Core programming fundamentals and DSA practice across C, C++, Java, and Python — built while strengthening OOP concepts and problem-solving basics from the ground up.
| Folder | Focus |
|---|---|
C-basics |
Core C syntax — control flow, functions, file handling |
CPP-Basics |
C++ with OOP — classes, constructors, inheritance, polymorphism, STL vectors, file I/O |
Java-Basics |
Java fundamentals & OOP — encapsulation, abstraction, interfaces, exceptions, collections |
Python-Basics |
Python scripting — calculators, file/JSON handling, validators, small CLI tools |
DSA-Arrays-Strings |
Array/string problems (reverse array, remove duplicates, longest common prefix) in C++ and Python |
DSA/Sorting |
Bubble, insertion, selection sort — implemented in both C++ and Python |
DSA/Searching |
Linear and binary search — implemented in both C++ and Python |
Each language/topic folder has its own README with the full list of programs inside.
