<b><br /></b>
<b>String Function:</b><br />
<b><br /></b>
The standard library for C string functions is string.h. This header file defines tons of useful string manipulation functions including:<br />
<ul style="text-align: left;">
<li>strcmp</li>
<li>strcat</li>
<li>strcpy</li>
<li>strlen</li>
</ul>
<div>
<b>strcmp:</b></div>
<div>
strcmp() in C programming language is used to compare two string. If both the strings are equal then it gives the result as zero but if not then it gives the numeric difference between the first non matching character in the string.</div>
<div>
<br /></div>
<div>
<b>Syntax:</b><br />
<b><br /></b></div>
<div>
<pre class="_codebox">int strcmp(const char *str1, const char *str2);
</pre>
<br /></div>
<div>
<b>Example:</b><br />
<b><br /></b></div>
<div>
<pre class="c" name="code">int main()
{
   char str1[30], str2[30];
   printf("Enter first string : ");
   scanf("%s", &str1);
   printf("Enter second string : ");
   scanf("%s", &str2);
   if(strcmp(str1, str2)==0))
      printf("Both strings are equal.")
   else
      printf("strings are not equal.");
   return 0;
}</pre>
<br /></div>
<div>
<b>Output:</b><br />
<b><br /></b>
<br />
<pre class="_codebox">Enter first string : studycodemaster
Enter second string : studycodemaster
Both strings are equal.
</pre>
<b><br /></b>
<b>strcat:</b></div>
<div>
The strcat() function is used for string concatenation in C programming language. Which means this function is used to join the two string together.<br />
<br /></div>
<div>
<b>Syntax:</b><br />
<br /></div>
<pre class="_codebox">strcat(string1, string2);
</pre>
<div>
<br />
<b>Example:</b></div>
<br />
<pre class="c" name="code">int main()
{
   char string1[50]="www.studycodemaster";
   char string2[5]=".blogspot.com";
   printf("Before concatenation the strings are : ");
   printf("\nstring1 : %s", string1);
   printf("\nstring2 : %s", string2);
   printf("\nAfter concatenation the string is : ")
   printf("string : %s", strcat(string1, string2));
   return 0;
}</pre>
<br />
<div>
<b>Output:</b><br />
<b><br /></b>
<br />
<pre class="_codebox">Before concatenation the strings are :
string1 : www.studycodemaster
string2 : .blogspot.com
After concatenation the string is :
string : www.studycodemaster.blogspot.com
</pre>
<b><br /></b>
<b>strcpy:</b></div>
<div>
strcpy() function is used to copies a string from a source location to a destination location and provides a null character to terminate the string.</div>
<br />
<div>
<b>Syntax:</b><br />
<b><br /></b></div>
<div>
<div>
<pre class="_codebox">strcpy(destination, source);
</pre>
<br /></div>
<div>
<b>Example:</b><br />
<b><br /></b></div>
</div>
<div>
<pre class="c" name="code">int main()
{
   char string1[50], string2[50];
   printf("Enter string : ");
   scanf("%s", &string1);
   strcpy(string2, string1);
   printf("string1 : %s ", string1);
   printf("string2 : "%s , string2);
   return 0;
}</pre>
</div>
<br />
<div>
<b>Output:</b><br />
<b><br /></b>
<br />
<pre class="_codebox">Enter string : www.studycodemaster.blogspot.com
string1 : www.studycodemaster.blogspot.com
string2 : www.studycodemaster.blogspot.com
</pre>
<b><br /></b>
<b>strlen:</b></div>
<div>
The strlen() is used to calculate the length of the string. Which means strlen function counts the total number of characters present in the string which includes alphabets, numbers, and all special characters including blank spaces.</div>
<br />
<div>
<b>Syntax:</b><br />
<b><br /></b></div>
<div>
<div>
<pre class="_codebox">count = strlen(stringvariable);

Program to copy the contents of one file into another using fgetc and fputc function

void main()
{
   FILE *fp1,*fp2;
   char a;
   clrscr();

fp1=fopen("test.txt","r");
   if(fp1==NULL)
   {
      puts("cannot open this file");
      exit(1);
   }

fp2=fopen("test1.txt","w");
   if(fp2==NULL)
   {
      puts("Not able to open this file");
      fclose(fp1);
      exit(1);
   }

do
   {
      a=fgetc(fp1);
      fputc(a,fp2);
   }while(a!=EOF);

fcloseall();
   getch();
}
</pre>
<br />
<b>Output:</b><br />
<pre class="_codebox">Content will be written successfully to file
</pre>
<br />
<b>Explanation of Program :</b><br />
<br />
We have to files with us , we are opening one file in read mode and another file in write mode.<br />
<pre class="_codebox">fp1=fopen("test.txt","r");
</pre>
<br />
and<br />
<pre class="_codebox">fp2=fopen("test1.txt","w");
</pre>
<br />
<br />
It is better practice to check whether file is opened successfully or not using NULL check.<br />
<br />
<pre class="_codebox">if(fp2==NULL)
{
   //File is Not opened Successfully

