How To Make a Text Subscript or Superscript Using HTML Code

To make a text superscript or subscript in a webpage using HTML language, there are two tags provided in the language.

Superscript

To make a text or some characters superscript, the HTML tag is used. For example, suppose we have to display 2ⁿ⁺¹. To display it, we have to use the following code:

2n+1

We have to enclose the characters to be made superscript in  and 

Binary to Gray Code Converter

This post is to teach you how to convert binary number to corresponding Gray code. The conversion is so simple. You can see it..

If an n bit binary number is represented by B_n B_n-1 ...B₁ and its Gray code equivalent by G_n G_n-1...G₁ where B_n and G_n are the most significant bits (MSBs), then the Gray code bits are obtained from the binary code as follows. The symbol ⊕ stands for the Exclusive OR (XOR) operation explained below.

The conversion procedure is as follows:

String Comparison in C and C++ Languages and Working of strcmp function

In both C and C++ programming languages, an inbuilt function strcmp() is used to compare two strings. This function is defined in string.h header file. So, to use this function, you have to include the header file string.h in the program. Most of the people ( i mean beginners) have a wrong idea about the working of the this function. I also had made some false assumptions. This function takes two strings as arguments. And it compares the two strings using the ASCII equivalent of each character. Some of the false ideas about this function are:

The function returns 1 when the strings are equal and 0 when they are not equal
The function returns 1 when they are not equal
The function returns 1 when the first string is greater than the second and returns -1 when the first one is less than the second one

The ASCII Character Set or ASCII Chart

ASCII stands for American Standard Code for Information Interchange. ASCII is a 7 bit alphanumeric code used in computers. Each character is assigned with a positive integer (in between 0 and 127). This is the most popular coding system. The following is the ASCII chart of characters and corresponding integer value.

How to Hard Reset Nokia E63

This post will teach you how to hard reset Nokia E63, symbian smartphone. The same method can be

applied to hard reset similar E series phones, some other symbian phones and even some of the new Java phones from Nokia. Hard resetting is complete cleansing of phone memory and the firmware will repaired/reinstalled.

So when you hard reset your phone, it will result in loss of data including your contacts in phone memory and whatever you have stored in phone memory. To avoid loss of any important data, your can back up your data onto your memory card. There is an option provided in the phone to backup all the phone memory to memory card. To know how to backup your data, watch this video: http://www.youtube.com/watch?v=yPpqwhU4ErM

To hard reset your phone, Follow these instructions:

Nokia 603 Symbian

Nokia 603 is a symbian Belle full touch smartphone. Hard resetting may solve most of the problems with its software. I have reset one to solve a problem with the phone software and the problem was successfully solved. The problem was that when a link in any messages or notes are clicked, an error was shown and the web browser cannot be loaded. This was solved by hard resetting the phone using the three button combination.

C and C++ Programs for String Sorting

Here i am writing programs in c and c++ languages to sort a given number of strings. Sorting is carried out based on the ASCII values of the letters in the strings. The string comparing function strcmp() is used in the program. These programs sort a given set of strings in ascending order.To change it into descending order just replace > with < in comparison line. The comparison line in the code is marked by comment.

C Program:

#include<stdio.h>
#include<string.h>
#include<conio.h>
void main()
{
