How do Programming Languages work?

Programming languages work as a bridge between human-readable instructions and machine-executable code. Here’s a breakdown of how programming languages function:

1. Writing code (Syntax and Semantics)

Programming languages have specific rules for writing code:

  • Syntax: Defines the structure and format of valid statements in the language. It includes rules for variables, expressions, control structures (loops, conditionals), and functions.
  • Semantics: Determines the meaning and behavior of these constructs. It specifies how operations are performed, how data types interact, and the expected outcomes of expressions and statements.

2. Compilation vs Interpretation

Compilation

  • Process: In compiled languages (e.g., C, C++):
  • Compilation: Code is translated from high-level source code to low-level machine code (binary) by a compiler.
  • Object Code: Compiler produces object files (machine code) that are linked together into an executable file.
  • Execution: The executable file contains instructions directly executable by the CPU.
  • Advantages: Faster execution as code is pre-translated into machine code. Optimizations can be applied during compilation for efficiency.
  • Disadvantages: Requires a compilation step before execution. Less flexibility for dynamic changes at runtime.

Interpretation

  • Process: In interpreted languages (e.g., Python, JavaScript):
  • Execution: Code is read and executed line-by-line or in chunks by an interpreter at runtime.
  • Dynamic Typing: Data types are determined at runtime, allowing for flexibility but potentially slower execution.
  • Bytecode: Some languages use intermediate bytecode (e.g., Java bytecode) which is interpreted or compiled Just-In-Time (JIT) for execution.
  • Advantages: Easier debugging and dynamic programming. No separate compilation step needed.
  • Disadvantages: Generally slower execution compared to compiled languages. Interpreter overhead can affect performance.

3. Execution Process
