Operators in C programming : Bitwise Operators

By
Bitwise Operator are used for manipulating data at bit level. These operators are used for testing the bits, or shifting them right or left. Bitwise

The most common used unary operator is unary minus, where a numerical constant, variable expression is preceded by a minus sign.
Unary minus operator is distinctly different from the arithmetic operator which denotes subtraction ( - ). The subtraction operator requires two separate operands.
Several examples of unary minus operator
-743                 - 0X7FFF                    -0.2                 -5E-8
-r00+1             - (x+y)                         -3 *(x+y)
In C, all numeric constants and variable are considered as positive. So, unary plus is not written as unary minus such as
+743 = 743
+(x+y) = x+y

What is Java Applets?

By
An applet is a special kind of Java program that is designed to be transmitted over the Internet and automatically executed by a Java-compatible web browser. Furthermore, an applet is downloaded on demand, without further interaction with the user. If the user clicks a link that contains an applet, the applet will be automatically downloaded and run in the browser. Applets are intended to be small programs. They are typically used to display data provided by the server, handle user input, or provide simple functions, such as a loan calculator, that execute locally, rather than on the server. In essence, the applet allows some functionality to be moved from the server to the client.
