    <p>The <code>numberOfStrings</code> variable is only updated once after the <code>for</code> loop has finished. You can also simplify this without the need to specify a large number of lines to read by checking the return value of <code>getline</code> for failure. If you try to read past the end of file is <code>getline</code> will return false.</p> <pre><code>numberOfStrings = 0; str = new std::string[1000000]; std::ifstream myfile("Read.txt"); if (myfile.is_open()) { std::string line; while(getline(myfile, str[numberOfStrings])) numberOfStrings++; myfile.close(); } </code></pre> <p>You can simplify this even further by using <a href="http://en.cppreference.com/w/cpp/container/vector" rel="nofollow"><code>std::vector</code></a>. To expand on the example provided in your answer <code>StringList</code> might look something like below.</p> <blockquote> <p>StringList.h</p> </blockquote> <pre><code>#include &lt;vector&gt; #include &lt;string&gt; class StringList { public: StringList(); void PrintWords(); private: size_t numberOfLines; std::vector&lt;std::string&gt; str; }; </code></pre> <blockquote> <p>StringList.cpp to read in single line into each string</p> </blockquote> <pre><code>#include "StringList.h" #include &lt;fstream&gt; StringList::StringList() { std::ifstream myfile("Read.txt"); if (myfile.is_open()) { std::string line; while(getline(myfile, line)) { lines_.push_back(line); } myfile.close(); } numberOfLines = str.size(); } </code></pre> <blockquote> <p>StringList.cpp to read in single word into each string using <code>std::istream_itertor</code> and <code>std::copy</code></p> </blockquote> <pre><code>#include "StringList.h" #include &lt;fstream&gt; #include &lt;istream&gt; #include &lt;algorithm&gt; // std::copy #include &lt;iterator&gt; // istream_iterator StringList::StringList() { std::ifstream myfile("Read.txt"); if (myfile.is_open()) { std::copy( istream_iterator&lt;string&gt;(myfile), istream_iterator&lt;string&gt;(), back_inserter(str)); } numberOfLines = str.size(); } </code></pre> <blockquote> <p>Some other function to print the words</p> </blockquote> <pre><code>StringList::PrintWords() { for(size_t i = 0; i &lt; numberOfLines; ++i) { std::cout &lt;&lt; str[i] &lt;&lt; std::endl; } } </code></pre> <hr> <p><sub>I also recommend avoiding using <code>using namespace std</code> in your code. It pulls everything from <code>std</code> into the current scope (typically the global namespace) and can cause conflicts with identifiers.</sub></p>

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.
