array offset

hi all,

I am describing my problem below,

I am using LPC2214, keil Uv3 compiler

I am definig one global array of the size Arr[120][120]
I am initilizing the whale array with the value 254.

unsigned char Array[100][100]

main()
{

Array[0][0]=0;
Array[0][1]=1;
. .
Array[100][100]=10000;

Init_Extint2();

printf("%c",Array[0][0]);

}

I am setting interrupt as rising edge sensitive.

After initializing interrupt when i read value of Array[0][0] its not
giving false value.

If i read the whale array than I found that there is an offset in the
base address of the array[100][100].

I mean the value get shifted to some offset. And the value of the offset
is also random.

Please see if somebody can help me.

thanks in advance
