<p>This piece of code is part of a large source code but the bug is here.</p> <pre><code>int solve(int* unsolved_var) { int i; for (i = 0; unsolved_var[i] != 0; i++) { int n; for (n = 1; n <= 9; n++) { //if (!numInBox(unsolved_var[i], n)==1 || !numInLine()==1) printf("%d %d\n", n, unsolved_var[i]); numInBox(unsolved_var[i], n);//ERROR OCCURS HERE } } } int numInBox(int space, int n)//space is always three digits long { printf("this should print but doesnt(segmentation fault)"); char unsolved_str[3]; sprintf(unsolved_str, "%d", space);//converts int into char[] printf("%s",unsolved_str);//confirms int check[3] = {atoi(unsolved_str[0]), 0, atoi(unsolved_str[2])};//converts char[] to int[] </code></pre> <p>Complete Code...its long it runs fine thou.

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.
