basic concept of cpp

 introduction of cpp.

·       Cpp programming language is developed by Bjarne stroustrup in the early 1980 at Bell Laboratories.

·       Cpp is one type of object oriented language.

·       It’s in used class is concept of structure these have first of all these called clss with c.

·       Cpp extent ion denoted improvement in c.

Give the basic concept of cpp. 

Object

·         To combine both data and function in single unite is called object

·         Object are basic runtime entities.

·         Syntax

   Class name  object name;

Class

·         Class is an expanded concept of data structure, it can hold both data and function.

·         Class classname.

Data abstraction

·         Classes use the concept of abstraction and are defined list of abstract attributes(data).

Data encapsulation

·         both data and function in single unit is called data encapsulation .

inheritance      

·         code reusability is called inheritance.

Polymorphism

·         ability to take more than one form is called polymorphism

dynamic binding

·         it is also called dad binding

·         it is run time polymorphism

message passing 

·         object communicate with each other by sending or receiving message. 

What is the disadvantages of c ?

·         In c not provide security

·         We not easily find out which data used by which function

·         Code length is more

·         Boolean data type not available.

·         Provide less functionality

·         Function have unrestricted access of global data

starting graphics with c or c++

before some time in c or c++ not support graphics it's in we only made simple dos base application 

    including graphics in c or c++ we made more flexible over application we also create animation using graphics. it's in BGI is contain some graphics driver . 

     tc have it's special screen resolution (1024*768). if over system's screen resolution not match with it's we can't able to create graphics appliction.

    you want to create application with graphics  below code is useful to your starting

basic sql information

SIMLE QUERY use in sql

spool g:/database/oracle/first  // save in given path

commit;//save outomatic

show pagesize;disply  pagesige

set pagesize (value);set pagesige

show linesige;show linsize

set linesize (value);set linesize

SELECT *FROM TAB;list of table

DESC tablename;Given structure

SELECT *FROM tablename; Information of define table

CQL++

·                Cql++  is editor

·                It have many user accesses all data at a time

·                Provide more  flexibility then sql

·                Database can be shared in efficient manner

DATA TYPE ->

1.           NUMBER

·                Used to store floating(real) or negative or positive value

·                Precisions can be up to 38 digit

2.           CHAR

·                Store character string or fix length

·                Maximum length is 255.

      3     VARCHAR

·                More flexible then character

·                Maximum length is 255

4                  VARCHAR2

·                it’s length is 2000

·                no default size will be consider

·                size must be specified

·                it is lover to accesses

5                  DATE

·                used to store date &time

·                standard format of   date is DD-MM-YY

6                  RAW

·                store binary type data

·                maximum size is up to 255 bytes

7                  LONG RAW

·                store large amount of binary type data

·                maximum length is up to 2 gb

SIMPLE SYNTEX USED IN SQL:

NEW CREATE TABLE-

CREATE TABLE tablename (columname1 datatype(size));

INSERT DATA/VLUES

INSERT INTO tablename values(‘&columname1’,’&columname2’);

View data in table

ALL ROW AND ALL COLOUM

SELECT *FROM tablename;

SELECTED COLOUM & ALL ROW

SELECT coloumname1,coloumname2 FROM tablename;

SELECTED ROW&ALL COLOUM

SELECT *FROM tablename WHERE condition;

SELECTED COLOUM&SELECTD ROW

SELECT coloumname1,coloumname2 FROM tablename WHERE condition;

UPDATE ROW/

UPDATE tablename SET coloumname= expretion WHERE condition;

MODIFY TABLE(coloum)

ALTERTABLE tablename MODIFY (coloumname newdatatype(size));

DROP COLOUM

ALTERTABLE tablenme DROPCOLOUM coloumname;

ADDNEW COLOUM

ALTERTABLE tablename ADD (coloumname datatype(size));

TRUNCATE &DELET

DROPTABLE tablename;

TRUNCATETABLE tablename;

DUPLICATE NOT SHOW

SELECT DISTINC coloumnme  FROM tablename;

ASCENDING/DESCENDING

SELECT *FROM tablename ORDER BY coloumname(order);//desc  --asce

DELETE PERTICULAR ROW

DELETE FROM tablename WHERE condition;

CREATE TABLE FROM ANOTHER TABLE

CREATE TABLE newtablename (coloumnamename1,coloumnname2)AS SELECT coloumnname1,coloumnname2 FROM oldtablename WHERE condition;    // where condition is use particular row have

INSERTING DATA INTO TABLE FROM ANOTHER TABLE

INSERT INTO newtablename (coloumname1,coloummname2) SELECT  coloumname1,coloumname2 FROM oldtablename WHERE condition;

problem of system crash

when problem of System crash

v     See first what is problem

v     First open in normal mode

                    See what is error report

                    If your pc automatic shutdown you can’t see error message
