Re: memory allocation

Turbo C is a very old DOS compiler.
250*250 just happens to be very near the maximum value for a 16 bit unsigned int which is what under DOS is used as a pointer.

Use a 32 bit compiler if you want to allocate larger arrays.

Re: memory allocation

WAT YOU CAN DO IS JUST LIKE SUGESTED USE A NEWST COMPILER AND CHANGE YOUR DATA TYPE OF YOUR ARRAY. LIKE IF IT WAS INT ARRAY CHANGE IT TO long int array[] or unsigned long int array[];
hope i have helped you out.

Re: memory allocation

why can't you use another compiler?
Cost can't be an issue as there are several modern compilers available free of charge.
Or are you stuck on a machine running DOS?
