Program 5- Write a program to enter unit price and quantity and print gross bill amount,net bill amount and discount. (Discount=5%)

<html>
<body>
<h1>Program 5</h1>
<script>
var p=10 ;
var q=100;

document.write(“Gross Bill Amount=”+gba);
document.write(“<br>Discount=”+dis);
document.write(“<br>Net Bill Amount=”+nba);
</script>
</body>
</html>

Output

Now, here we completed the program where we provide the values in a program. In the next we will see Values enter at run time.

Program-6

<html>
<script>
var a1=parseInt(prompt(“Enter the value of a1 for addition”));
var b1=parseInt(prompt(“Enter the value of b1 for addition”));
var a2=parseInt(prompt(“Enter the value of a2 for subtraction”));
var b2=parseInt(prompt(“Enter the value of b2 for subtraction”));
var a3=parseInt(prompt(“Enter the value of a3 for multiplication”));
var b3=parseInt(prompt(“Enter the value of b3 for multiplication”));
var a4=parseInt(prompt(“Enter the value of a4 for multiplication”));
var b4=parseInt(prompt(“Enter the value of b4 for multiplication”));
c=a1+b1;
d=a2-b2;
e=a3*b3;
f=a4/b4;
document.write(“Addition=”+c);
document.write(“<br>Subtraction=”+d);
document.write(“<br>Multiplication=”+e);
document.write(“<br>Division=”+f);
</script>
