Study Notes
Coding Basics
-
Coding is the process of instructing a computer to perform specific tasks. This is achieved by writing code in a programming language.
-
Programming languages are sets of rules and syntax that computers can understand. This allows programmers to translate human-readable instructions into machine-executable commands.
-
Code is composed of statements, instructions, and expressions that tell the computer what to do. The arrangement of these elements dictates the computer's actions.
Programming Languages
-
Numerous programming languages exist, each with unique strengths and weaknesses. Common languages include JavaScript, Python, Java, C++, and C#.
-
Languages often specialize in particular domains, such as web development (JavaScript, HTML, CSS), data science (Python), mobile app development (Swift, Kotlin), or game development (C++).
-
The choice of language depends on factors like project requirements, developer experience, and platform compatibility.
Strings
-
In programming, a string is a sequence of characters. It can represent text, labels, or any other character-based data.
-
Strings are commonly used to store and manipulate textual information. This includes everything from simple words to complex paragraphs.
-
Strings are typically enclosed in quotation marks (e.g., "Hello," 'World'). Programming languages have specific rules for the characters used within quotation marks.
-
Operations on strings include concatenation (joining strings together), accessing individual characters, and searching for specific substrings.
-
String manipulation involves methods for formatting text, converting to upper/lower case, and removing extraneous characters.
-
String handling is a vital aspect of many programs since so much data is textual, requiring formatting, display or analysis.
-
String lengths vary greatly depending on the task; a short phrase or name might be a few characters long, while a novel or a document could be millions.
-
Strings are often used as input/output for user interfaces.
