Three-dimensional Array in C A three-dimensional array is an array of two-dimensional arrays, where each element is a two-dimensional array. A 3D array needs three subscripts to define depth, row, and column. Imagine the students appearing for an exam are seated in five halls, each hall having twenty rows of desks, and each row has 5 tables. Such an arrangement is represented by a three dimensional array such as − Students[hall][row][column] To locate each student, you need to have three indices, hall number, row and column of his table in the hall. With three dimensions: rows, columns, and slices. The rows are represented by the first index, the columns are represented by the second index, and the slices are represented by the third index here are some applications of 3D arrays in real life:  Medical imaging: 3D arrays are used to store medical images, such as MRI scans and CT scans. This allows doctors to view the images from different angles and to see the structures in the body in three dimensions.  Computer graphics: 3D arrays are used to store 3D models of objects. This allows computer graphics artists to create realistic and interactive 3D scenes.  Video games: 3D arrays are used to store the game world. This allows the game to be rendered in three dimensions and to allow the player to move around the world freely.  Virtual reality: 3D arrays are used to store the virtual world. This allows the user to interact with the virtual world in a realistic way.  Data visualization: 3D arrays can be used to visualize data in three dimensions. This can be helpful for understanding complex data sets  3D printing: 3D arrays can be used to store the data for 3D printed objects. This allows 3D printers to create objects with complex shapes and structures.  Machine learning: 3D arrays can be used to store data for machine learning models. This allows machine learning models to learn from 3D data and to make predictions about the real world.  Robotics: 3D arrays can be used to store data for robots. This allows robots to navigate their environment and to interact with objects in the real world. Example of Three-dimensional Array The following program stores numbers in a 3 X 3 X 3 array − Open Compiler #include int main(){ int i, j, k; int arr= { { {11, 12, 13}, {14, 15, 16}, {17, 18, 19} }, { {21, 22, 23}, {24, 25, 26}, {27, 28, 29} },  { {31, 32, 33}, {34, 35, 36}, {37, 38, 39} }, }; printf("Printing 3D Array Elements\n"); for(i=0;i
