C is a general-purpose, procedural programming language developed in the 1970s by Dennis Ritchie at Bell Labs. It was originally intended for writing system software like operating systems. Some key uses of C include creating computer applications, embedded software, firmware, compilers, and implementing operating systems. C is processor-oriented and has a large standard library, making it relatively easy to learn and allowing for fast compilation. However, C lacks features like runtime type checking, exception handling, and memory management, which can make programs error-prone.

C

5. DEVELOPED IN 1970’S BY DENNIS M .
RITCHIE
DEVELOPED FROM “B” LANGUAGE .
WRITTEN DOWN BY KERNIGHAN & RITCHIE IN
CLASSIC BOOK-
“THE C PROGRAMMING LANGUAGE ”
IN 1988 FINAL STANDARD “ANSI C”WAS
DELIVERED
LATER ADOPTED BY “ISO”.

6. COMPILATION AND EXECUTION OF SOURCE
CODE
PROCESS OF EXECUTION OF
PROGRAM
STEP 1. SAVE THE SOURCE CODE WITH
EXTENTION “.C”
FILE SAVE FILE
NAME
ABC.C
OK

7. STEP 2. COMPILE THE SOURCE CODE.
COMPILE OR ALT + F 9
STEP 3. EXECUTE THE MACHINE CODE
RUN OR CTRL + F 9
STEP 4. DISPLAY THE RESULT ON SCREEN.
ALT + F5

WRITING EMBEDDED SOFTWARES.
FIRMWARE FOR VARIOUS ELECTRONIC,

DEVELOPING VERIFICATION SOFTWARE, TEST CODE
AND SIMULATORS.
CREATING COMPILERS .
IMPLEMENT DIFFERENT O.S OPERATION.

16. PROCESSOR ORIENTED LANGUAGE -
SO IT IS EASY TO LEARN,AS IT FOLLOW ALGORITHM
TO EXECUTE.
LOTS OF LIBRARIES –
LARGE NO. OF PRE-DEFINED
FUNCTIONS.
SPEED OF COMPILATION-
IT PRODUCES MACHINE CODE FASTER
THAN OTHER LANGUAGE COMPILERS.

17. EASY TO LEARN-
ITS SYTYNAX IS VERY EASY TO UNDERSTAND.
PORTABLE-
ITS IDE’s SETUP IS SMALL(3-5MB), AND EASY
TO INSTALL.

19. RUN TIME TYPE. CHECKING IS NOT AVAILABLE
OOP’s FEATURES ARE NOT AVAILABALE LIKE
CONSTRUCTOR & DESTRUCTOR.
NO STRICT TYPE CHECKING.
DOES NOT SUPPORT EXCEPTION HANDLING.
IT REQUIRES YOU TO DEFINE SOMETHING
BEFORE YOU USE IT.

20. DISADVANTAGES

ERROR PRONE.
AS THE PROGRAM EXTENDS IT
IS VERY DIFFICULT TO FIX BUGS.
