C++ BASICS 
DATE : 2 FEB 2011 (WED)

C++  language consists of two basic elements :-

1. Semantics

2. Syntax

How to create the programming ?

compulsory symbol before starting to create the programming

#include <IDStream.h> //header
Main ( ) // start body
{ // Open curly braket
} // close curly braket
// comment hidden
/ * , * /

Declare variable

Data_type and variable_name

int = integer 0-9
float = float (decimal)
double = double (decimal)
char = character (a-z / A-Z)
string = string (sentences)
const = constant ( tidak berubah )

Rules:
---->Tengok formula
---->Cari ade bape variable name
---->Declare variable

Input:
Cout <<“----------------------” ;
Cin >>variable_name_that_had_declared;

WARNING : BE CAREFULL HURUF KECIL DAN BESAR

Output:
Cout <<“----------------------”<<
variable_name_that_had_declared;

EXAMPLE OF PROGRAMMING

Flow chart

start > read radius > area = 3.142 * radius * radius > print output

#include <iDStream.h>//header
Main( ) //start body
{ // Open curly braket
//declare variable
Float area;
Float radius;
// input 1
Cout <<“enter radius”;
Cin>> radius;
//formula
area = 3.142 *radius*radius
//output
Cout <<“answer”<<area ;
Return 0 ;
} // close curly bracket
//end bracket
