# Code Snippets in Lecture Materials

- Videos and slides (for both live lectures and videos) are available from Canvas
- When watching videos/attending lectures, **access the slides for code examples you can run locally/in your browser:**

```c
#include <stdio.h>

int main() {
    printf("hello, world!\n");
    return 0;
}
```
.codelink[<a href="src/hello-world.c" download>`00-logistics/hello-world.c`</a>  <a href="https://github.com/olivierpierre/comp60261-devcontainer" target="_blank" style="text-decoration: none"><img src="include/gh-logo.svg" style="height: 1em"></a>]

- Sometimes there is not enough space on a slide to put a fully compilable program
  - May omit e.g. header inclusions and error-checking code
  - **The downloadable versions are always fully working examples**
