Here is our first C program

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

              welcome.c

#include <stdio.h>

main()

{

   printf("\nWelcome to the world of C");

}

Before getting into minute details of the syntax, there are few points which you have to know about C programming.

* C is a compiler based language which means the whole program is translated into machine code before execution

* C language is case sensitive. This means main() and Main() are not the same

* Every C program must have a function called main()

* main() is a reserved word and cannot be MAIN() or Main()

* main() is a function and it is the first function to be executed in a C program

More about this program

# include ...as of now just note the point that it include the contents of another file at the beginning of the program

main() is a function

{} is a code block which has C syntax

printf() is a library function which displays the output.

There are lot more points to explain, but let me take you through step by step.
