Programming Languages Fundamentals

Programming Language एक Formal Language होती है जिसका उपयोग Computer को Instructions देने के लिए किया जाता है। Computer केवल Machine Language को समझता है, इसलिए Programming Languages का उपयोग Human Readable Instructions को Computer Executable Form में बदलने के लिए किया जाता है।

Introduction

Computer Programming आधुनिक Software Development का आधार है। किसी भी Software, Mobile Application, Website, Operating System या Artificial Intelligence System को विकसित करने के लिए Programming Languages का उपयोग किया जाता है।

Programming Language Programmer तथा Computer के बीच Communication Medium का कार्य करती है।

Definition

Programming Language नियमों, Keywords तथा Syntax का ऐसा समूह है जिसके माध्यम से Computer Programs लिखे जाते हैं।

Programming Language = Instructions + Syntax + Logic
