    <p>I am able to achieve cartesian product of static number of arrays in C.But I would like to build a code dynamically taking the number of input arrays.Can someone shed some light how to do this "only using arrays".If it's not possible with arrays please suggest me other solution.Thank you.Here is my code below for cartesian product of 3 arrays.</p> <pre><code>#include&lt;stdio.h&gt; int main(void) { int array1[100]; int array2[100]; int array3[100]; int cartesian_array[100][100]; int m,n,o; int i,j; int p=0,q=0,r=0; int x,y,z; int cartesian_arr_row_len; int cartesian_arr_col_len; printf("Enter the size of first array:\n"); scanf("%d",&amp;m); printf("Enter the size of second array:\n"); scanf("%d",&amp;n); printf("Enter the size of third array:\n"); scanf("%d",&amp;o); printf("Enter the first array elements:\n"); for(i=0;i&lt;m;i++) scanf("%d",&amp;array1[i]); printf("Enter the second array elements:"); for(i=0;i&lt;n;i++) scanf("%d",&amp;array2[i]); printf("Enter the third array elements:"); for(i=0;i&lt;o;i++) scanf("%d",&amp;array3[i]); cartesian_arr_row_len=m*n*o; cartesian_arr_col_len=3; x=cartesian_arr_row_len/m; y=cartesian_arr_row_len/(m*n); z=o; for(i=0;i&lt;cartesian_arr_row_len;i++) { for(j=0;j&lt;cartesian_arr_col_len;j++) { if(j==0) { cartesian_array[i][j]=array1[p/x]; p++; } if(j==1) { cartesian_array[i][j]=array2[q/y]; q++; if(q&gt;=n*y) q=0; } if(j==2) { cartesian_array[i][j]=array3[r%z]; r++; } } } printf("The Cartesian Product of two arrays is:\n"); for(i=0;i&lt;cartesian_arr_row_len;i++) { for(j=0;j&lt;cartesian_arr_col_len;j++) { printf("%d\t",cartesian_array[i][j]); } printf("\n"); } return 0; } </code></pre>

    1. COSo you're asking for suggestions how to take the cartesian product of _n_ sets?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
