Thread: killed message

I need a really large array to conduct a
series of calculations. When I declare...

int Uq[5764801][3];

...my program compiles without warning or error (regardless of whether I actually include the calculation in the program or delete it).

When I execute the program, I get an error message "killed" on the screen.

Obviously the array is too big. How do I get C to handle extremely large arrays?

THANKS,
