Body
<p>I declared the size of the array to be 2 and I tried inserting on the 3rd array position. The insert function is supposed to throw -1 when the position > size+1(using pos-1 when assigning the element into the array) but the throw is not stopping the assignment for the 3rd array position so I am getting a segmentation fault.</p> <pre><code>template <class T, int N> class person : public people<T> { private: T a[N]; int size; public: person(); virtual void insert(int pos, T info); virtual T show(int pos); }; template<class T, int N> person<T,N>::person(){ size = 0; } template <class T, int N> void person<T,N>::insert(int pos, T info){ if (pos <= 0 || pos > size+1) throw -1; a[pos-1] = info; ++size; } template <class T, int N> T person<T,N>::show(int pos){ if ( pos <= 0 || pos > size+1 ) throw -1; return a[pos-1]; } void putin( people<name>*& aPerson ) {//passing aPerson itself string first("Julia"), last("Robert"); name temp(first, last); string ft("Delilah"), lt("McLuvin"); name temp2(ft, lt); string fst("oooh lala"), lst("broomdat"); name temp3(fst, lst); try{ aPerson-> insert(1,temp); aPerson-> insert(2,temp2); aPerson-> insert(3,temp3); } catch(...){ cout<< "error\n";} } int main(){ people<name>* aPerson = new person<name, 2>(); putin(aPerson); try{ cout << aPerson->show(1); cout << aPerson->show(2); cout << aPerson->show(3); } catch(...){ cout<< "error\n";} return 0; } </code></pre>

1. COThe first instance of the word `throw` appears about half way through this massive, poorly-spaced piece of code you pasted up here. Would it be possible for you to trim out all the irrelevant bits? No one needs to read your entire project to help you figure out the error.

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.
