True B.

True<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<p>Library functions in the C programming language <strong>are indeed pre-defined built-in functions<\/strong> that are permanently stored in the library of the C compiler. These functions are provided by the creators of the C language to help programmers perform common tasks more efficiently without the need to write the code from scratch.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">What are Library Functions?<\/h4>\n\n\n\n<p>Library functions are ready-to-use functions grouped in header files (like <code>stdio.h<\/code>, <code>math.h<\/code>, <code>string.h<\/code>, etc.). Examples of common library functions include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>printf()<\/code> and <code>scanf()<\/code> for input\/output operations (in <code>stdio.h<\/code>)<\/li>\n\n\n\n<li><code>strlen()<\/code>, <code>strcpy()<\/code> for string handling (in <code>string.h<\/code>)<\/li>\n\n\n\n<li><code>sqrt()<\/code>, <code>pow()<\/code> for mathematical computations (in <code>math.h<\/code>)<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Why Use Library Functions?<\/h4>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Saves Time<\/strong>: You don\u2019t need to manually code complex functionality.<\/li>\n\n\n\n<li><strong>Reliable<\/strong>: These functions are thoroughly tested and optimized.<\/li>\n\n\n\n<li><strong>Portability<\/strong>: Code using standard library functions works across different platforms and compilers.<\/li>\n<\/ol>\n\n\n\n<h4 class=\"wp-block-heading\">How They Work:<\/h4>\n\n\n\n<p>To use a library function, the relevant header file must be included at the beginning of the C program using the <code>#include<\/code> directive. For example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>#include &lt;stdio.h&gt;\n\nint main() {\n    printf(\"Hello, World!\");\n    return 0;\n}\n<\/code><\/pre>\n\n\n\n<p>Here, <code>printf()<\/code> is a library function that prints text to the screen and is defined in the <code>stdio.h<\/code> library.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Conclusion:<\/h4>\n\n\n\n<p>Thus, the statement that \u201cLibrary Functions are pre-defined built-in functions that are permanently stored in the library of C compiler\u201d is <strong>True<\/strong>. These functions form an essential part of C programming, allowing developers to write efficient, reliable, and standardized code.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Library Functions are pre-defined built-in functions that are permanently stored in the library of C compiler.
