Kotlin Calculator 😀

A simple command-line calculator application built with Kotlin.

Features 💥

• Perform basic arithmetic operations: addition (+), subtraction (-), multiplication (*), and division (/).
• Calculate square roots (sqrt) and power operations (^).
• Input numbers and operators interactively.
• Continuously calculate until you decide to finish with '='.
• Handles division by zero gracefully.
• View calculation history.
• Clear current result and start a new calculation.

Usage 👨🏻‍💻

1. Clone the repository:

   `git clone https://github.com/swaraj-das/Kotlin-Calculator.git`

2. Navigate to the project directory:

   `cd Kotlin-Calculator`

3. Compile and run the Kotlin code:

   `kotlinc Calculator.kt -include-runtime -d Calculator.jar`
   `java -jar Calculator.jar`
   

4. Follow the on-screen instructions to perform calculations.

Example 📝

...Welcome to Kotlin Calculator...

Enter first number: 5
Enter operator (+, -, *, /, sqrt, ^, c, h) or '=' to finish: +
Enter next number: 1
Current result: 6.0
Enter operator (+, -, *, /, sqrt, ^, c, h) or '=' to finish: ^
Enter next number: 2
Current result: 36.0 Enter operator (+, -, *, /, sqrt, ^, c, h) or '=' to finish: c
Result cleared. Start a new calculation.
Enter first number: 1
Enter operator (+, -, *, /, sqrt, ^, c, h) or '=' to finish: -
Enter next number: 2
Current result: -1.0
Enter operator (+, -, *, /, sqrt, ^, c, h) or '=' to finish: h
Calculation history:
5.0 + 1.0 = 6.0
6.0 ^ 2.0 = 36.0
1.0 - 2.0 = -1.0
Enter operator (+, -, *, /, sqrt, ^, c, h) or '=' to finish: '='
Final result: -1.0
