LIMITS to array of structures.

Dear all i used the following code to store data in array of structures (struct items item[]) but when the array size becomes > 5990 the program terminates unexpectedly. can you please explain why?

Code:

#include <stdio.h>

#include <string.h>

#include <stdlib.h>



struct items

{

 char name[100];             

 char call_no[10];

 char author[100];

 char type[10];

 char borrower[100];

 int availability;

 char due_date[8];

 char genre[15];

 

};







int main()

{

 struct items item[5500]; // program stops unexpectedly

 char name[100];             

 char call_no[10];

 char author[100];

 char type[10];

 char borrower[100];

 int availability;

 char due_date[8];

 char genre[15];



  printf("Enter the name of the item with _ for spaces\n");

  fflush(stdin);

  fgets(name,100,stdin);

  printf("\n%s",name);



system("pause > null");

return 0;

}

Re: LIMITS to array of structures.

You need a bigger stack, most likely. Better still, if you want to store that much data, use a linked list instead, which if written correctly should use the heap, which has far more space available. 5500*(100+10+100+10+100+4+8+15)=1.82MB, which is way too much to be trying to store on your stack.
