An array is a kind of aggregate data type. A single ordinary variable (a scalar) could be considered as a zero-dimensional array. A one-dimensional array is also known as a vector. A reference to an array element is written something like A[i,j,k] where A is the array name and i, j and k are the indices. The C language is peculiar in that each index is written in separate brackets, e.g. A[i][j][k].