}
</pre>
<br />
If everything goes right then we are reading file character by character and writing on file character by character.<br />
<pre class="_codebox">a=fgetc(fp1); //Reading Single Character
</pre>
<br />
End of File is specified by EOF character, thus if we get EOF character then process of writing on the file will be terminated.<br />
<br />
<pre class="_codebox">do
{
   a=fgetc(fp1);
   fputc(a,fp2);
}while(a!=EOF);
</pre>

What is JavaScript

<div dir="ltr" style="text-align: left;" trbidi="on">
<div style="text-align: justify;">
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiPcNwlEVYAqENI4ium5jeuRYEmu7XCuPsF2q2L5g-xhi2z5pmGCAPq__bU3jaG0496te6lzJhR-CusY7eGsG-Zl1DBKNcrfW_KyLk76Ev1u3Q-fM2c9Cts94Cry3HoCZWPQVqutKKtbUA/s1600/what-is-javascript.png" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img alt="What is JavaScript?" border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiPcNwlEVYAqENI4ium5jeuRYEmu7XCuPsF2q2L5g-xhi2z5pmGCAPq__bU3jaG0496te6lzJhR-CusY7eGsG-Zl1DBKNcrfW_KyLk76Ev1u3Q-fM2c9Cts94Cry3HoCZWPQVqutKKtbUA/s1600/what-is-javascript.png" title="What is JavaScript?" /></a></div>
<br />
JavaScript is a conservative, item based scripting language for Web pages. JavaScript code installed into your HTML pages can improve them with numerous fascinating components, from swapping pictures when you move a cursor over them, to multi-level drop-down menus.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
You can make truly advanced and practically application-like pages with the assistance of JavaScript. You needn't bother with any extraordinary programming other than a content manager and a Web program, and you needn't bother with access to a Web server. You can make and test all your JavaScript code right all alone PC.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<b>The downsides of JavaScript</b></div>
<div style="text-align: justify;">
At this time the most concerning issue is the blemished JavaScript usage that today's programs offer. Though all real programs that are form 3.0 or higher incorporate JavaScript support, they manage JavaScript in an unexpected way.</div>
<div style="text-align: justify;">
Indeed, distinctive adaptations of the same program handle JavaScript in an unexpected way. This makes it hard to make a convoluted JavaScript code that work over all programs. So dependably check your pages on whatever number diverse programs (and even stages) as could be expected under the circumstances.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<b>What do JavaScript code resemble? </b></div>
<div style="text-align: justify;">
Like HTML, JavaScript is just content that can be written into a word processor. Its code is installed in HTML inside a <SCRIPT> tag. Some old programs don't comprehend this tag. To keep them from regarding your JavaScript as HTML, dependably utilize this trap including HTML remarks.<br />
<br />
Therefore<br />
<ol>
<li>JavaScript is a lightweight, translated programming language.</li>
<li>Open and cross-platform.</li>
<li>Intended for making system driven applications.</li>
<li>Reciprocal to and coordinated with Java.</li>
</ol>
<div>
<b>JavaScript Syntax</b></div>
<br />
<div>
A JavaScript consists of JavaScript statements that are placed within the <script>... </script></div>
<div>
<div>
HTML tags in a web page.</div>
<div>
You can place the <script> tag containing your JavaScript anywhere within you web page but it</div>
<div>
is preferred way to keep it within the <head> tags.</div>
<div>
The <script> tag alert the browser program to begin interpreting all the text between these</div>
<div>
tags as a script. So simple syntax of your JavaScript will be as follows</div>
</div>
<div>
<br /></div>
<div>
<div>
<pre class="_codebox"><script ...>
    JavaScript code
</script></pre>
</div>
<br />
The script label takes two imperative attributes:<br />
<ol>
<li>Language: This property indicates what scripting dialect you are utilizing. Commonly, its quality will be javascript. Albeit late forms of HTML (and XHTML, its successor) have eliminated the utilization of this trait.</li>
<li>Type: This language is what is currently prescribed to show the scripting language in use and its esteem ought to be set to "text/javascript"</li>
</ol>
<div>
Therefore finally our above script become<br />
<br /></div>
<div>
<pre class="_codebox"><script language="javascript" type="text/javascript">
    JavaScript code
</script></pre>
<br /></div>
<div>
A simple example of JavaScript is:<br />
<br />
<pre class="_codebox"><html>
    <body>
        <script language="javascript" type="text/javascript">
        
