    <p>Okay, I think this is what you want:</p> <pre><code>#include &lt;iostream&gt; #include &lt;string&gt; #include &lt;vector&gt; #include &lt;boost/algorithm/string.hpp&gt; using namespace std; int main() { // Read a line from stdin string line; getline(cin, line); vector&lt;string&gt; str_vec; boost::split(str_vec, line, boost::is_any_of(" ,")); if (str_vec.size() == 3) { string last = str_vec[0]; string first = str_vec[1]; string middle = str_vec[2]; std::cout &lt;&lt; "First=" &lt;&lt; first &lt;&lt; " Last=" &lt;&lt; last &lt;&lt; " Middle=" &lt;&lt; middle &lt;&lt; endl; } } </code></pre> <p>If you don't want to use (or don't have) boost libraries, you can check the below version instead. The comments should help you understand each block of the code.</p> <pre><code>#include &lt;iostream&gt; #include &lt;string&gt; using namespace std; int main() { // Read a line from stdin string line; getline(cin, line); // Erase all commas while (true) { size_t comma_pos = line.find(","); if (comma_pos != std::string::npos) { line.erase(comma_pos, 1); line.insert(comma_pos, " "); } else break; } // Change all two spaces to only one space while (true) { size_t space_pos = line.find(" "); if (space_pos != std::string::npos) line.erase(space_pos, 2); else break; } // Tokenize the names size_t end_last_pos = line.find(" "); if (end_last_pos == string::npos) { cout &lt;&lt; "Missing last name" &lt;&lt; endl; return 1; } string last = line.substr(0, end_last_pos); size_t end_first_pos = line.find(" ", end_last_pos + 1); if (end_first_pos == string::npos) { cout &lt;&lt; "Missing first name" &lt;&lt; endl; return 1; } string first = line.substr(end_last_pos + 1, end_first_pos - end_last_pos - 1); size_t end_middle_pos = line.find(" ", end_first_pos + 1); string middle; if (end_middle_pos == string::npos) middle = line.substr(end_first_pos + 1); else middle = line.substr(end_first_pos + 1, end_middle_pos - end_first_pos - 1); // Print the names std::cout &lt;&lt; "First='" &lt;&lt; first &lt;&lt; "' Last='" &lt;&lt; last &lt;&lt; "' Middle='" &lt;&lt; middle &lt;&lt; "'" &lt;&lt; endl; } </code></pre>

Guidance
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.
