    <p>So I have these two functions at the top of my program:</p> <pre><code>string deletespaces(string sentence){ sentence.erase(std::remove(sentence.begin(), sentence.end(), ' '), sentence.end()); return sentence; } </code></pre> <p>and</p> <pre><code>string checkpalindrome(string sentence){ deletespaces(sentence); if (sentence == string(sentence.rbegin(), sentence.rend())){ cout &lt;&lt; sentence &lt;&lt; " is a palindrome." &lt;&lt; endl; } if(sentence != string(sentence.rbegin(), sentence.rend())){ cout &lt;&lt; sentence &lt;&lt; " isn't a palindrome." &lt;&lt; endl; } } </code></pre> <p>This is my main body of code.</p> <pre><code>int main(){ int x = 1; string originalsentence; while (x == 1) { int a = 1; int input; string sentence; cout &lt;&lt; "Press 1 to reverse a string, 2 to check a palindrome, and anything else to quit: "; cin &gt;&gt; input; if(input == 1) { cout &lt;&lt; "Enter a sentence to reverse: "; cin.ignore(); getline(cin,originalsentence); originalsentence = sentence; cout &lt;&lt; string(sentence.rbegin(), sentence.rend()) &lt;&lt; endl; } if(input == 2) { cout &lt;&lt; "Enter a sentence to check: "; cin.ignore(); getline(cin,originalsentence); originalsentence = sentence; checkpalindrome(sentence); } cout &lt;&lt; "Hit 1 if you want to continue, anything else to quit: "; cin &gt;&gt; x; } } </code></pre> <p>So here is my problem. I am able to put in my choice about whether to reverse a string or check whether the string is a palindrome. However, when I try to reverse the string, it simply gives a blank line, then asks whether I want to continue. When I ask to check a palindrome, it simply says "is a palindrome" regardless of what I input. Any ideas?</p>

    1. COA suggestion: why don't you just enclose `cout << sentence << " isn't a palindrome." << endl;` with an `else`?

    2. COSo I made that change, and now it outputs "is a palindrome" Segmentation fault (core dumped)

    3. COYou're not using the return value from `deletespaces`, and `checkpalindrome` should be returning a string but isn't. You should also think about why you get data into `originalsentence` and then immediately overwrite it with `sentence`.

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.
