# Unit Overview

- **Year-long unit** that aims to cover the **principles of different programming language paradigms**
  - Compare and contrast the advantages and disadvantages of the imperative and functional programming paradigms
  - Describe the key principles of compilation
  - Highlight the impact of modern trends on programming languages.

# Unit Content

- Part 1 (5 weeks): **Imperative Programming (C)**
  - Pierre Olivier (C, 5 weeks)

--
- Part 2 (5 weeks): **Compilation, Program Translation**
  - Rizos Sakellariou

--
- Part 3 (3 weeks): **Object-Oriented Programming (C++)**
  - Pavlos Petoumenos

--
- Part 4 (5 weeks): **Functional Programming (Haskell)**
  - Joe Razavi

--
- Part 5 (3 weeks): **Advanced topics, Concurrency**
  - Joe Razavi, Pavlos Petoumenos

Each part is self-contained, managed by its instructor

---
# Unit Organisation

- **Blended approach**: mix of live sessions, and asynchronous material (videos, exercises, etc)
  - Live session once a week
  - Support sessions ("lab"): basically office hours, drop-in for questions, feedback, etc.
  - Everything is accessible from Canvas
--

- **Assessment**:
  - 70% final exam in May/June
  - 30% laboratory exercises
      - Five exercises in total: each one carries a different weight
      - No lab session per se, to be done on your free time
      - NB: the solution you submit has to be your own work!
--
- Advice: don’t stay behind!

---
# How to Get Help?

- **Ask questions**:
  - In live lectures
  - In timetabled support sessions:
      - They are staffed (course unit lecturers and possibly Graduate Teaching Assistants - GTAs): people are there to help!
  - Use Canvas's discussion boards: encouraged!
--

- **Think before emailing the instructors**:
  - You are 300+
  - Only email instructors for critical/urgent matters

---
# Part 1/C Organisation

**Blended approach**: live sessions + asynchronous videos & exercises

---
# Part 1/C Organisation

1. **Lecture materials**:
  - Live lecture every Monday 12pm-1pm, located in *Simon Building Lecture Theatre B*
  - A set of videos to watch every week **after the lecture**
--

2. **Formative assessment** (not graded), every week:
  - Quiz (theory) + autocorrected programming exercises (practice)
  - To do every week **after reviewing the lecture materials**
--

3. **Summative assessment** (marked): 1 lab exercise, to be done on your free time at home and/or on the Department's machines
--

4. **Support sessions**
  - Come if you have any questions about the lecture materials and formative/summative exercises
  - Every other week starting week of 06/10, Friday 12pm-2pm in Kilburn LF31

# Course Website

.large[On Canvas: https://canvas.manchester.ac.uk/courses/43660]

- **Everything regarding part 1/C can be accessed from there:**
  - Schedule (what to do each week)
  - Videos, including live sessions recordings
  - Lecture notes and lecture slides
  - Summative lab exercise brief
  - Formative autocorrected programming exercises
  - Formative quizzes
  - Discussion board
  - Reading list

---
# Required Software

All programming exercises should be done in a Linux
🐧x86-64 (i.e. Intel CPU) environment with GCC 10-13. Several solutions:

- **Use the Department's machines**
- **Run Linux in an x86-64 VM**
  - Grab a VirtualBox VM image here: https://bit.ly/4nfHv9f
--

- **Install Linux natively on your x86-64 machine**
  - If you know what you are doing
  - Ubuntu 22.04 recommended
--

- **⚠️ Do NOT use native Windows/Mac or WSL environments ⚠️**
  - Won't provide support on these, and you may lose marks because of toolchain
    difference
--
- **MacBooks with non-Intel (i.e. M1) CPUs**: some solutions given next, but the general advice is to come on campus and use lab machines

---

# Lecture Videos

- Videos and slides available on Canvas

--
- When watching videos/attending lecture, **access the slides for code examples you can run in your browser**:
  - https://olivierpierre.github.io/comp26020
--

- Using the bottom-right links you can:
  - Download the file: click on the blue path
  - Get instructions on how to load and run it in a container that should run on Mac/Windows by clicking on the GitHub logo <img src="include/gh-logo.svg" style="height: 1em" >

```c
#include <stdio.h>

int main() {
    printf("hello, world!\n");
    return 0;
}
```

# Lecture Notes

- https://olivierpierre.github.io/comp26020/
- Cover the same things as video but in written form
- No need to read if you fully understand the lecture materials covered in the live session and videos
  - Useful if things are not 100% clear
  - Should also be useful for revision before the exams

---
# Feedback on Lectures

- Each slides deck ends with a link to a small feedback form
- It's fully optional and anonymous, feel free to use it to tell what you think about the lecture in question
  - Your feedback will help to make the course better!

---
# Lab Assignment (marked)

- Subject is already on Canvas
- Development of a matrix processing library in C
- Weight: 6.5% of the final COMP26020 mark 
  - **50/50 coursework/exam weight split for the C part**

---

## Autocorrected Programming Exercises (not marked)

- A few exercises per week:
  - Example here: https://olivierpierre.github.io/comp26020/exercise-set-2.html
  - Divided into **essential** and **additional** exercises
--

- Autocorrected with `check50`
- To trigger autocorrection, have your source code in the local folder and type
  on the command line:

```bash
check50 -l --ansi-log <exercise URL>
```

- URL is per-exercise, given on the page of each exercise

--
- Accessible from the website, along with instructions on how to install `check50`: https://olivierpierre.github.io/comp26020/exercise-set-1.html

---

# Quizzes

- A small quiz to complete each week, after having seen all the lecture materials
  - On Canvas
  - Formative (unmarked)

# How to Get Help?

- Any question? In increasing order or urgency:
  - Step 1: come to the next support session
  - Step 2: discussion boards on Canvas
      - **Do not post answers there!**
  - Step 3 (only if urgent): [pierre.olivier@manchester.ac.uk](mailto:pierre.olivier@manchester.ac.uk)
