Arrays

A collection of elements of same type

      float x[100];

• first element of array is x[0]

• last element of array is x[99]

Initializing array elements

      float x[3] = {1.1, 2.2, 3.3};
      float y[] = {1.1, 2.2, 3.3, 4.4};

• can let the compiler calculate the dimension

Multi-dimensional arrays

      float m[4][4];
      int m2[2][3] = { {1, 2, 3},
                       {4, 5, 6} };

• elements appear row-wise

• in other languages elements may appear column-wise
