  1. POAttempting to create a queue - issue with crashing C++
    text
    copied!<p>For my data structures course I have to create a queue that takes input from a .dat file, and organizes it based on high priority (ONLY if it's 1) and low priority (2 3 4 or 5). There must be two queues, * indicates how many to service (or remove). The .dat file looks like:</p> <pre><code>R 3 T 5 W 1 A 4 * 3 M 5 B 1 E 1 F 2 C 4 H 2 J 1 * 4 * 1 D 3 L 1 G 5 * 9 = </code></pre> <p>Here's the main.cpp</p> <pre><code>int main () { arrayQueue myHigh; //creates object of arrayQueue arrayQueue myLow; //creates another object of arrayQueue while(previousLine != "=") //gets all the lines of file, ends program when it gets the line "=" { getline(datfile, StringToChar); if (StringToChar != previousLine) { previousLine=StringToChar; //sets previousline equal to a string number = StringToChar[2]; //the number of the data is the third line in the string istringstream ( number ) &gt;&gt; number1; //converts the string to int character = StringToChar[0]; //the character is the first line in the string } if (number1 == 1) //if number is 1, sends to high priority queue myHigh.addToQueue(number1); else if (number1 == 2 || number1 == 3 || number1 == 4 || number1 == 5) //if number is 2 3 4 or 5 sends to low priority queue myLow.addToQueue(number1); } datfile.close(); system ("pause"); } </code></pre> <p>And here's the array class:</p> <pre><code>void arrayQueue::addToQueue(int x) { if (full() == true) cout &lt;&lt; "Error, queue full \n"; else { fill = (fill+1)%maxSize; queueArray[fill] = x; cout &lt;&lt; x &lt;&lt; endl; //testing that number is actually being passed through count++; size++; } } </code></pre> <p>However, the output that I get is just:</p> <pre><code>3 5 </code></pre> <p>and then it crashes with no error.</p> <p>I'm not sure where I should go, I haven't created two objects of a class OR used a file to read data before in C++. Did I do that correctly? I think it's just feeding 3 and 5 into the high priority queue, even though it's not supposed to do that. </p>
