Making a Simple Calculator Using C | Challenge

# Introduction

In this project, we will learn how to create a simple calculator using the C programming language. The calculator will be capable of performing basic arithmetic operations such as addition, subtraction, multiplication, and division. We will also implement checks to ensure that the user input is valid and handle cases where the input leads to undefined behavior.

## 👀 Preview

$ ./Calculator
32+11
=43.000000

$ ./Calculator
41-34.9
=6.100000

$ ./Calculator
10/2
=5.000000

$ ./Calculator
2*4
=8.000000

$ ./Calculator
10%3
=1

## 🎯 Tasks

In this project, you will learn to:

- Get user input in C using `scanf()`
- Check the format of the input arithmetic expression
- Perform arithmetic calculations based on the user input
- Handle division by zero errors
- Implement the remainder operator only for integer operands

## 🏆 Achievements

In this project, you will learn:

- How to get user input in C
- How to handle different arithmetic operations
- How to perform error checking and handle invalid input
- How to compile and run C programs using the `gcc` compiler
