    <p>I have a vector of vector like this:</p> <p>a: 0 1 0</p> <p>b: 1 0 1</p> <p>c: 0 1 1</p> <p>This part of my programm works. After I want to delete the 0 so I use remove_if and I want to replace the 1 by t and the position so I use replace_if for finally have something like</p> <p>a: t2</p> <p>b: t1, t3</p> <p>c: t2, t3</p> <p>These 2 things doesn't work on my program and I don't have idea anymore. I think one of the problem is that I want to have the "t" in a int but I don't know if I can use a string for this or not.</p> <p>Here is my code:</p> <pre><code>#include &lt;iostream&gt; #include &lt;vector&gt; #include &lt;iterator&gt; int main (){ srand(time(0)); int e = (rand() % 10) + 3; int tim = (rand() % 10) +1 ; std::vector&lt; std::vector&lt;int&gt; &gt; myvector; std::cout &lt;&lt; "Time: 0 = Not available, 1 = available" &lt;&lt; std::endl; for(int vec = 0; vec &lt; e; vec++){ std::vector&lt;int&gt; newVector(tim); for(int i = 0; i &lt; tim; i++){ newVector[i] = (rand() % 2); } myvector.push_back(newVector); std::cout &lt;&lt; "The Time " &lt;&lt; (vec+1) &lt;&lt; " is "; for(int b = 0; b &lt; tim; b++){ int value = myvector[vec][b]; std::cout &lt;&lt; " " &lt;&lt; value &lt;&lt; " "; } } //Delete the 0 in time int int_to_remove = 0; remove_if(myvector.begin(), myvector.end(), int_to_remove); std::cout &lt;&lt; "The new Time "&lt;&lt; std::endl; copy(myvector.begin(), myvector.end(), output); //Change the name of 1 to t1 int int_to_replace = 1; replace_if(myvector.begin(), myvector.end(), int_to_replace, t(tim)); std::cout &lt;&lt; "The new Time"&lt;&lt; std::endl; copy(myvector.begin(), myvector.end(), output); return 0; } </code></pre> <p>Thanks</p>

    1. COPlease show us a _complete_ example. The code in your question is missing things, like `output` and `t`.

    2. CODo you just want to **show** a `t` in the printed output, or do you want to have a vector of elements whose value is actually `"t1"`, `"t2"`, etc.? If you want such a collection, then the elements must be strings. Integers are integers.

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.
