    <p>I am learning about vector. I try to implement a code that print the struct element of a vector as displayed below. Many resources in the internet only teach me a simple vector. I get stcuk in expression when to print it. However, any suggestion for improving the quality and elegance of the code is open, although the change is fundamental (in struct or looping).</p> <p>Thank you very much.</p> <pre><code>#include "stdafx.h" #include &lt;iostream&gt; #include &lt;vector&gt; using namespace std; typedef struct _student { string name; int age; vector &lt;string&gt; subject; }student; int _tmain(int argc, _TCHAR* argv[]) { vector &lt;student&gt; x; //assmue at this point we do not know the number of students student y; //and I want to insert new information y.name ="John"; y.age =9; y.subject.push_back("biology"); y.subject.push_back("math"); y.subject.push_back("art"); x.push_back(y); //get new information again //and I want to insert new information y.name ="Bon"; y.age =12; y.subject.push_back("history"); y.subject.push_back("physics"); x.push_back(y); // then I want display all data cout &lt;&lt; "myvector contains:"; for (int i=0; i&lt;x.size(); i++) { cout &lt;&lt; "Student # " &lt;&lt; i+1 &lt;&lt;endl; cout &lt;&lt; " name : " &lt;&lt; x.at(i).name &lt;&lt;endl; //Reference in the internet only display a simple vector -- cout &lt;&lt; " age : " &lt;&lt; x.at(i).age &lt;&lt;endl; //I get stuck to express this and next part cout &lt;&lt;" Subject : "; for (int j =0; j &lt; x.at(i).subject.size(); j++) { cout &lt;&lt; x.at(i).subject.at(j); } cout &lt;&lt; endl; cin.get(); return 0; } </code></pre>

    1. COIn C++, `struct student {...};` works just as well.

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.
