How to declare a three dimensional array

[Danzy83]

I want to know how to declare three dimensional arrays in C/C++ and how they work. Examples will do. Please help.

Maybe this link[^] will help get you started.

I have been to that site but it only talks about it without examples. I know it can for instance be declared as follows: int rates[10][4][3]; The declaration is what has been shown on the site. But I want to know how to initialise the array when it is declared, and know how the indexing will refer to a particular value in the initialising list.

OK, how about this[^] site.

Try the information here[^]. Although this only covers 2D arrays, you can think of the third dimension as a number of 2D arrays one on top of the other, the index increasing as you go further down the planes.

It's time for a new signature.

Like:

int Array3D[2][4][6] =
{
{
{ 1,2,3,4,5,6 },

    { 7,8,9,10,11,12 },

    { 13,14,15,16,17,18 },

    { 19,20,21,22,23,24 }
},

{
    { 77,78,79,80,81,82 },

    { 83,84,85,86,87,88 },

    { 89,90,91,92,93,94 },

    { 95,96,97,98,99,100 }
}

};

Use boost::multi_array[^] to create arrays of any dimensions.

A sample;

int array[3][4][5] = {
{ //[0][][]
{ 1, 2, 3, 4, 5 },//[0][1][]
{ 1, 2, 3, 4, 5 },//[0][2][]
{ 1, 2, 3, 4, 5 },//[0][3][]
{ 1, 2, 3, 4, 5 } //[0][4][]
},
{ //[1][][]
{ 1, 2, 3, 4, 5 },//[1][1][]
{ 1, 2, 3, 4, 5 },//[1][2][]
{ 1, 2, 3, 4, 5 },//[1][3][]
{ 1, 2, 3, 4, 5 } //[1][4][]
},
{ //[2][][]
{ 1, 2, 3, 4, 5 },//[2][1][]
{ 1, 2, 3, 4, 5 },//[2][2][]
{ 1, 2, 3, 4, 5 },//[2][3][]
{ 1, 2, 3, 4, 5 } //[2][4][]
}
};
