Usage Of %n

[Arun Prasath]

Hi all,

In 'C' i seen one format string %n and one example to
explain abt that.


Program:
**********

int main()
{
char a[]="WELCOME";
int i;
printf("%s%n",a,&i);
printf("The Total No of Printed Character is: %d",i);
return 0;
}


Output:
********
The Total No of Printed Character is: 7


Is this only the purpose of %n. I want to know some more abt it. If u
know any other functionality of %n plz give ur explanation with sample
code..


Thanks to all.

Hi Arun,

Looks interesting.. I have tried the code and it gives me the same
output.
I couldnot find anything relevant to your query.

Senthil...
