Declare an array of variable length in C language A lot of people keep asking about an array of variable length.Then they find a more often answer in the books, on the net i.e. use dynamic memory allocation.Though it is very important concept because it uses the memory in run time which reduces the execution time of your program but so many people are not used to this method which makes them fuzzy.I know another method to declare an array of variable length which is very comfortable to use.

HTML Form Attributes In the last post we discussed about the html forms, types of forms and show you how to create a simple form.Though form creation is an important step but forms are useless until they send the entered information to a specific location.In this post, we'll discuss the form attributes which determine the action performed by the form. The two main and most important attributes of a <form> tag are "action=" and "method=".Lets discuss each of these two.

HTML Forms HTML is a web page markup language which designs your static web pages.The most common thing we see in a web page is a form.We normally signup for various services, comments on articles, discussion forum, polls and many other services.These all are a type of form which one can easily create using the HTML "form" tag.HTML forms are used to collect different kinds of user input. A form is an area that can contain form elements. Form elements are elements that allow the user to enter information in a form (like text fields, text area fields, drop-down menus, radio buttons, check boxes, and so on). But HTML forms are only static.Means they can send the information but can't check whether the information is valid or not. To implement the form validation, you'll have to use a scripting language such as javascript, vbscript, php etc.Form validation is an important thing but form structure is another important thing which we can do using HTML only.
