    <p>I am so confused why the cout statement is not printing the contents of the array c_braces_array in the function find_depth;</p> <p>All I am trying to do is pass an array and print its values.</p> <pre><code>#include &lt;iostream&gt; int find_depth(char c_braces_array[], int no_of_braces) { for(int i=0; i&lt;no_of_braces; i++) { std::cout&lt;&lt;"val is:"&lt;&lt;c_braces_array[i]&lt;&lt;"F\n"; } return 0; } int main() { char braces[100] = {0}; int ret_val = find_depth(braces, 100); std::cout&lt;&lt;ret_val; system ("pause"); return 0; } </code></pre> <p>O/P:</p> <blockquote> <p>...<br/> val is: F<br/> val is: F<br/> val is: F<br/> val is: F<br/> val is: F<br/> 0Press any key to continue . . .<br/></p> </blockquote> <p><img src="https://i.stack.imgur.com/8zECb.png" alt="enter image description here"></p> <p>Edit: I initialized the array to contain all 0s in the main. So I was expecting 0s to be printed. I am not sure where the O (as in Oh!) thing comes into context. Can someone explain a bit more on that?</p> <p>I was expecting this o/p</p> <blockquote> <p>val is:0 F<br/></p> </blockquote> <p>Edit - 2: Guys thanks. Thanks for pointing out the bug. Also I do not understand why the following line initializes only braces[0] with 'a' instead of the entire array. WHat is the correct way to init the entire array instead of running a for loop.</p> <p>Now my code looks as below.</p> <pre><code>main(){ ... char a_char = 'a'; char braces[100] = {a_char}; } find_depth(..) { ... std::cout&lt;&lt;"val is:"&lt;&lt;c_braces_array_ptr[i]&lt;&lt;"X\n"; } </code></pre> <p>O/P <br/> Inside main: a <br/> val is:aX <br/> val is: X <br/> val is: X <br/> val is: X <br/> val is: X <br/> val is: X <br/> val is: X <br/> val is: X <br/></p>

    1. COA character `0` is a null terminator, used to end strings, as opposed to `'0'`, which has the ASCII value `48`. You also shouldn't use `system("pause")`, as you have no guarantees what the `pause` program on someone else's computer will do.

    3. COSince you've initialized your `braces` array to all 0's, it's printing `no_of_braces` empty strings.

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.
