📘 WHAT ARE PROGRAMMING LANGUAGES?
🔹 Introduction
· A programming language is a structured method for communicating with computers.
· It allows developers to give instructions in a way machines can interpret.
· At its core, a program is a set of commands that tells a computer what to do.
· Without programming languages, we would need to write software directly in binary (0s and 1s).
· That would be extremely complex and error-prone.
· Programming languages make development faster, easier, and more human-friendly.
· They are the backbone of every application, from mobile apps to supercomputers.
· Today, thousands of programming languages exist.
· Each one serves different purposes and industries.
· In this series, we’ll explore all major programming languages with pros, cons, and examples.
🔹 Historical Evolution
· Machine Code (1940s) → Direct binary instructions.
· Assembly Language (1950s) → Symbolic representation of binary.
· FORTRAN (1957) → First high-level scientific language.
· COBOL (1959) → Designed for business computing.
· ALGOL (1960) → Inspired later languages like C, Pascal, and Java.
· C (1972) → Gave rise to C++, Objective-C, and many others.
· Smalltalk (1972) → First true Object-Oriented Language.
· C++ (1985) → Added OOP to C.
· Java (1995) → “Write Once, Run Anywhere.”
· Python (1991) and JavaScript (1995) → Ushered in modern programming.
🔹 Types of Programming Languages
· Low-Level Languages → Machine Code, Assembly.
· High-Level Languages → Python, Java, C#.
· Procedural Languages → C, Pascal.
· Object-Oriented Languages → Java, C++, Python.
· Functional Languages → Haskell, Lisp, Scala.
· Scripting Languages → JavaScript, PHP, Ruby.
· Domain-Specific Languages → SQL, MATLAB, HTML.
· Multi-Paradigm Languages → Kotlin, Swift, Python.
· Compiled Languages → C, Rust, Go.
· Interpreted Languages → Python, JavaScript, Ruby.
🔹 Top 10 Programming Languages
