Reply may be a bit late since I only found out about this site on 26 May. int a[2]; defines a[0], a[1]; int a[2][3]; defines a[0][0], a[0][1], a[0][2], a[1][0], a[1][1], a[1][2], This is because int a[2][3] can be read as struct { int b[3]; } a[2]; This would not be stored as a[0].b[0] followed by a[1].b[0] because the compiler will keep all the bs together.
