like every function what value is returned by scanf() and printf() in C.

They don't return values, they perform something. In other programming languages, there are 2 types of sub-routines - procedures and functions. In C there are only functions. So some of the functions behave like procedures and don't return anything.

They dont return values.they are predefined functions belonging to the stdio.h header file.They take input or printf somethng on the screen

What are you guys doing !
printf DOES return a value !!!!!

Check this declaration.... If you want take a look in the C++ help...

 int printf  (              const char *format [, argument, ...]);

It returns the length of displayed character's ... including ....
