    <blockquote> <p>Now strPtr and strArray are considered to be string literals.</p> </blockquote> <p>No, they aren't. String literals are the things you see in your code. For example, the <code>"Hello"</code>. <code>strPtr</code> is a <em>pointer</em> to the literal (which is now compiled in the executable). Note that it should be <code>const char *</code>; you cannot legally remove the <code>const</code> per the C standard and expect defined behavior when using it. <code>strArray</code> is an array containing a copy of the literal (compiled in the execuable).</p> <blockquote> <p>Both the above statements should be illegal. compiler should throw errors in both cases.</p> </blockquote> <p>No, it shouldn't. The two statements are completely legal. Due to circumstance, the first one is undefined. It would be an error if they were pointers to <code>const char</code>s, though.</p> <p>As far as I know, string literals may be defined the same way as other literals and constants. However, there are differences:</p> <pre><code>// These copy from ROM to RAM at run-time: char myString[] = "hello"; const int myInt = 42; float myFloats[] = { 3.1, 4.1, 5.9 }; // These copy a pointer to some data in ROM at run-time: const char *myString2 = "hello"; const float *myFloats2 = { 3.1, 4.1, 5.9 }; char *myString3 = "hello"; // Legal, but... myString3[0] = 'j'; // Undefined behavior! (Most likely segfaults.) </code></pre> <p>My use of ROM and RAM here are general. If the platform is only RAM (e.g. most Nintendo DS programs) then const data <em>may</em> be in RAM. Writes are still undefined, though. The location of const data shouldn't matter for a normal C++ programmer.</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.
