C Fundamentals

The C program is a set of functions. A C program always starts executing in a special function called main() function. Your program ends when main()'s closing curly brace is reached. One of the most common library functions is called printf(). This is C's general-purpose output function. The printf() function is quite versatile, allowing many variations. Its simplest from is shown here:

        #include<stdio.h>

        main()
          {

       printf("Hello programmer\n");

       return 0;
          }

The first line is the #include directive. C program uses this directive to load  external function library - stdio is C library which provides standard input/output printf is a function which is declared in the file called stdio.h .

The next is the main function the first entry point of all C programs.C program logic start from the beginning of main function to the its ending.

And finally is the printf function which accepts a string parameter. The printf function is used to print out the message to the screen.
