• Reversing and rotating arrays
• Removing duplicate values
• Calculating sums and averages

arrays/2D_Arrays

Contains exercises involving matrices and two-dimensional arrays, such as:

• Matrix input and output
• Matrix addition and subtraction
• Matrix multiplication
• Matrix transpose
• Row and column operations
• Sum of matrix elements

basics

Contains foundational C++ programs covering:

• Arithmetic operations
• Conditional statements
• Loops
• Number checks
• Prime numbers
• Factorials
• Palindromes
• Leap years
• Multiplication tables
• Character checks
• Eligibility-based programs

funtions/conversion

Contains conversion programs written with reusable functions:

• BinaryToDecimal.cpp - Converts a binary number to decimal

🛠️ Requirements

To compile and run these programs, install:

• A C++ compiler supporting C++17 or newer
• Visual Studio Code, CLion, Code::Blocks, or another C++ IDE
• Git for cloning and managing the repository

Recommended compiler:

g++ (MinGW-w64 on Windows)

---

▶️ Compile and Run

Open a terminal in the repository and compile a program with:

g++ "path/to/program.cpp" -o bin/program

Example:

g++ "funtions/conversion/BinaryToDecimal.cpp" -o bin/BinaryToDecimal

Run the compiled program on Windows:

bin\BinaryToDecimal.exe

Run it on Linux or macOS:

./bin/BinaryToDecimal

🎯 Purpose

The main goals of this repository are to:

1. Build a strong foundation in C++.
2. Practise translating problems into working code.
3. Improve logical and algorithmic thinking.
4. Learn how functions improve code reuse and organisation.
5. Maintain an organised record of learning progress.
6. Prepare for object-oriented programming, data structures, and algorithms.

📝 Notes

• Each source file focuses on a specific concept or exercise.
• Source files are organised by topic.
• Compiled executable files are stored inside the bin folder.
• New programs and folders will be added as learning progresses.
• Descriptive file names make exercises easier to locate.
