A structure is user defined data type which is used to store record based data. Structure is useful when there is a need to process record type data for example student record which is a combination of more than variable (roll,name,class,marks etc). Structure encapsulates more than one variable into a single logical unit. Without structure, processing of record based data is not an easy task. Programmer need to declare many variables with different name. Which increase complexity?

Solution :
x + x3 / 3! + x5/ 5! + …
To a given accuracy for x from 00 to 1800 in the steps of 100, use a inbuilt function FACT(n) to compute the factorial.
Solution :
#include<stdio.h>
#include<conio.h>
int fact(int);
void main()

Thread
A thread is a basic unit of CPU utilization; it comprises a thread ID, a program counter, a register set, and a stack. It shares with other threads belonging to the same process its code section, data section, and other operating-system resources, such as open files and signals. A traditional (or heavyweight) process has a single thread of control.
Application
Many software packages that run on modern desktop PCs are multithreaded. An application typically is implemented as a separate process with several threads of control.

Java Script Date Operation
Convert dd/mm/yyyy date to yyyy/mm/dd
Java Script support date in many format except dd/mm/yyyy . So if you are working on a project which has date as in dd/mm/yyyy format then you will need to change it mm/dd/yyyy for further date related operations.
Following code will change dd/mm/yyyy date to mm/dd/yyyy date format

Jquery Animated Validation
Validation is most important part any website while creating a form. There are lots of methods and processes of JavaScript or jquery.
I have implemented basic validation as simple as possible which
can be used for empty fields check. You need to call just little function and
achieved validation on various HTML form tags.
Code
