With this article at OpenGenus, you will have complete idea of handling 3D arrays in C. OUTPUT enter the blocks, rows and columns: 2 3 3 Printf('enter the blocks, rows and columns: ') Īrr=(int ***)malloc(sizeof(int ***)*block) Īrr=(int *)malloc(sizeof(int)*column) Int block,row,column //variables for block, rows and columns Int main(int argc, char* argv) //command line arguments Printf('enter the elements in array a: ') //entering elements in array 'a'

Printf('enter the values in the array: ') Int num //will hold the value to be replaced Int i,j,k //variables for nested for loop Printf('enter the values in the array: ') Int i,j,k //variables for nested for loops Third for loop represents the number of columns.įollowing is the implementation in C: #include.Second for loop represents the number of rows.First for loop represents the blocks of a 3D array.In 3D array, if a user want to enter the values then three for loops are used.

In this type of declaration, we have an array of type integer, block size is 2, row size is 3 and column size is 3 and we have put curly braces after assignment operator.So the array will hold 0 in each cells of array. In this type of declaration, we have an array of type integer, block size is 2, row size is 3 and column size is 3.Here we have not stored any values/elements in the array.So the array will hold the garbage values. number of blocks of 2D arrays:2 |rows:3 |columns:3 Each subscript can be written within its own separate pair of brackets.Specify data type, array name, block size, row size and column size.I.e int arr, so the statement says that we want three such 2D arrays which consists of 3 rows and 3 columns.īlock(1) 1 2 3 block(2) 10 11 12 block(3) 19 20 21 third dimension represents the columns of 2D arrays.second dimension represents the rows of 2D arrays.first dimension represents the block size(total number of 2D arrays).int shows that the 3D array is an array of type integer.Int arr, it means a 2D array of type integer having 3 rows and 3 columns.It is just a simple matrix int arr //2D array contaning 3 rows and 3 columnsīut, what happen if we add one more dimension here,

If we want to visualize a 2D array, we can visualize it in this way: More dimensions in an array means more data can be stored in that array. It is specified by using three subscripts:Block size, row size and column size. A 3D array is a multi-dimensional array(array of arrays).
