SOFTWARE DEVELOPMENT LIFE CYCLE  MODELS A software process model is simplified representation of software process. 1)WATERFALL MODEL 2)V-MODEL 3)ITERATIVE MODEL 4)RAD MODEL 5)SPIRAL MODEL 6)BIG BANG MODEL WATERFALL MODEL: *It  is used when requirements are clear and accurate documents when system is to be produced. *Waterfall  Model is the simplest model of  software development part.                         Waterfall Model - Application Every software developed is different and requires a suitable SDLC approach to be followed based on the internal and external factors. Some situations where the use of Waterfall model is most appropriate are − Requirements are very well documented, clear and fixed. Product definition is stable. Technology is understood and is not dynamic. Waterfall Model - Advantages Some of the major advantages of the Waterfall Model are as follows − * Simple and easy to understand and use * Easy to manage due to the rigidity of the model. Each phase has specific

OPERATORS IN C LANGUAGE

                               OPERATORS IN C  An operator is a symbol that tells the compiler to perform specific mathematical or logical functions.  C language is rich in built-in operators Arithmetic Operators Relational Operators Logical Operators Bitwise Operators Assignment Operators Additional Operators Arithmetic Operators: Basic Arithmetic operators include Operator Description                                              Example + Adds two operands.                                      A + B = 30 − Subtracts second operand from the first.       A − B = -10 * Multiplies both operands.                                A * B = 200 / Divides numerator by de-numerator.                  B / A = 2 % Modulus Operator(Returns remainder of a division)   B % A = 0             ++ Increment operator increases the integer value by one. A++ = 11 -- Decrement operator decreases the integer value by one.  A-- = 9 Relational Operators : Operator Function ==        Che
