Introduction to Programming Languages
Definition:
Programming languages are formal languages comprising a set of instructions
that produce various kinds of output. They are used to communicate with computers
and create software applications.
Categories of Programming Languages:
Low-level languages: These are closer to machine code and include:
1. Machine language: The only language understood by computers (binary
code).
2. Assembly language: Uses symbolic representations of machine
instructions, making it slightly easier than machine code.
High-level languages: These are more abstract and closer to human languages,
such as:
1. Procedural languages: Follow a sequence of instructions (e.g., C,
Pascal).
2. Object-oriented languages (OOP): Based on objects and classes (e.g.,
Java, C++).
3. Scripting languages: Often interpreted and used for automation (e.g.,
Python, JavaScript).
4. Functional languages: Focus on functions and immutability (e.g.,
Haskell, Lisp).
Importance of Programming Languages:
o Enable software development for applications, games, and systems.
o Facilitate problem-solving by providing tools to model and simulate
real-world situations.
o Drive innovation in industries such as AI, web development, and data
analysis.
