How to make tables using HTML code

In HTML (Hyper Text markup Language), <table> tag is used to create tables. Table is basically meant to represent data in tabular form. But people also use tables to design webpages, especially when they want to divide the web pages into some equal blocks. Now we will start with the basics of table tag. The table starts with a <table> tag and ends with the HTML tag </table>. Whatever comes in between <table> and </table> is either the data in the table or further HTML codes to design the table. These two tags help only to inform the starting and ending of the table.

Storage Classes for Variables in C Programming Language

Every variable in C programming language has two properties; type and storage class. 'Type' refers to the data type of the variable such as integer, character, floating point values etc. It also deals with the size of the variable ( in bytes). 'Storage class' determines the part of memory where storage is allocated for the variable and how long the storage allocation continues to exist. It also determines the scope which specifies the part of the program over which a variable name is visible, i.e. the variable is accessible by name. The scope restriction can be overrode by making use of pointers. Whatever, in short, storage class is the property that determines the part of memory where storage is allocated, the lifetime of variable and the scope of the variable.

There are for storage classes in C programming:

• Automatic
• Register
• External
• Static

How to Connect PC or Laptop to Internet Using Android Phone

The Android operating system supports usage of Android phones as an Internet modem for Personal computer or laptops. This facility of sharing the Internet connection of Android phone with a laptop or PC through a USB cable is called USB tethering. It supports most of major operating systems.

In Linux:

In Linux you just have to enable 'packet data' in phone first, connect phone with PC or laptop through USB data cable and check the option 'USB tethering' in Settings. It is somewhere within USB settings or Wifi and network settings. The place of this option may vary from phone to phone.In my phone (Ssmsung Galaxy S Advance, GT-I9070) , it is found as follows: Settings-> Wireless and Neetwork->Tethering and Portable Hotspot-> USB tethering. Check the option 'USB Tethering'. When 'USB tethering' is enabled, your Linux OS will automatically install the 'Remote NDIS based Internet sharing' driver. and your computer will automatically connect to internet within a few minutes.

How to Display Mathematical Symblos, Greek Letters etc in HTML

When i was writing a post, i found it difficult to display some mathematical symbols in the post. At last, i solved it and found that there are easy to remember mnemonics for most of the symbols we come across. Sometimes you can get them only from the 'charmap' (enter charmap in 'Run' in your windows OS). There are escape sequences in HTML which will help you to include mathematical symbols and other Greek letters which are often used as variables or notation for some processes. To display these symbols in a webpage, simple mnemonics or corresponding code can be used. These informations are directly available in HTML4.0 website.

Conditional Operator in C and C++

Conditional Operator is an operator which is substitutive for if-else statements. It is a ternary operator (operator which operates on 3 operands). It is often called ?: operator. The operands are expression1, expression2 and expression3. The syntax is as follows:

expression1 ? expression2 : expression3

The expression expression1  will be evaluated always. Execution of expression2 and expression3 depends on the outcome of expression1. expression1 is checked whether true or not. It is considered like a boolean variable. The outcome of an expression is true if it has a non zero value. If its value is zero, the outcome of expression is false. If the expression1 is true, then expression2 is evaluated. If the expression1 is false, then expression3 is evaluated. Consider the following example:

Binary Tree And Prefix & Postfix Notations Of Arithmetic Expressions

We can construct meaningful derivation trees that enable us to represent arithmetic expressions in infix, prefix and postfix forms. A binary tree is enough to represent all these three notations of arithmetic expressions. Both prefix and postfix notations are unintelligable for humans. But they are of great use in computer science. Compilers often convert infix to prefix notation and then to assembler code. From a derivation tree of an algebraic expression, we can get equivalent prefix and postfix notations. An algebraic expression in terms of operators and operands can be derived by an ambiguous context-free grammar. Prefix notation is the parenthesis-free notational scheme invented by Polish logician Jan Lukasiewicz and is often called polish notation. In prefix notation operators are followed by operands.

For example, in prefix notation A + B is written as +AB. Postfix notation is reverse of prefix notation. AB+ is  the equivalent postfix notation of A + B. The infix form is evaluated and the binary tree is created according to the priority of the operators. Let us start from the simplest examples.

Linear Search in C and C++ Languages

Linear search simply means 'looking for an element in the whole array from one end to the other'. The searched element is compared with the first element of array first, then with the second, then with the third, so on upto the end of the array. This is time consuming when the array is pretty enough. The time complexity is highest.The C and C++ programs for linear search is given below.

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 <sup> 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
