Operators in C Programming : Arithmetic Operators

By
There are five arithmetic operators in C. They are
Operators                               Purposes
     +                                         Addition
     -                                          Subtraction
     *                                         Multiplication
     /                                          Division
    %                                         remainder after integer division (also called modulus operator)

There is no exponential operator in C. However, there is a library function (pow) to carry out exponential.

The operands acted upon by arithmetic operators must represent numeric values. The remainder operator (%) requires that both operands be integers and the second operand be non zero. Similarly, the division operator (/) requires that the second operand be non-zero. Division of one integer quantity by another is referred to as integer division. The operation always result in a truncated quotient (i.e. the decimal portion of the quotient will be dropped). On the other hand, if a division operation is carried out with two floating-point numbers, or one floating point numbers and other integer, the result will be a floating point.

Database Management System(DBMS)

By
Data and Information  Data is an unprocessed raw fact which does  not give complete meaning about any object,person, entity etc. But when various inter-related data arranged in a row, it gives a complete meaning which is referred to as information.

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.

Answer: Manipulators are special functions that can be included in the I/O statement to alter the format parameters of a stream. Table-2 shows some important manipulator functions that are frequently used. To access these manipulators, the file < iomanip.h > should be included in program.                               Table-2               Manipulators                                                    Equivalent ios function               set...
