Yes, and what happens when someone sees this:

scanf function:

scanf("expression",...);


and then writes:
/**********************************/
void f(void)
{
 char *str;

 scanf( "%s\n",str);  // str is not initialized!!!!
}

/***********************************/
(For non-geeks, the computer would end up sticking a bunch a 
characters into a random place.  It could be anywhere.  It could be 
somewhere harmless.  It could be into the code that launches the 
missle!)
