How to create a Three Dimensional List in C++ - Step by Step Examples

How to create a Three Dimensional List in C++ ?

Answer

To create a three-dimensional list in C++ using std::list, you can nest lists within lists to represent the multi-dimensional structure.

✐ Examples

1 Create and Populate a 3D List

In this example,

We include the necessary headers for iostream and list.
We define a 3D list using std::list<> with three levels of nesting.
We populate the 3D list with integers using nested loops to represent the multi-dimensional structure.
We print the elements of the 3D list in a structured format.

C++ Program

#include <iostream>
#include <list>

int main() {
    std::list<std::list<std::list<int>>> threeDList;

    for (int i = 0; i < 3; ++i) {
        std::list<std::list<int>> plane;
        for (int j = 0; j < 2; ++j) {
            std::list<int> row;
            for (int k = 0; k < 2; ++k) {
                row.push_back(i * 4 + j * 2 + k + 1);
            }
            plane.push_back(row);
        }
        threeDList.push_back(plane);
    }

    for (const auto& plane : threeDList) {
        for (const auto& row : plane) {
            for (const auto& element : row) {
                std::cout << element << " ";
            }
            std::cout << std::endl;
        }
        std::cout << std::endl;
    }

    return 0;
}

Output
