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

It will print k because we don't add the %c with str. So it will print only massage which is in "".

Its because
The statement printf(str, "K\n"); is replaced with printf("%s" , "K\n");
// since str = "%s";
So it will print K.
The statement printf(str, "K\n"); is replaced with printf("%s" , "K\n");
// since str = "%s";
So it will print K.

@Kavyashree
your assumption is wrong, as it will ask a variable to print the data type, by the way the code offered from you shows error.

Its like
char str[]="good";
printf("%s",str);
its jst like replacing str with "good"
it becomes printf("%s","good");
output will be:
good
char str[]="good";
printf("%s",str);
its jst like replacing str with "good"
it becomes printf("%s","good");
output will be:
good

Dont worry Kavya your assumption is absolutely.
The code what You have written is true.
And, Hann it is not necassary to ask a variable to print the data type, since it takes as null if not assigned

how str="%s" is true
because str is a pointer which store adress of characters

str will store address of variable if and only if variable is preceded by &
otherwise it will store value of variable.
