variable is by using the literal constant &#8220;NULL.&#8221; This constant represents a null pointer and is defined in the header file <code>stddef.h<\/code>. To assign a null value, use the following syntax:\n<\/p>\n<pre><br \/>\n<code><br \/>\nint* ptr = NULL;<br \/>\n<\/code><br \/>\n<\/pre>\n<p>\nIn this example, we are assigning a null value to an integer pointer named <code>ptr<\/code>.\n<\/p>\n<p><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Method_2_Using_the_Null_Pointer_Constant\"><\/span>Method 2: Using the Null Pointer Constant<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>\nIn C, the null pointer constant is represented by <code>((void*)0)<\/code>. It is another valid way to assign a null value to a pointer or variable. Here&#8217;s an example:\n<\/p>\n<pre><br \/>\n<code><br \/>\nint* ptr = ((void*)0);<br \/>\n<\/code><br \/>\n<\/pre>\n<h2><span class=\"ez-toc-section\" id=\"Method_3_Assigning_Hexadecimal_Zero\"><\/span>Method 3: Assigning Hexadecimal Zero<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>\nAn alternative method to assign a null value is by assigning the hexadecimal value <code>0x00<\/code>. This method is equivalent to assigning <code>NULL<\/code> and can be used interchangeably. Here&#8217;s an example:\n<\/p>\n<pre><br \/>\n<code><br \/>\nint* ptr = 0x00;<br \/>\n<\/code><br \/>\n<\/pre>\n<h2><span class=\"ez-toc-section\" id=\"Method_4_Using_the_macro_definition\"><\/span>Method 4: Using the macro definition<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>\nIf you prefer using a more descriptive approach, you can define your own macro for assigning a null value.
