Subj : General Protection Fault

I can cause a general protection fault quite easily, and I know exactly why, 
but I don't know the correct technique to prevent getting one. 

Here is the code: 

#include <stdio.h>
void main()
  {
  char name[50] ;
  printf("Hello World!\n");
  printf("Enter your name...\n") ;
  gets(name);
  printf("Hello %s\n",name) ;
  }

When I enter a name quite a bit longer than 50 bytes, I get the 
fault.  How does one code in C/C++ to make sure this is not allowed
to happen?    

I suspect it comes down to working with pointers... and using a lower level interface than gets().   

Thanks, Todd
