Basics

• Sometimes useful to have an array with more than one index (e.g. matrices)

• This can be done in C++

• Syntax: type arr_name[size_dim_1][size_dim_2]…[size_dim_n];

• Examples:

  • char page [30][100];
  • int matrix[2][3];
  • double 3d_picture[10][20][30];

• Elements in matrix: matrix[0][0], matrix[0][1], matrix[0][2], matrix[1][0], matrix[1][1], matrix[1][2]
