Introduction to Functions: Building a Basic Calculator Program in C++

Take your C++ skills to the next level by building a versatile calculator program! In this beginner-friendly task, you'll dive into functions, enabling you to create a calculator that can perform various operations based on user input.

**Task:**
Your challenge is to develop a C++ program that functions as a basic calculator. Create separate functions for addition, subtraction, multiplication, and division operations. Allow the user to choose an operation and input two numbers, then display the result.

**Instructions:**
1. Fork this repository to your GitHub account.
2. Clone the forked repository to your local machine: `git clone https://github.com/KALIIOWORK/basic_c-_programs.git`
3. Create a new C++ file named `calculator_functions.cpp`.
4. Write separate functions for addition, subtraction, multiplication, and division.
5. Implement a main function that takes user input for the operation and two numbers.
6. Call the corresponding function based on the user's choice and display the result.
7. Test your calculator program with different input scenarios to ensure its accuracy.
8. Compile and run your program to confirm it works as expected.
9. Commit your changes and push them to your forked repository.
10. Open a pull request with your changes.

**Note:**
This task will strengthen your understanding of functions and user input handling in C++. Building a functional calculator is a great way to apply your knowledge. Have fun coding! 🧮✨
