annoying problem that's a pain to figure out...........

Hi, below is a program that I copied out of the book(word for word) so that I could figure out more about input and output in C and for some wonderful reason it decides to crash on me sometimes . My question is why(I have no clue whatsoever, since the book is wrong(I'm 95% sure of that)). It's supposed to print out a small table, but that's all that I know about it. Program.....

// enumerating_items.c:

#include <stdio.h>
#include <stdlib.h>

#define NUMITEMS 4

char *names[4] = {"Bob", "Azmaria", "Rosette", "Chrno"};

int main()
{
  int loop;
  char temp[4][160];
  char name[20];
  int age;
  long amount;

  for(loop = 0; loop < NUMITEMS; loop++)
    sprintf(temp[loop], "%s %d %ld", name[loop], rand() % 20 + 18, rand() + 27500L);

  printf("%4s | %-20s | %5s | %9s\n", "#", "Name", "Age", "Amount");
  printf("-----------------------------------------------------------------------\n");

  for(loop = 0; loop < NUMITEMS; loop++)
  {
    sscanf(temp[loop], "%s %d %ld", &name, &age, &amount);

    printf("%4d | %-20s | %5d | %9ld\n", loop + 1, name, age, amount);
  }

  return 0;
}

Thank you in advance.

P.S.: This is not a homework assignment in any shape or way.

The line :

sprintf(temp[loop], "%s %d %ld", name[loop], rand() % 20 + 18, rand() + 27500L);

should be :

sprintf(temp[loop], "%s %d %ld", names[loop], rand() % 20 + 18, rand() + 27500L);

"name" should be "names"

try
sprintf(temp[loop], "%s %d %ld", names[loop], rand() % 20 + 18, rand() + 27500);
