Answer / vignesh1988i
the printf and sprintf functions are used to output to the
screen.....
in printf... just we can print the necessary things as
we wanted
SYNTX is:: printf("format specifiers..(%d or %c
etc)",list of agruments..(arg1,arg2... arg n);
hrewr this function directly output whatever you are giving
inside ....
but sprintf is called Stream printf... where it will store
whatever we output to the screen in an array (ie..stream)
and then output to the screen;;;
sprintf(array base address,"format specifications",variables);

Answer / jack
The printf subroutine converts, formats, and writes the
Value parameter values, under control of the Format
parameter, to the standard output stream.
The sprintf subroutine converts, formats, and stores the
Value parameter values, under control of the Format
parameter, into consecutive bytes, starting at the address
specified by the String parameter. The sprintf subroutine
places a null character (\0) at the end. You must ensure
that enough storage space is available to contain the
formatted string.

Answer / manoj
i agree with Vignesh, and one more thing i would like to
add is,
ex:
char b[100];
sprintf( b, "Formatted data: %d / %f", i, f );
In above program, in array b string "Formatted data: %d / %
f" with proper i and f value will be stored.
it will not be printed on the output screen.

sprintf: This Writes formatted data to a character string in
memory instead of stdout
Syntax of sprintf is:
#include <stdio.h>
int sprintf (char *string, const char *format
[,item [,item]...]);
Here
String refers to the pointer to a buffer in memory where the
data is to be written. Format refers to pointer to a
character string defining the format. Each item is a
variable or expression specifying the data to write.
The value returned by sprintf is greater than or equal to
zero if the operation is successful or in other words the
number of characters written, not counting the terminating
null character is returned. And return a value less than
zero if an error occurred.
printf: Prints to stdout
Syntax for printf is:
printf format [argument]...
The only difference between sprintf() and printf() is that
sprintf() writes data into a character array, while printf()
writes data to stdout, the standard output device.

Write a function expand(s1,s2) that expands shorthand notations like a-z in the string s1 into the equivalent complete list abc...xyz in s2 . Allow for letters of either case and digits, and be prepared to handle cases like a-b-c and a-z0-9 and -a-z. z-a:zyx......ba -1-6-:-123456- 1-9-1:123456789987654321 a-R-L:a-R...L a-b-c:abbc
