    copied!<p>I'm getting a "set illegal indirection error" but I can't figure out what I am doing wrong. What I am trying to do is take input from input.txt file that has a form</p> <pre><code>string1 string2 string3 string4 etc. </code></pre> <p>And number the strings in ascending order without duplicates, then use them in some functions and store the values in struct StringInt. But I am getting this weird error and I don't know where to start fixing it.</p> <pre><code>struct StringInt { std::string name; // associate name and number for each input string int number; }; int main(int argc, char* argv[]) { tot_strings = 100; std::string vert1, vert2; std::set&lt;std::string&gt; inGraph(0, tot_strings); // this is the set in question std::set&lt;std::string&gt;::iterator sit; std::vector&lt;StringInt&gt; stringInts(tot_strings); // Edit: forgot to mention this initially StringInt* si; int icv1, icv2; std::ifstream myfile2 ("input.txt"); if (myfile2.is_open()) { while(myfile2 &gt;&gt; vert1 &gt;&gt; vert2) { myfile2 &gt;&gt; vert1 &gt;&gt; vert2; if (inGraph.find(vert1) != inGraph.end()) { // not sure if I do this correctly icv1 = i++; si-&gt;name = vert1; si-&gt;number = icv1; inGraph.insert(vert1); // here's the insert that might be stringInts.push_back(*si); // causing of the error } else { icv1 = si-&gt;number; } if (inGraph.find(vert2) != inGraph.end()) { icv2 = i++; si-&gt;name = vert1; si-&gt;number = icv2; inGraph.insert(vert2); stringInts.push_back(*si); } else { icv1 = si-&gt;number; } // use icv1 and icv2 as int inputs in functions below } </code></pre> <p>Does what I have make sense and how can I go about fixing the "set illegal indirection error"? Edited: included std::vector stringInts(tot_strings) that I had in my code but forgot to include in the example.</p>
