C PROGRAMS WITH OUTPUT AND ITS EXPLANATIONS:

OK GUYS I KNOW WHAT ARE YOU THINKING. KEEPING ON LEARNING THEORY WILL BE BORED. SO LETS US START OUR PROGRAM.

NOW  I WILL TEACH YOU HOW TO PROGRAM AND ITS TECHNIQUES:

OK FIRST OPEN TURBO C SOFTWARE.

NOTE:

CODINGS ARE CASE SENSITIVE SO IF IT IS IN UPPER CASE IT WILL SHOW ERROR:

            SYNTAX OF C LANGUAGE:

                                                           #include<stdio.h>

#include<conio.h>

void main()

{

clrscr();

                       printf("HELLO WORLD\n");

getch();

}

                                      #

                           PREPROCESSORS.

                          include<stdio.h>

                         HEADER FILE.

                      VOID MAIN() 

                            NO RETURN TYPE, MAIN FUNCTION.

                        {

                       BODY OPEN/ OPEN PARANTHESIS.

                         CLRSCR();

                                PREDEFINED FUNCTION.

                      PRINTF("hello world");

                             PREDEFINED FUNCTION/ OUTPUT FUNCTION.

                       GETCH();

                             PREDEFINED FUNCTION.

                        }

                       BODY CLOSE/CLOSE PARANTHESIS.

                 

                                PROGRAM OUTPUT:

HELLO WORLD.

                          PROGRAM EXPLANATION:

             SO FIRST #include<stdio.h> IS AN HEADER FILE. STDIO STANDS FOR STANDARD INPUT AND OUTPUT.

             STDIO.H  IS A COLLECTION OF PREDEFINED FUNCTIONS/METHODS.

             IT IS ALSO CALLED AS THE LIBRARY OF "C".

             INCLUDE IS USED TO INCLUDE THE HEADER FILE INTO THE PROGRAM.

           #, IT IS CALLED PREPROCESSOR.

           IT INCLUDES THE LIBRARY OF C INTO THE PROGRAM BEFORE THE EXECUTION OF THE PROGRAM.

        CONIO, IT STANDS FOR CONSOLE INPUT AND OUTPUT.

         IT IS USED TO SHOW THE OUTPUT ON CONSOLE WINDOW.

          VOID IS A KEYWORD WHICH INDICATES THAT NO ONE VALUE IS BEING RETURNED BY THE FUNCTION.

           MAIN FUNCTION IS CALLED AS THE ENTRY POINT OF ANY PROGRAM.

            THE EXECUTION OF ANY PROGRAM STARTS FROM THE MAIN FUNCTION.

           CLRSCR ITS STANDS FOR CLEAR SCREEN.

            IT IS A PREDEFINED FUNCTION WHICH IS USED TO CLEAR THE OUTPUT SCREEN.

             IT ACTS LIKE THE DUSTER ON OUTPUT SCREEN.

           IT IS DEFIED IN THE CONIO.H HEADER FILE.

            PRINTF() IS USED TO PRINTF THE INFORMATION OR DATA IN THE OUTPUT SCREEN.

            IT SHOULD BE ENCLOSED WITH IN THE DOUBLE QUOTES.[PRINTF("")].

              IT IS DEFINED IN THE HEADER FILE STDIO.H.

            GETCH() IT IS A PREDEFINED FUNCTION WHICH IS USED TO HOLD THE OUTPUT SCREEN.

SO I THICK NOW YOU UNDER STOOD ABOUT PROGRAMMING A LITTLE BIT.
