oop = object oriented programming

Machine language use 1 and 0, it’s called assembly

C language is a moderate level of language

 

Encapsulation: private/public

Inherited: sunah

Abstract: wajib/sunah or we may called pansy (banci)

Interface: wajib

Polymorphism: ?

 

Blue Print is like a sketch

 

twitter.com use NoSQL (monggodibi) as its database and it use java language, or ruby, etc.

 

History of Algorithm:

Founder -> Al-Khwarizmi

 

Definition of Algorithm:

-Set a Sequential Instructions developed to describe important processes in producing an Output with specific required Input is given.

 

Flow Chart:

 

Flow Chart Definition:

-Shows logic of an algorithm

-Emphasizes individual steps and their interconnections

-e.g. control flow from one action to the next.

 

Sequence:
-Sequence is series of consecutive commands/statements

 

Pseudo Code:

Definition of Pseudo Code:

-An artificial and informal language that helps you develop algorithms

-Pseudo Code is similar to human language, convenient, and user friendly.

Basic Computer Operation an Pseudo Code:

1) Input

2) Output

3) Compute

4) Storing Value to an Identifier (Store)

5) Compare

6) Repetition (Loop)

 

History of C
Founder: Martin Richard

 

Why Using C:

-Flexibility

-Portability

-A Well Known Programming Language

-Supported With a Large Number of Libraries

 

C Structure :

1)

main ()

{

statements;

}

2)

main ()

{

statements;

return (0);

}

3)

void main ()

{

statements;

}

4)

int main ()

{

statements;

return (0);

}

 

Escape Sequences:

> \a     = bell, alert, system beep

> \b     = back space

> \t      = horizontal tab

> \n     = new line, line feed

> \v     = vertical tab

> \r      = carriage return

> \’       = single quote

> \”      = double quote

> \\      = backslash

> \xdd = hexadecimal notation

> \ddd = octal notation

 

Data Type:

>In C, there are 5 data types and 4 modifiers.

Data Types:

-Character                       = char

-Integer                            = int

-Floating Point               = float

-Double Floating Point = double

-Void                                 = void

Modifiers:

-signed

-unsigned

-long

-short

 

Keywords:

-Keywords/reserved words are words that have special meaning to the C compiler

Example:

-auto                 -double           -int                -struct

-break               -else                -long             -switch

-case                  -enum             -register       -typedef

-char                  -extern           -return          -union

-const                -float               -short            -unsigned

-continue          -for                  -signed         -void

-default             -goto                -sizeof           -volatile

-do                     -if                     -static            -while
