Atreyawebs - Learning Management System

Description

This course provides a unified foundation in programming through a comparative study of four major languages — C, C++, Java, and Python. Learners explore the core principles of programming logic, syntax, and structure while understanding how these concepts are implemented differently across languages. The curriculum emphasizes conceptual clarity, hands-on coding, and cross-language learning, enabling students to write, analyze, and debug programs effectively.

Through progressive chapters and structured classes, students will move from understanding programming basics and execution flow to mastering control structures, functions, data handling, and object-oriented programming concepts. The course concludes with a mini project that integrates all learned concepts into a real-world programming solution.
