HOW TO CREATE a multy MAP for 3 data sets
<p>I have a huge amount of data set. I wish to use array to store these data. In more deatil,</p>

<p>In my array, i want to use 3 columns such as <code>Number   number_of_points  point_numbers</code>. For this i can create a array like <code>mypointstore[][]</code> (for example <code>mypointstore[20][3]</code>). But my problem is that i want to store point numbers in column 3 like, <code>20, 1, 32, 9, 200, 12</code> and etc.(<code>mypointstore[0][0]= 1</code>, <code>mypointstore[0][1]= 6</code> and <code>mypointstore[0][2]={ 20, 1, 32, 9, 200, 12 }</code>). I don’t know that is it posible to use array for this structure? If so, please help me to solve this problem.</p>

<p>I tried to use map like <code>map&lt;int,int,vector&lt;int&gt;&gt; mypointstore;</code> but i don’t know how to insert data into this map;
My some codes are here</p>

<pre><code>map&lt;int,int, vector&lt;int&gt;&gt; mypointstore;
size=20;
For (int i=0; i&lt;= size;i++){
Int det=0;
    For (int j=0; j&lt;= points.size();j++){//points is a one of array with my points
        If (points.at(j)&gt;Z1 &amp;&amp; points.at(j) &lt;=Z2){
    //Here i want to store i , det and poiznts.at(j) like i in 1st colum, det in 2nd and
     //pointnumber in 3rd colum) in each step of the loop it take a point                                                                                                                                                                                                 
     //number   //which satisfied the if condition so it should be include into my    
     // vector of map   
det++;
}
}
    // at here i want to change total det value into 2nd element of my map so it like (0)(6)( 20, 1, 32, 9, 200, 12)
}
</code></pre>

<p>similar procedure for the next step so finaly it should be</p>

<pre><code>(0)(6)( 20, 1, 32, 9, 200, 12)
(1)(10)( 20, 1, 32, 9, 200, 12, 233, 80, 12, 90)
(2)(3)( 3, 15, 32)
</code></pre>
