    <p>Let say i have a text file with</p> <pre><code>today is today but tomorrow is today tomorrow </code></pre> <p>then using maps how can i keep track of the words that are repeated? and on which line it repeats? so far i have each string in the file read in as a temp and it is stored in the following way:</p> <pre><code> map&lt;string,int&gt; storage; int count = 1 // for the first line of the file if(infile.is_open()){ while( !infile.eof() ){ getline(in, line); istringstream my_string(line); while(my_string.good()){ string temp; my_string &gt;&gt; temp; storage[temp] = count } count++;// so that every string read in the next line will be recorded as that line. } } map&lt;string,int&gt;::iterator m; for(int m = storage.begin(); m!= storage.end(); m++){ out&lt;&lt;m-&gt;first&lt;&lt;": "&lt;&lt;"line "&lt;&lt;m-&gt;second&lt;&lt;endl; } </code></pre> <p>right now the output is just</p> <pre><code>but: line 1 is: line 2 today: line 2 tomorrow: line 2 </code></pre> <p>But instead.. it should print out(no repeating strings):</p> <pre><code>today : line 1 occurred 2 times, line 2 occurred 1 time. is: line 1 occurred 1 time, line 2 occurred 1 time. but: line 1 occurred 1 time. tomorrow: line 2 occurred 2 times. </code></pre> <p>Note: the order of the string does not matter.</p> <p>Any help would be appreciated. Thanks.</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.
