1)printf() is a built in library function which is defined
in <stdio.h> header file...
2) in printf(); function we can pass
1) entire string within "...." like :
eg: printf("my name is vignesh");

2) string with list of variables like :
eg: printf("%d%d" , i,j);
| |
first second
argument argument

3) like every function returns a value , PRINTF returns the
no. of characters which is inside "...".
eg: printf("%d",printf("hai how are u?"));
the output will be 14.....

4) printf() function is having direct contact with VDU
(video display unit) in the system..... so only it is
displayin every thing in the screen...........
