Please allow me to make a beginner's question. I'd like to declare an array of structures for holding data of a worksheet:
and I got an error message "Segmentation fault (core dumped)" when MAXROW=500. (size of struct row = 5244byte)Code:struct row {
int name;};
int age;
int dob;
...(many entries)...
main()
{struct row worksheet[MAXROW];}
....
As I did not get the error when MAXROW=10, the problem seems to be an available memory space, but I could also make it without the error under the following two versions of codes:
version1 (MAXROW=500)
version2 (MAXROW=500)Code:struct row {
int name;} worksheet[MAXROW];
int age;
int dob;
...(many entries)...
main()
{....}
Could anyone please point out what's wrong in the first code?Code:#include <stdlib.h>
struct row {int name;};
int age;
int dob;
...(many entries)...
main()
{struct row *worksheet;}
worksheet = calloc(MAXROW, sizeof(struct row));
....
