here 's an example of static and dynamic allocation...
(my prev example was only about single dimensional arrays...)
a 2dimensional array of 4450 x 4450
(change the dimension to 1450 x 1450 if u find the
first size to be too big)
TEST.C
#include <stdio.h>
int main()
{
double a[4450][4450];
a[4449][0] = 999;
printf( "%lf\n", a[4449][0] );
return 1;
}
TEST2.c
#include <stdio.h>
int main()
{
double **a;
int i;
a = (double**) calloc( 4450, sizeof(double*) );
for ( i=0; i <1450; i++ )
{
a[i] = (double*) calloc( 4450, sizeof(double) );
}
a[4449][0]=999;
printf( "%lf\n", a[4449][0] );
return 1;
}

i am using a array of size 1024*1024
it gives segmentation fault
it works with 512*512
my menory size is 128 mb and 512 swap
i have enough memory space and using gcc 3.2 v
may be i need to increase the memory size
