WEEKLY REFLECTION 2

-seperti biase,kami diberi rehat selama 1 jam.

 -selepas rehat,kami belajar Chapter 2 C++ Programming Language.

-  belajar c++ basics iaitu c++ language,datatype n c++ program.

-selepas itu, PN.Ayuni memberi latihan kepada kami. 

- Kemudian telah memberikan tugasan secara group iaitu Sum and Minus Two Integers.

CHAPTER 2  C ++ BASICS

2.1 C++ LANGUANGE

-         The C ++ language consists of the to two basic elements :

a)     Semantics

b)    Syntax

-         Semantics is a vocabulary of commands that humans can understand and that can converted into machine language.

-         Syntax is a language structure (or grammar ) that allows humans to combine these C++ commands into a program that actually does something.

1-    Data Type

Int Integer            - real 0-9

Float  float            }-decimal

Double double

Const  constant      - formula akan menjadi static

Char     character   -  one alphabet only a-z / z-a

String   string   - one or more word

2-    Input

Output/display – cout << please enter your =  ;

                             Radius

              Input – cin >> radius ;

3-    Output                             ∕ Variable name

Cout << “area =  “ << area ;

In body variable ;

To declare variable        /  semikolom

Data type variable_name ;

2.2 C++ PROGRAM

-         C++ program is a text file containing a sequence of C++ commands put together a according to the laws of C++ grammas.

KEY ITEMS	EXPLANATION
C++ Command	The building blocks of the C++ program.
C++ Grammar	A correct and valid C++ language construct, structure or rules.
C++ Program	A text file containing a sequence of C++ Command that does something.
C++ Source file	A text file that carries the extension. CPP.
Editor	A software tool to create and modify text files.
Compiler	A program that translates a C++ Program into a machine-language program that the computer can directly understand and executes.
Machine Executable File	A program that the computer can directly understand executes.
IDE         (Integrated Development Environment )	A software development tool that combines the compiler and the editor into a single package. It provides the windows, editors and controls for editing, compiling and debugging the code
