Programming is the process of writing instructions for computers. It is how humans tell machines what to do. The instructions are written in programming languages, then translated into machine code by compilers or interpreters. Programming is part logic, part creativity, part problem-solving.

Programmers break big problems into small steps. They write code, test it, fix bugs, and repeat. They read documentation. They collaborate with others. They learn new languages and tools constantly. The field changes fast. What you know today may be obsolete in five years.

Paradigms of programming

• Procedural: step-by-step instructions
• Object-oriented: objects with data and methods
• Functional: pure functions and immutable data
• Declarative: describe what, not how
• Event-driven: respond to events

Programming is not just for software engineers. Scientists write code to analyze data. Artists write code to create generative art. Marketers write code to automate campaigns. The ability to program is becoming a basic literacy, like reading and math.
