#include <stdio.h>
int main(void)
{
int i,j,k;
char st;
printf("enter string\n");
scanf("%s", st);
printf("the entered string is %s\n", st);
}
Compiling above program gives me a warning:
warning: format '%s' expects argument of type 'char *', but argument 2 has type 'int' [-Wformat]
palindrom.c:8:1: warning: format '%s' expects argument of type 'char *', but argument 2 has type 'int' [-Wformat]
What am I doing wrong here?
This is what happens when I run it:
$ ./a.out
enter string
kiaaa
the entered string is (null)
Edit:
Here is another version of the code (made char st;
into char *st
):
#include <stdio.h>
int main(void)
{
int i,j,k;
char *st;
printf("enter string\n");
scanf("%s", st);
printf("the entered string is %s\n", st);
}
However, it behaves the same on runtime.
