    <p>I'm working on a project and every time I go to set example[4].m_dArray[3], the program crashes. I can set the value of every other variable up until I get to example[4].m_dArray[3]. Any help would be appreciated!</p> <p>Prog1Class.h:</p> <pre><code>#include "Prog1Struct.h" #pragma once #include &lt;iostream&gt; #include &lt;string.h&gt; using namespace std; class Prog1Class { private: Prog1Struct example[4]; public: Prog1Class(); ~Prog1Class (); void setStructData(); void getStructData(); void ptrFunction(); void refFunction(); void printStruct(); void printData(); }; </code></pre> <p>Prog1Struct.h:</p> <pre><code> #pragma once #include &lt;string.h&gt; struct Prog1Struct { int m_iVal; double m_dArray[4]; char m_sLine[80]; }; </code></pre> <p>Prog1Class.cpp:</p> <pre><code>#include "Prog1Class.h" #include "Prog1Struct.h" #include &lt;iostream&gt; #include &lt;string.h&gt; using namespace std; Prog1Class::Prog1Class() { } Prog1Class::~Prog1Class() { delete &amp;example[4]; } int main() { Prog1Class *aClass = new Prog1Class(); aClass-&gt;setStructData(); aClass-&gt;printData(); return 0; } void Prog1Class::setStructData() { for(int i=0;i&lt;5;i++) { cout &lt;&lt; "Enter an integer: "; cin &gt;&gt; example[i].m_iVal; for(int j=0;j&lt;5;j++) { cout &lt;&lt; endl &lt;&lt; "Enter a double: "; cin &gt;&gt; example[i].m_dArray[j]; } cout &lt;&lt; endl &lt;&lt; "Enter a string: "; cin.ignore(256,'\n'); cin.getline(example[i].m_sLine, 80, '\n'); cout &lt;&lt; endl; } } void Prog1Class::getStructData() { } void Prog1Class::printData() { for(int i=0;i&lt;5;i++) { cout &lt;&lt; example[i].m_iVal; for(int j=0;j&lt;5;j++) { cout &lt;&lt; example[i].m_dArray[j]; } cout &lt;&lt; example[i].m_sLine; } } </code></pre>

    1. COShow the header files. There's not enough information to disgnose the problem let alone offer a solution. But `delete &example[4];` is completely wrong.

    2. COTwo things: use `<string>` header instead of `<string.h>` and in `main ` don't create an object on the heap (`Prog1Class *aClass = new Prog1Class();`), just declare a local object (`Prog1Class aClass;`).

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.
