Welcome to C++ Project 2 - Simple Calculator

This project will guide you through creating a simple calculator in C++ that can perform basic arithmetic operations like addition, subtraction, multiplication, and division.

Hardware Setup

Ensure you have the following hardware components:

A computer with internet access.
A keyboard and mouse for typing and navigation.

Software Requirements

Here are the software tools you'll need for this project:

Visual Studio Code or CLion - These are popular Integrated Development Environments (IDEs) for C++ development.
GCC or Visual Studio - Required to compile and run C++ programs.

Knowledge Prerequisites

To successfully complete this project, you should be familiar with the following concepts:

Basic understanding of C++ syntax.
Understanding of arithmetic operations in C++.

Project Steps:

Done

Download and install Visual Studio Code or CLion.
Ensure you have a C++ compiler installed. For example, you can install GCC or use the built-in compiler in Visual Studio.

Done

Open your chosen IDE (Visual Studio Code or CLion).
Create a new file named simple_calculator.cpp.

Done

Open the simple_calculator.cpp file in your IDE.

Type the following code:


#include <iostream>

int main() {
    char op;
    float num1, num2;

    std::cout << "Enter operator (+, -, *, /): ";
    std::cin >> op;

    std::cout << "Enter two operands: ";
    std::cin >> num1 >> num2;

    switch(op) {
        case '+':
            std::cout << num1 << " + " << num2 << " = " << num1 + num2 << std::endl;
            break;
        case '-':
            std::cout << num1 << " - " << num2 << " = " << num1 - num2 << std::endl;
            break;
        case '*':
            std::cout << num1 << " * " << num2 << " = " << num1 * num2 << std::endl;
            break;
        case '/':
            std::cout << num1 << " / " << num2 << " = " << num1 / num2 << std::endl;
            break;
        default:
            std::cout << "Error! operator is not correct" << std::endl;
            break;
    }

    return 0;
}

Save the file.

Done

Open the terminal in your IDE and navigate to the directory containing simple_calculator.cpp.
Type the following command to compile your application:
```
g++ simple_calculator.cpp -o simple_calculator
```
Type the following command to run your application:
```
./simple_calculator
```
You should be able to perform basic arithmetic operations by entering the operator and operands when prompted.
