Java Program to Find Union of two Arrays
For example we have two sorted arrays a1[]={2,3,5,11} and a2[]={4,7,9} then union of a1 and a2 will be {2,3,4,5,7,9,11}. A Java program for finding union of two arrays is given below.

Valentine’s Day Special C Program to Print Heart Shape with Happy Valentine’s Day Message inside it
Today’s day is very special for all lovers. So I thought that I should share some programming stuff that show Valentine’s Day felling. A C++ program is given below which prints heart shape with a Happy Valentine’s Day message inside it. If you want, you can change the message by changing the value of string message. I hope that you will like this.
