An array with more than one index value is called a Multidimensional array in C or other programming language. Array can be single, two, three, up to n-dimension.
But most of programmers only used up to three dimension array in their codes.
All the array below is called a single-dimensional array.
int list[5]={2,3,4,5,6};
OR
int list[] = {2,1,3,7,8};
Two dimensional array is
int list[2][2] = {{1,12},{13,20}};
OR
int list[2][2] = {
{2,3},
{3,2}
};the complex one three dimensional array is
int list[2][2][2] = {
{
{2,4}
},
{
{4,2}
}
};
OR
int list[2][2][2] = { { {2,4} },{ {2,4} } };Declaration of Multidimensional Array in C
To declare a multidimensional array you can do follow the syntax
data_type array_name[size][size][size];The number of square brackets specifies the dimension of the array.
For example to declare two dimensions integer array we can do as follows:
int matrix[3][3]; Initializing Multidimensional Array
You can initialize an array as a single-dimension array. Here is an example of initializing a two dimensions integer array:
int matrix[3][3] = { {11,12,13}, {21,22,23}, {32,31,33} };
Or
int matrix[3][3] = {11,12,13,21,22,23,32,31,33 };
