huge numbers are not acceptable , why?

[ArShAm]

Hi there
In this code , I need a huge table , but for numbers more than 259025 it
crashes , why?
How to fix that problem?

void main(void)
{
int Sorted[1000000];
Sorted[1] = 1;
}

also i have a table like this :
myTable *table[1000000];
till here is ok , but :
table[i]=&anothertabl e;
again crashes for more than that number
please help me to fix these problems

Regards
ArShAm

Try this

int *Sorted = new int[1000000];

//do your stuff
delete [] Sorted;

Try this

int *Sorted = new int[1000000];

or better
vector<int> Sorted(100000);

void main(void)
{
int Sorted[1000000];
Sorted[1] = 1;
}
Most likely because you have run out of stack space. The Sorted array
stores its data on the stack, which is often a limited resource. Given
the number 259025 * sizeof(int), my guess is that the stack size on your
platform is 1 MByte. Also note that main() doesn't return void; main()
always returns int.

One way to get around the stack size limitation is to allocate the array
on the heap as Ali R. suggested. But an even better way to do it is to
use std::vector which also stores its data on the heap but doesn't
require explicit resource management:

#include <vector>

int main()
{
std::vector<int > Sorted(1000000) ;
Sorted[1] = 1;

// No need to delete anything!
return 0;
}
also i have a table like this :
myTable *table[1000000];
till here is ok , but :
table[i]=&anothertabl e;
again crashes for more than that number

The same problem. The reason that the line myTable *table[1000000]
doesn't crash immediately is that it doesn't generate executable code
with many compilers. However as soon as you start accessing elements it
will access memory that is beyond the stack, hence the crash. Again
using std::vector should fix this problem.

Thanks Ali jan
The problem is here : ==> Sorted[i]=i;
if you remove this section , program works ;

in my code , the main thing was this :
myClass* table[1000000];//to here , its ok
table[i]->datd=data;//here is problem , that program crashes
Thanks

1. Don't top-post. Replies are interwoven or appended to the
bottom of a reply, like this one.
2. We need to see your class declaration and the smallest amount
of "compilable " code which demonstrates the issue.
3. Tell us what the expected behavior is and the actual behavior.
4. The possibilities:
4.1. Operator -> is overloaded incorrectly.
4.2. Operator = is overloaded incorrectly.
4.3. The index variable, i, is out of range.
4.4. The index variable, i, is a floating point value.
4.5. The compiler could not find a conversion function for
converting "data" to "datd" (if necessary).
As you can see, there are many possibilities, but we can't
narrow them down until you show some code (see #2 above).

Please read the Welcome.Txt and C++ FAQs below. They will
provide information on how to post as well as other excellent
information.

Well, now you are posting different problem. You are declaring an array of
pointers to your class but you aren't initializing the array with anything.

In this case you would use the vector class

vector<myClass> Table(1000000);

or if you are getting the pointers to the objects from someplace else

vector<myClass *> Table(1000000);
