Answer 1

You should specify the size of your array:

Color color[HEIGHT][WIDTH];

Answer 2

You are trying to create an array without specifying its size. If the size is dynamic, you should use pointers instead. type x[][]; is always an error, regardless of type. You can initialize your array though, int x[] = {10,11}; // ok or int[][2]={{1,2},{1,2},{1,3}}; // also works

Answer 3

Your definition of color lacks sizes for the subscripts. Therefore, the compiler cannot determine how much space to allocate for color.

Answer 4

you're not specifying the size for the two-dimensional array as it seems. maybe that's causing the problem?
