Programming C

what is machine language ?

Computer has made many logic gate such as other electronics device. bot it is working only two logic gate 0 and 1.It called also binary code.
Computer worked all of problem such as small, big, simple, complex by binary code.
We are counting 0,1,.....9 in decimal code and 0, 1 uses in binary code.Binary code uses 0, 1 in this two code called bit .
When computer discovered, then program write only 0 and 1 . We are knowing many language, but computer only understand 0 and 1 . That's called machine language.
But machine language write a program so defecult .A simple program are writing to need a lot of time .Simple two number addition (Supposed) :

   0000 0010 1011 0110 1010 (get i)
  0000 0101 1100 1100 1100 (get j)
   1000 0011 0011 1010 1100 (add i with j)
   1000 0011 1010 0011 1000 (store result)

So program is written very defecult by machine language.Others problem,Machine language program is not run to other computer.
Those program run by assembly :

 Load I
 Load J
 ADD I ADD J
 Store Result

But Computer operate by machine language.So you can write a program in assembly, you will be translate in machine language.
After 1950, Computer programming developed for all over the people.Then American Lady Dr. Gress Hooper developed by three language Math-matic, Flow-matic and A2.In 1957, IBM company's James Backer developed by FORTRAN Language and 1958 developed ALGOL and 1960 developed COBOL High Level language.After day by day developed BASIC, ADA, Pascal, C, C++, Java e.t.c. High level programming language facility that programmer has not know computer others experience .

All programming language is worked same type, but same data is not taken. There are various data take. In 1957 developed FORTRAN language. FORTRAN means FORmula TRANslation.It's uses only mathematical teams.
In 1960 developed COBOL language.COBOL means COmmon Bussiness Oriented Language.CoBOL used in made report, memo e.t.c .
FORTRAN and COBOL are used this people which are knowing those language.But It was not for all people or students.For this problem, They developed BASIC and Pascal language. BASIC means Beginners All-purpose Symbolic Instruction Code.
In 1960,At frist Durt Mouth Collage in United State used this language.

In 1970 professor Niclas Whorth developed Pascal language for essay learning programming language.Pascal is first modular programming language.Modular programming language means one program is divided by many others program.Pascal is first modular programming language, but it has many limited.
Man thinking that using programming language, it controlled I/O device, memory and others device
After C developed to controlled I/O device, memory and others device. C is developed for not only problem solved, it has many others problem solved.Programming language C is fulfill for library function.
Many others programming language developed in many place. Such as PROLOG,APL, PL/1,ADA, LISP, PILOT,Pert e.t.c .
