Hai kavyashree.
Printf ("%s", "k\n") ; why %s is not shown as output which in double quotes. Only k as output.

#include<stdio.h>
int main()
{
char *str;
str = "hi %s hello";
printf(str,"hh");
return 0;
}
Here printf function take the address of str it is pointing to the "hi %s hello"
it's print hi hh hello
%s will take address of hh
printf("%s")
it will print null
printf("%s","hi");
it's print hi
It takes address of string. Hope you are understand.
int main()
{
char *str;
str = "hi %s hello";
printf(str,"hh");
return 0;
}

printf("%s")

printf("%s","hi");

It is just like when we print hello wotld as
printf ( "%s", "hello world\n" ) Output will be hello world, similarly printf ( "%s", "k\n" ) ; output will be k itself..
printf ( "%s", "hello world\n" ) Output will be hello world, similarly printf ( "%s", "k\n" ) ; output will be k itself..

Why is the need for this kind of format: printf ("%s", "hello").
If we can simply print using: printf ("hello") ;.
TAKE A MOMENT Please!

@Kavya and others:Your concept is correct but then also it somehow depends on the arguments of printf() function ,if its just replacing the string then how come the following does not work ?
int main()
{
char s[]="goog";
printf(s);
return 0;
}
int main()
{
char s[]="goog";
printf(s);
return 0;
}

@Ravi.
Your code is working properly. O/P will be goog.

Str doesnot return.. so the value(k )inside brace isdisplayed..
