Lab 4

Labs are practice problems which, time permitting, may be started or completed in your section, and are assessed on correctness only. You are encouraged to collaborate with classmates on this lab, though each member in a group collaborating is expected to contribute equally to the lab.

What to Do

Log into code.cs50.io using your GitHub account
Run update50 in your codespace’s terminal window to ensure your codespace is up-to-date and, when prompted, click Rebuild now
Submit one of:
- Smiley
  Getting Started
  
  Start by clicking inside your terminal window, then execute cd by itself. You should find that its “prompt” resembles the below.
```
$
```
  Click inside of that terminal window and then execute
```
wget https://cdn.cs50.net/2022/fall/labs/4/smiley.zip
```
  followed by Enter in order to download a ZIP called smiley.zip in your codespace. Take care not to overlook the space between wget and the following URL, or any other character for that matter!
  
  Now execute
```
unzip smiley.zip
```
  to create a folder called smiley. You no longer need the ZIP file, so you can execute
```
rm smiley.zip
```
  and respond with “y” followed by Enter at the prompt to remove the ZIP file you downloaded. Finally, right-click or control-click on the smiley folder and click “Open in CS50 Lab”. You should see the specification for this problem on the left-hand side and its distribution code on the right-hand side.
