# 1.1 Introduction to Algorithms, Programming and Compilers

#### Topic 1.1 — Introduction to Algorithms, Programming, and Compilers

**Suggested Skills:** 1.A

**LO 1.1.A** — Represent patterns and algorithms found in everyday life using written language or diagrams.

* **1.1.A.1** — Algorithms define step-by-step processes to follow when completing a task or solving a problem. These algorithms can be represented using written language or diagrams.
* **1.1.A.2** — Sequencing defines an order for when steps in a process are completed. Steps in a process are completed one at a time.

**LO 1.1.B** — Explain the code compilation and execution process.

* **1.1.B.1** — Code can be written in any text editor; however, an integrated development environment (IDE) is often used to write programs because it provides tools for a programmer to write, compile, and run code.
* **1.1.B.2** — A compiler checks code for some errors. Errors detectable by the compiler need to be fixed before the program can be run.

**LO 1.1.C** — Identify types of programming errors.

* **1.1.C.1** — A **syntax error** is a mistake in the program where the rules of the programming language are not followed. These errors are detected by the compiler.
* **1.1.C.2** — A **logic error** is a mistake in the algorithm or program that causes it to behave incorrectly or unexpectedly. These errors are detected by testing the program with specific data to see if it produces the expected outcome.
* **1.1.C.3** — A **run-time error** is a mistake in the program that occurs during the execution of a program. Run-time errors typically cause the program to terminate abnormally.
* **1.1.C.4** — An **exception** is a type of run-time error that occurs as a result of an unexpected error that was not detected by the compiler. It interrupts the normal flow of the program's execution.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://www.computersciencea.com/unit-1-using-objects-and-methods/1.1-introduction-to-algorithms-programming-and-compilers.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
