feat: Implement switch-case arithmetic calculator for two integers

🧠 Logic:
- Reads two integers and a character operator as input.
- Uses a `switch` statement to determine which arithmetic operation to perform: +, -, *, or /.
- For valid operators, prints the result of the operation.
- If the operator is not recognized, prints "Invalid operator".
- Division assumes non-zero denominator as guaranteed by problem constraints.
