Calculator-N-Operands (C++)

Overview

This project implements a simple yet customizable calculator using C++. It supports four basic arithmetic operations—addition, subtraction, multiplication, and division—while allowing users to input the number of operands for the selected operation.

Features

• Dynamic operand count: The calculator can process multiple operands provided by the user, performing the chosen operation across all inputs.
• Basic arithmetic operations: Includes addition (+), subtraction (-), multiplication (*), and division (/).
• Efficient code structure: Uses switch cases and loops to handle different operations and iterate through operands.

How It Works

1. The user specifies the number of operands (n).
2. The operands are then stored in a dynamically created array.
3. Depending on the operation (+, -, *, /) chosen by the user, the program performs the corresponding arithmetic on all operands.

Time and Space Complexity

• Time Complexity:

  • Input Reading: O(n)
  • Initialization: O(n)
  • Operation Execution: O(n-1)
  • Overall: O(n)

• Space Complexity:

  • Operand storage: O(n)
  • Additional variables: O(1)
  • Overall: O(n)

Example Usage

Enter an operator (+, -, *, /): +
Enter Number of Operands: 3
Enter 3 operands below:
5 3 2
5 + 3 + 2 = 10
