We can't use keywords for our own purposes.</li> <li>There are a total of 32 keywords in C which are as follows:</li> </ul> <div class="table-wrapper-paragraph"><table> <thead> <tr> <th></th> <th></th> <th></th> <th></th> </tr> </thead> <tbody> <tr> <td>auto</td> <td>break</td> <td>case</td> <td>char</td> </tr> <tr> <td>const</td> <td>continue</td> <td>default</td> <td>do</td> </tr> <tr> <td>double</td> <td>else</td> <td>enum</td> <td>extern</td> </tr> <tr> <td>float</td> <td>for</td> <td>goto</td> <td>if</td> </tr> <tr> <td>int</td> <td>long</td> <td>register</td> <td>return</td> </tr> <tr> <td>short</td> <td>signed</td> <td>sizeof</td> <td>static</td> </tr> <tr> <td>struct</td> <td>switch</td> <td>typedef</td> <td>union</td> </tr> <tr> <td>unsigned</td> <td>void</td> <td>volatile</td> <td>while</td> </tr> </tbody> </table></div> <h2> Operators </h2> <ul> <li>Special types of symbols i.e. are used to perform specific task</li> <li>Types: Binary operator, Unary operator, Ternary operator, etc.</li> <li>Total 44 operators are present</li> </ul> <h2> Separators: </h2> <ul> <li>Separate things called as a token</li> <li>we can separate individual unit -&gt; token</li> </ul> <blockquote> <p>What is Token</p> <blockquote> <p>The smallest unit of c programming is known as a token. Token can be any keyword, operator, separator, constant, identifier, etc. We can give any number of spaces between tokens.</p> </blockquote> </blockquote> <h2> Constant </h2> <ul> <li>Variable that doesn't change its value throughout the program is known as a constant.</li> <li>Types: <ul> <li>Alphanumeric constants -&gt; a-z, A-z, 0-9</li> <li>Numeric constants -&gt; 0-9</li> </ul> </li> </ul> <h2> Predefined Function </h2> <ul> <li>all predefined functions are stored in respective header files.</li> <li>e.g. <ul> <li>stdio.h -&gt; printf(), scanf(), ...</li> <li>math.h -&gt; sqrt(), ...</li> </ul> </li> </ul> <h2> Syntax </h2> <ul> <li>Syntax is the rules which need to be followed while developing a program</li> <li>e.g. To declare variable syntax is - data_type variable_name ;</li> </ul>
