Example: -X("-" is operator and "x" is a operand)

Binary operator is one operator and two operand

Example: x+y("+ "is operator and "x,y" is a operand)

Terinary operator is two operators and three operands

Example: (a>b)?a:b;("?,:" are operator and (a>b),a,b are operands)

Standalone application and Web application

Standalone application and Web application

Standalone application

• In Standalone application the networks is not applicable

• Command prompt is required like DOS console

• Creation, compilation, execution and output all are completed on a single system only

• Program executed starts from main function onwards

Example:- C,C++

Web application

• In web application networks is complusory

• Web browser is required like IE(Internet Explorer )

• In web applications creation compilation is on server side and execution and output both are done by client side

• Program execution Starts from int() function onwords

Example:- JAVA, .NET

• The application which is executed inside the web browser such applications are called as web application

• Web applications are also called as internet applications /modern applications

• web applications are GUI applications they are involving by 2 technologies

               Front end technologies
               Back end technologies

Front end technologies

>  These applications are used to take the input from the user as well as display the output

>The system which is used to take the input from the user, such system are called as client systems

Examples- HTML,JAVA,.NET,VB(Visual Basic)

Back end technologies

>These applications are used to store the DATA / Maniculating the data

>Generally these systems are called as server system

A server system is used for receiving the request and sending the response 

Example - ORACLE,MYSQL etc.....

Difference between C++ and JAVA

Difference between C++ and JAVA

C++

• Platform dependent

• Partial OOP(Object Oriented Language)/In complete

• Pointers supported

• Multiple inheritance supported by C++

• Clear Data type takes one byte of memory

• Operator over loading is supported by C++

• Friend functions are supported by C++

• It is a partial oop language where a program can able to write with class and with out class

JAVA

• Platform Independent

• Totally OOP(Object Oriented Language)/ FULLY

• Inbuilt pointer are supported by JVM(or) pointers in JAVA

• No multiple inheritance in JAVA directly

• JAVA char Data type takes 2 bytes of memory

• JAVA is not supporting operator overloading

• No friend functions in JAVA

• JAVA is a total oop language where every program must be writing inside the class only

About Programming langauage

About Programming Langauage

Every language is depending two conditions.They are

1.Syntax --> Syntax always concentrating on grammar rules

2.Semantics--> Its is always concentrating on meaning of the Statement

----Programming language main benefit is communication with the sytstem

Programming language are available in 3 levels.They are

1.Low level language ----------------first generation


Example is BINARY LANGUAGE (Instruction format example 1100100101)

->Symbolic Language

using symbolic language animal language communication is possible

->Natural language

Natural language is used for maintain the communication between person to person
