The best way to solidify your understanding of C programming is by building something practical. In this project, we will create a <strong>simple command-line calculator</strong>. This will allow you to apply many of the concepts we&rsquo;ve covered so far:</p> <ul> <li><strong>Functions:</strong> To encapsulate arithmetic operations.</li> <li><strong>Control Flow:</strong> For handling different operations and error conditions.</li> <li><strong>Data Types and Operators:</strong> For performing calculations.</li> <li><strong>Command-Line Arguments (<code>argc</code>, <code>argv</code>):</strong> For accepting user input.</li> <li><strong>String to Number Conversion:</strong> Using <code>atoi</code> or <code>strtol</code>.</li> </ul> <p>The goal is to create a program that can be run from the terminal like this:</p>
