C++ Program wont function with any number larger than 100, WHY?

}

in.open("Array.dat");

const long long int size = 100;
long long int array[size];

printRandArray(array);
sort(array, size);
printArray(array, size);

return 0;
}

Ok, to be more specific. The array works just fine with 100 for size but if you enter anything larger than 100 it will not print the unsorted, or if it is printing it it will not display it because I think its deleting it half way through the cycle. I need it to sort 500, and 10000. Please help!