        </script>
    </body>
</html>
</pre>
<br />
Output:<br />
<br />
Hello World!</div>

<br />
JQuery is a JavaScript framework by using JQuery our program become more easiest and more effective. JQuery simplifies the use of JavaScript.<br />
JQuery is not a language it is handwritten library file using JavaScript code. JQuery is a fast and featured rich JavaScript library that simplifies the HTML documents event handling, traversing, animating and Ajax interaction for fast, smooth and rapid web development.<br />
<br />
JQyery JavaScript library written by John Resig in 2006. The moto of using JQuery in web development is <b>Write less, Do more.</b><br />
<b><br /></b>
JQuery has several features some of them as follow<br />
<br />
<ol style="text-align: left;">
<li><b>DOM Manipulation:</b> Using JQuery it become very easy to manipulate DOM Object.</li>
<li><b>Event Handling:</b> JQuery offer a good feature of Event Handling. It has wide range of events which make web development more interactive. </li>
<li><b>Ajax Support:</b> JQuery suport Ajax which means we can develop or create a responsive and feature-rich site easily via using Ajax Technology.</li>
<li><b>Animation:</b> JQuery provide very innovative animation for our web site.</li>
<li><b>Light-Weight:</b> As we know that JQuery is JavaScript Library file hence it is very small in size. The size of JQuery library file is near about 19KB. JQuery comes along with Zipped and Minified.</li>
<li><b>Latest Technologies:</b> JQuery library use latest technologies like CSS3 selectors, HTML5  and basic XPath syntax.</li>
</ol>
<div>
<b><u>HOW to use JQury?</u></b></div>
<div>
<b><br /></b></div>
<div>
The question is arise is that how we use JQuery in our web development ?</div>
<div>
So using JQuery in our web development is very simple. We can use JQuery in our project in two ways.</div>
<div>
<ol style="text-align: left;">
<li>Local Installation.</li>
<li>CDN Based Version.</li>
</ol>
<div>
<b>Local Installation:</b> We can download JQuery Library file in our system and include it in our HTML file.</div>
</div>
<div>
If you want to download the JQuery latest version just click on the given link</div>
<div>
Download JQuery Library File : <a href="https://jquery.com/download/" target="_blank">https://jquery.com/download/</a></div>
<div>
<br /></div>
<div>
After downloading the library file follow the following steps</div>
<div>
<ol style="text-align: left;">
<li>Copy the JQuery Library that is <b style="background-color: white; box-sizing: border-box; font-family: 'Open Sans', Arial, sans-serif; font-size: 14px; line-height: 24px; text-align: justify;">jquery-2.1.3.min.js</b> file which you have downloaded and paste it into your project folder '/jquery' if there is no any folder like 'jquery ' you can create the folder and rename it to jquery.</li>
<li>After step one completed just open the html file in which you want to use JQuery features. </li>
</ol>
<div>
For Example:</div>
<pre class="html" name="code"><html>
    <head>
        <title>A simple JQuery example</title>
        <script type="text/javascript" src="/jquery/jquery-2.1.3.min.js"></script>
        <script type="text/javascript">
            $(document).ready(function(){
                document.write("Hello, World.");
            });
        </script>
    </head>
    <body>
        <h1>Hello</h1>
    </body>
</html>
</pre>
</div>
<div>
<br />
<b>Output:</b><br />
<br />
Above code will produce following result<br />
Hello, World.<br />
<br />
<b>CDN (Content Directory Network) Based Version:</b> Using CDN approach we include the JQuery library file directly from the CDN (Content Directory Network). <br />
Google and Microsoft provides the CDN Technique of latest version.<br />
<br />
For Example:<br />
<br />
<pre class="html" name="code"><html>
    <head>
        <title>A simple JQuery example</title>
        <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
        <script type="text/javascript">
            $(document).ready(function(){
                document.write("Hello, World.");
            });
        </script>
    </head>
    <body>
        <h1>Hello</h1>
    </body>
</html></pre>
<br />
<b>Output: </b><br />
<br />
Above code will produce following result<br />
Hello, World.
<br />
<br />
<br /></div>
<div>
</div>
</div>
