bus-error

I'm playing with C and I've run into this error:

#include <stdio.h>
int main ()
{
 char* foo;
 scanf("%s", foo);
 printf("entered %s", foo);
 return 0;
}

scanf takes pointer, foo is pointer, yet I get bus error. How can I make it work?

In a C++ program that doesn't contain legacy C code, is there a guideline regarding the maximum number of levels of indirection that should be used in the source code?
