **Main.py.txt**
48 |
49 | 
50 |
51 | - After you write your solution, please make sure that
52 |
53 | - You write your solution to **Main.py** (Not Main.py.txt)
54 | - You do not modify/delete the statements already given to to you. *You can compare these statements with the ones in Main.py.txt*
55 | - You do not use any import's.
56 | - The input and output of your code are exactly same with the input/outputs in the description. (*You don't have unnecessary input or print statements*)

6 |
7 | This video explains how to **configure your default Python Interpreter**. You must only do this once, and the default interpreter will be determined for all projects you create, and all Quizzes you take. **If you don't perform this before your Quiz**, your code may be interpreted by a different version of Python in your computer, and **you may not get a full grade**. Please make sure that you set your default Python interpreter as Python 3.8.6 (location may differ in different systems, refer to the *Create a new project* section in the [Installation Guide](Installation%20Guide.pdf).
8 |
9 | 2. Teaching.Codes Login (https://youtu.be/AQX5aZXDSz8)
10 |
11 | You must **make sure that you can login** to your Teaching.Codes accounts before the Quiz.

18 |
19 | Please watch the solutions to the **problems encountered during the Quiz**, so that you may take some precautions beforehand.
20 |
21 | At the end of the video, we show you how to open question description if you can't see it via Teaching Codes. The solution in the video can sometimes give inconsistent results. So here is the updated solution:
22 |
23 | 1. Right click on the html file
24 | 2. Choose "**Show in Explorer/Finder**". This step open the folder that contains the html file.
25 | 3. From the folder, open the html file.

48 |
49 | If you're using MacOS, please download the .zip file using **Chrome instead of Safari** to avoid any issues.
50 |
51 | 2. Open PyCharm.
52 |
53 | 3. Inside PyCharm, for Windows, click ***File-->Settings***; for MacOS, click ***PyCharm-->Preferences*** and find ***Plugins*** on the left.
54 |
55 | 4. Go into ***Plugins***, and select the ***Teaching Codes JB*** plugin. From the right, click **the arrow next to the *Disable* button**, and select ***Uninstall***. Select ***Yes*** if it asks for confirmation.
56 |
57 | 
58 |
59 | 5. **When the uninstallation is complete, click OK, and then** **close PyCharm**.

11 | ## Announcements
12 |
13 | - We will use **PyCharm** and **Teaching Codes** plug-in in projects and exams. Student accounts will be created for this plug-in.
14 |
15 | - The username and password will be sent to **the e-mail in BUIS** **after add drop period**. We will make an announcement when the credentials are sent.
16 |
17 | - If your email address that you use in BUIS (registration.boun.edu.tr) is anything other than
18 |
19 | - **@gmail**
20 | - **@boun.edu.tr**
21 |
22 | Please change it to @gmail.com, or @boun.edu.tr. In order to do that,
23 |
24 | - Go to https://registration.boun.edu.tr, and Login.
25 | - Enter General Settings, and then E-Mail Management.
26 | - You should change your current Contact E-mail Address to @boun.edu.tr or @gmail.com.
27 |
28 | - Please check announcements on Moodle **regularly**!
29 |
30 | - Lab hours are dedicated to **practical programming exercises not for covering lecture materials**. I **strongly** suggest you to attend the lectures.
31 |
32 | - Follow the Installation Guide and TeachingCodes Guide to complete installation and get familiar with the environment.
33 |
34 | - The installation must be completed **until April 9, 2021**. After that date, questions regarding installation **WILL NOT BE ANSWERED.**
35 |
36 | - What counts as **cheating**:
37 | - **Information exchange between students:** Giving and Receiving information to/from your colleagues both count as cheating.
38 | - **Using codes from any source other than the materials of our course:** You can consult internet or books to learn and improve your programming skills. But you shouldn't use any material that is not your own work in the projects and exams.
39 |
40 | - Check **FAQ** and **Technical Support** to get help.

73 | 74 | ## Question 7 75 | 76 | There is a cash machine with an infinite supply of 5tl banknotes and 1tl coins inside it. 77 | 78 | Write a program that takes an integer as input representing the amount of money requested by a customer. The program then prints the number of banknotes and coins given to the customer. (Machine must prefer giving away banknotes instead of coins if possible) 79 | 80 | | INPUT | OUTPUT | 81 | | ------ | ------ | 82 | | 57 | 11 2 | 83 | | 269 | 53 4 | 84 | 85 |
86 | 87 | ## Question 8 88 | 89 | Guess the outcome of each statement. Then check the results. 90 | 91 | Hint: You can multiply strings with integers. It basically performs the concatenation operation n many times. 92 |
93 | 94 | * print(int('6') + int('4'))
95 | * print('1' + '4')
96 | * print(int(3.9)) 97 | * print(str(5.3) + '2.7')
98 | * print(int('5') * str(0.6))
99 | * print(float('3' + '8.6'))
100 | * print(3.5 + 6.7)
101 | * print(2 ** 3 ** 2 / 32) 102 | * print(str(4.4) + str(7.3))
103 | * print(int(6.5) + float('6.5'))
104 | * print(int(4.5 + 3.2))
105 | * print(int(3.2) + int(float(str(3.2))))
106 | 107 | Remarks: 108 |
109 | 110 | * Observe that float-to-int type conversion is not a rounding operation. int(3.9) = 3. To round floats, we will use a built-in function called round(). Stay tuned!
111 | * As you see, we can multiply strings with integers, but not floats. What does 3.14 times "pi" mean, anyway?
112 | * Exponent operator ** has right-to-left associativity.
113 | 114 |
115 | 116 | ## Question 9 117 | 118 | We want to simulate a division operation. In order to do that, write a program to prompt the user for 2 integers, dividend and divisor respectively. Perform the division operation and print out the quotient and the remainder. 119 | 120 | | INPUT | OUTPUT | 121 | | ------ | ------ | 122 | | 9 2 | quotient = 4 remainder = 1| 123 | | 156 13 | quotient = 12 remainder = 0 | 124 | | 84 16 | quotient = 5 remainder = 4 | 125 | 126 |
127 | 128 | ## Question 10 129 | 130 | In mathematics and computer science, the [floor function](https://en.wikipedia.org/wiki/Floor_and_ceiling_functions) is the function that takes as input a real number
x, and gives as output the greatest integer less than or equal to x, denoted as `⌊x⌋`. The fractional part is the sawtooth function, denoted by `{x}` for real x and defined by the formula `{x} = x - ⌊x⌋`. Write a function that takes 3 positive floats from the input and prints out the fractional part of each value respectively. Do not use float-to-int type casting. There might occur some [floating-point error](https://www.geeksforgeeks.org/floating-point-error-in-python/), you do not have to deal with that. 131 | Hint: Integer division by 1 can be helpful to find `⌊x⌋`. Notice that for negative numbers, we have to perform extra steps to find `⌊x⌋`. 132 | 133 | | INPUT | OUTPUT | 134 | | ------ | ------ | 135 | | 4.8 6.4 3.5| 0.8 0.4 0.5| 136 | | 67.32 23.53 13.98 | 0.32 0.53 0.98 | 137 | | 65.12 49.32 30.09 | 0.12 0.32 0.09 | 138 | 139 |
