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; }
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.
