introduction to c programming language

introduction to c programming language

• 2.
   C isthe famous programming language designed to develop system application program.
• 3.
   It isknown as the starting of every programming language all the basics of a program language starts from C language.  C is known as general purpose procedural programming language.
• 4.
   Developed byM. Dennis Ritchie at the Bell laboratories in the year of 1972.  C is known as high level language because it has the power of a lower level language and easy syntax like high level language.
• 5.
   Easy tolearn  It’s a structured programming language
• 6.
   Can handlelow level programs  Compiled code can be used in different computers
• 7.
   C isa robust language  C is a highly portable language means once compiled; the code can be run in any computer.
• 8.
   Compiler isa computer program that transforms the human written language into machine level language.
• 9.
   In generalwords computer takes the code written by you and converts it into binary code.
• 10.
   #include<stdio.h> #include<conio.h> void Main() clrscr(); { Printf(“myfirst C program”); }
• 11.
   #- Prerocessorof program  Include-Include is a keyword
• 12.
   Stdio.h-Standard input/outputheader file  Conio.h-Console input/output header file
• 13.
   Void-is akeyword that collects the garbage value  Main()- main() identifies starting of the program execution
• 14.
   Clrscr()-To clearthe console screen  {, }-Group all statements together  Printf()-It is a function to print the output on screen.
• 15.
   Data typeof C language mostly divided into 5 major types  int, char, float, double, void
• 16.
  int char float voiddouble
• 17.
   Int –Usedto identify an integer value  Char- Used to identify a character  Float- Used to identify floating point type  Double- Used to identify floating point type  Void- denotes to type with garbage value
• 18.
   Variable isa stored data memory allocated to use it in future and we can change the value too.
• 19.
   Syntax- typevariable name;  Ex- int a, b, c;
• 20.
   Int-Data type A, b, c variables
• 21.
   Int-Data type A, b, c variables  ;-Identifies the end of statement.
• 22.
