SamipPandey-kec/Second-semester ? reverse-engineered prompt

Build me a clean GitHub repo for my second semester C++ programming lab work.

I want it organized into clear folders for assignments, class work, and lab exercises, with each week or lab having small standalone C++ programs that show the basics like input and output, loops, functions, arrays, classes, constructors, destructors, pointers, friend functions, operator overloading, inheritance, polymorphism, dynamic binding, casting, and simple error handling.

Please make the code easy to read, beginner friendly, and consistent across files. Add a simple README that explains what the repository is for and what topics are covered, so someone can quickly understand it. If anything needs a small example or comment to make it easier for a student to follow, add that too. Look up current C++ docs online if you need to make the examples cleaner or more correct.
