6. Create a webpage to convert a given text from uppercase to lowercase using JavaScript.

<HTML>

<HEAD>

<STYLE Type="text/css">

input { height:25px; width:100px; color:blue}

th { text-align:left;}

</STYLE>

<SCRIPT Language="JavaScript">

function Convert()

{

if(( document.forms[0].elements[0].value != "" ) &&

document.forms[0].elements[0].value !=

document.forms[0].elements[0].value.toLowerCase() )

{

document.forms[0].elements[1].value =

document.forms[0].elements[0].value.toLowerCase();

}

else

alert("Enter Text in UPPERCASE!");

}

</SCRIPT></HEAD>

<BODY TEXT=blue BGCOLOR=BEIGE SIZE=22>

<CENTER>

<H3>CONVERSION OF TEXT FROM UPPERCASE TO LOWERCASE</H3>

<FORM>

<TABLE bgcolor=gray>

<TR><TH>Enter Text in UpperCase</TH>

<TH><INPUT TYPE="text" NAME="upper" value="" SIZE=10></TH></TR>

<TR><TH>Text in LowerCase</TH>

<TH><INPUT TYPE="text" DISABLED NAME="lower" value="" SIZE=10></TH></TR>

<TABLE>

<br>

<INPUT TYPE="button" onClick="Convert()" value="CONVERT">

<INPUT TYPE="reset" value="RESET">

</FORM> </CENTER> </BODY> </HTML>

5. Create a webpage with two textboxes and command buttons to perform arithmetic operations and display the result in appropriate dialog boxes using JavaScript.

<html>

<head>

<title>Arithmetic Operations</title>

<style type="text/css">

input { height:25px; width:100px; color:blue}

th { text-align:left;}

</style>

</head>

<body bgcolor=beige text=blue>

<center>

<h1> <u>ARITHMETIC OPERATIONS</u></h1>

<form>

<table bgcolor=gray>

<tr><th>Enter 1st Number</th><th><input type="text" size=10 name=text1></th><tr>

<tr><th>Enter 2nd Number</th><th><input type="text" size=10 name=text2></th><tr>

</table><br>

<input type=button value="ADD" onClick="add()">

<input type=button value="SUBTRACT" onClick="sub()"><br>

<input type=button value="MULTIPLY" onClick="multiply()">

<input type=button value="DIVIDE" onClick="divide()"><br>

</form>

<script language="JavaScript">

function add()

{

var result = eval(document.forms[0].elements[0].value) + eval(document.forms[0].elements[1].value);

alert("SUM = " + result);

}

function sub()

{

var result = eval(document.forms[0].elements[0].value) - eval(document.forms[0].elements[1].value);

alert("DIFFERENCE = " + result);

}

function multiply()

{

var result = eval(document.forms[0].elements[0].value) * eval(document.forms[0].elements[1].value);

alert("PRODUCT = " + result);

}

function divide()

{

var result = eval(document.forms[0].elements[0].value) / eval(document.forms[0].elements[1].value);

alert("QUOTIENT = " + result);

}

</script>

</center>

</body>

</html>

4. Create a webpage to demonstrate the use of External Cascading Style Sheets.

Code for “mystyle.css”:

body{

background-color: orange;

font-family:serif;

color: blue;

font-size: 26pt;

}

h3{ color:blue; }

.M { color: Magenta; font-style:italic }

.Y { color:yellow; font-style:bold }

.R { color:Red; text-decoration:underline }

ul {

list-style-type: square;

}

Code for “ExternalCSS.html”:

<HTML>

<HEAD>

<TITLE>External CSS</TITLE>

<LINK REL="stylesheet" HREF="mystyle.css">

</HEAD>

<BODY>

<H3>Applying Styles using External Cascading Style

Sheets</H3>

<span class="M">This text is Italic and Magenta.</span><br>

<span class="Y">This text is Bold and Yellow.</span><br>

<span class="R">This text is underlined and Red.</span><br>

<P>This list is applied with External CSS:</P>

<ul>

<li>Element1

<li>Element2

</ul>

</BODY>

</HTML>

3. Create a webpage to display system date in the given format: Ex: 01 January 2016

<HTML>

<HEAD><TITLE> Display Date </TITLE>

<SCRIPT language="JavaScript">

var months = new Array(12);

months[0]= "January";

months[1]= "February";

months[2]= "March";

months[3]= "April";

months[4]= "May";

months[5]= "June";

months[6]= "July";

months[7]= "August";

months[8]= "September";

months[9]= "October";

months[10]= "November";

months[11]= "December";

function CustomDate(m_date)

{

var theday = m_date.getDate();

var themonth = months[m_date.getMonth()];

var theyear = m_date.getYear()+1900;

return theday + " " + themonth + " " + theyear;

}

</SCRIPT>

</HEAD>

<BODY bgcolor=beige text=green>

<center><font color=blue><H1>Webpage to Display System Date</H1></font></center>

<H1>Today is:</H1>

<font size=22 color=magenta>

<SCRIPT>

document.write(CustomDate( new Date()));

</SCRIPT>

</font>

</BODY>

</HTML>

void main()

{

int percent;

clrscr();

case 10:

case 9:

case 8:

case 7:printf("Distinction!\n");

break;

case 6:

printf("First Class!\n");

break;

case 5: printf("Second Class!\n");

break;

case 4: printf("Pass!\n");

break;

default:printf("Fail!\n"); break; } getch(); }

5. C Program to read numbers from keyboard continuously till the user presses 999 and find sum of positive numbers.

/*5. C Program to read numbers from keyboard continuously till the user presses 999 and find sum of positive numbers. */

#include<stdio.h>

void main()

{

int num, sum=0;

clrscr();

while(1)

{

printf("Enter any number:");

scanf("%d",&num);

if(num>0 && num!=999)

{

sum=sum+num;

}

if(num==999)

{

printf("Sum of Positive numbers=%d",sum);

getch();

exit(0);

}

getch();

}
