Introduction to c programming,
- 2. COMPUTER IT IS AN ELECTRONIC DEVICE FOR MAKING CALCULATION AND CONTROLLING OPERATION THAT ARE EXPRESSIBLE IN NUMERICAL AND LOGICAL TERMS. Analytical Engine It was a mechanical machine. Jon Von-Neuman Binary Bit – 1 (0.5 v) , 0 (Null) 0-1,A-Z,a-z,special symbol(.,+-……)=256
- 3. ASSEMBLY LANGUAGE • ASCII ( AMERICAN STANDARD CODE FOR INFORMATION INTERCHANGE). • ANSI (AMERICAN NATION STANDARD INSTITUTE). • AT & T ( AMERICAN TELEPHONIC AND TELEGRAPHIC LABORATION). It works as a Translator Assembler Editor Linker Loader
- 4. HIGH LEVEL LANGUAGE B WAS THE FIRST HIGH LEVEL PROGRAMMING LANGUAGE. IT WAS DEVELOPED IN 1970. C LANGUAGE WAS IN 1972 IN AT & T LAB AT ANSI OF CALIFORNIA DEVELOPED BY DENNIS RITCHIE. EXAMPLE OF HIGH LEVEL LANGUAGE ARE COBOL,FORTRAN,BASIC,C AND C++. ADVANTAGES OF HIGH LEVEL LANGUAGE •FAST PROGRAM DEVELOPMENT. •TESTING AND DEBUGGING A PROGRAM IS EASIER THAN IN THE ASSEMBLY LANGUAGE. •PORTABILITY OF A PROGRAM FROM ONE MACHINE TO ANOTHER.
- 5. IT IS A HIGH LEVEL PROGRAMMING LANGUAGE. ALL THE SYNTAX OF C LANGUAGE IS WRITTEN IN THE SMALL ALPHABET LETTER. THE COMPILER OF C LANGUAGE IS KNOWN AS TURBO C2, BUT ITS CURRENT VERSION TURBO C3. C IS A HIGH LEVEL PROGRAMMING LANGUAGE AS WELL AS KNOWN AS MIDDLE LEVEL PROGRAMMING LANGUAGE. IT FOLLOWS TOP TO DOWN PROGRAMMING APPROACH. TURBO C2 INCLUDES LINKER , LOADER , EDITOR , COMPILER.
- 6. #include<stdio.h> void main() { printf(“hello world”); printf(“welcome to my first program”); getch(); } EXAMPLE
- 7. DESCRIPTION OF ABOVE EXAMPLES:- #include – PRE PROCESSOR DIRECTORY <stdio.h> - HEADER FILE printf – LIBRARY FUNCTION, USED TO PRINT THE MESSAGE ON THE OUTPUT SCREEN. TO SAVE – PRESS ALT+F THEN CLICK SAVE AS AND SAVE THE FILE AS FILENAME.C . .C – DOT C IS THE EXTENSION OF C PROGRAMS. TO COMPILE – ALT + F9 TO EXECUTE / RUN – ALT + F5 getch() – IT IS ALSO A LIBRARY FUNCTION USED TO HOLD THE OUTPUT SCREEN.
