University C++ Lab Programs

A collection of C/C++ programs written during university laboratory classes, examinations, and practice sessions.

These programs are preserved as educational material. The original/ directory contains the historical source files as they were supplied, while modern/ contains cleaned-up C++ versions intended to compile with a modern C++ compiler.

Batch 01

Original	Topic	Modern version

Q-SORT.CPP	Quick sort	modern/quick_sort.cpp
REPLACE.CPP	String replacement	modern/string_replace.cpp

Why are there two versions?

The original programs are part of the historical record of the university lab work. They use older Turbo C/C++ conventions such as conio.h, clrscr(), getch(), delay(), goto, one-based array indexing, and void main().

The modern versions keep the educational purpose of the programs while using standard C++ facilities such as:

• iostream
• vector
• string
• standard algorithms
• int main()
• zero-based internal indexing

User-visible positions are still displayed starting from 1 to make them easier to compare with the original programs.

Compile

Example with GCC/G++:

g++ -std=c++17 modern/bubble_sort.cpp -o bubble_sort

Then run the resulting executable.

Educational note

These are simple laboratory/practice implementations, not production-quality implementations. They are intentionally useful for learning basic algorithms and data structures.

Historical note

The original source comments contain dates, course/semester references, and the coding style used at the time. They have been retained rather than rewritten.
