What is a Browser?

A browser is a computer program that resides on your computer enabling you to use

the computer to view WWW documents and access the Internet taking advantage of

text formatting, hypertext links, images, sounds, motion, blogs, and other features.

Firefox and Internet Explorer are currently the leading "graphical browsers" in the

world (meaning they facilitate the viewing of graphics such as images and video

and more). There are other browsers (e.g., Mozilla, Safari, Opera). Most offer many

of the same features and can be successfully used to retrieve documents and activate

many kinds of programs.

Browsers all rely on "plug-ins" to handle the fancier files you find on the Web.

Plug-ins is sub-programs stored within a browser or elsewhere in your computer

especially to support special types of files you may click on. If you click on a link,

and your computer does not currently have the plug-in needed for the file you

clicked on, you are usually prompted with an opportunity to get the plug-in. Most

plug-ins is free and easy and safe to install on your computer; follow the

instructions you are given.

The main way in which browsers differ is in the convenience features they offer for

navigating and managing the Web and all the URLs you may want to keep track of.

Netscape and Internet Explorer both offer the ability to e-mail documents,

download them to diskette, print them, and keep track of where you've been and

sites you want to "bookmark" or "Add to Favourites" (Microsoft's name bookmarks).

a) Save the document as browser.

OBJECTIVES

To learn the concept of Structure in C.

OUTCOMES

After completing this, students would be able to use the concept of Structure in the real life applications.

1# Write an interactive program in C to store the record of the N

students of a class and print them. The record consists of Name,

Class, Roll No, Enrolment, Marks.

2# Write an interactive program in C to store the record of the N

students of a class and arrange them rank wise. The record

consists of Name, Roll no, Marks.

3# Write a C program to add two distances entered by user.

Measurement of distance should be in inch and feet. (Note: 12

inches = 1 foot). Use the concept of structure.

4# Write a Program to accept five records of employee .The

Structure is:

struct

{

char name[25];

int age ;

int Basic;

}

Calculate the total salary of employees as:

Total Salary = Basic + DA + HRA

DA = 10% of Basic

HRA = 5% of Basic

Display the name, age and total salary of the employees in

descending order on the basis of total salary?

OBJECTIVES

To learn the concept of sub programming in C. To learn the concept of recursion.

OUTCOMES

After completing this, students would be able to write user define function and call them at different places.

Student would be able to write recursive program rather than iterative program.

Student would be able to distinguish between recursive approach and iterative approach for writing C program.

1# Write a function that calculates the compounded interest amount

for a given initial amount, interest rate & no. of years. The

interest is compounded annually. The return value will be the

interest amount. Use the following function definition: float

comp_int_calc(float int_amt, float rate, int years); Write a

program that will accept the initial amount, interest rate & the no.

of years and call the function with these values to find out the

interest amount and display the returned value.

2# Write a user defined function swap() in C to exchange the values

of two variable with using third variable and also without using

third variable. (use the concept of call be value and call by

reference).

3# Write a program to find the factorial of a given no using

recursion.

1# Write a program in C to print the Fibonacci series upto N terms

using recursion.

2# Write a function that returns the minimum and the maximum

value in an array of integers. Inputs to the function are the array

of integers, an integer variable containing the length of the array

and pointers to integer variables that will contain the minimum

and the maximum values. The function prototype is:

void minmax( int array[], int length, int * min, int * max);

array and its size, and returns the number of even numbers in the

array.

2# Write a function contains (char*, char) which returns true if the

1st parameter contains the 2nd parameter or false otherwise.

3# Write a program to compute sum of the array elements using

pointers.
