    <p>I need to get the result from K (number of students) but in case 2 ... program fills up all 30 places in the array with (if K=2) two number and other 28 are some kind of 38392839238 .. .some thing like that, here is my code:</p> <pre><code>int main() { int i,n,k; unsigned int m[30], a[30], b[30]; int ch=0, nech=0; cout&lt;&lt;"Number of students (max30)";cin&gt;&gt;k; for(i=0; i&lt;k; ++i) { cout&lt;&lt;i+1&lt;&lt;". Student number: "; do { cin&gt;&gt;m[i]; } while(!(m[i]&gt;=1e7 &amp;&amp; m[i]&lt;1e8)); if(m[i]%2==0) { a[ch]=m[i]; ch++; } else { b[nech]=m[i]; nech++; } } cout&lt;&lt;endl; cout&lt;&lt;"\nAll numbers: "&lt;&lt;endl; for(i=0; i&lt;k; ++i) cout&lt;&lt;m[i]&lt;&lt;"\t"; loop: cout&lt;&lt;endl; cout&lt;&lt;"\nChoose 1 to see Even and Odd numbers: "; cout&lt;&lt;"\nChoose 2 to see ascending order: "; cout&lt;&lt;"\nChoose 3 to exit: "; cout&lt;&lt;"\nEnter Your choise: "; cin&gt;&gt;n; switch(n) { case 2: { { int e=sizeof(m) / sizeof(m[0]); sort(m,m+e); for(i=0;i&lt;e;++i) cout&lt;&lt;"\n"&lt;&lt;m[i]&lt;&lt;' '; } } goto loop; } } </code></pre> <p>This program wants to enter the number of students in class, after that it wants to enter their number in class and in CASE 2 i it need to make them in ascending order. For example: Number of students in class: 2 1. Student number: 12345678 2. Student number: 55555555</p> <p>and when you hit 2 for case2 it needs to make their ascending order, so result must be: 12345678 55555555 (from min to max). My program makes it but on the other 28 places (my array must be max 30) it puts another number = 3435973836</p>

    1. COCould you please make the introduction to your code clearer? Right now one needs to read the entire code to even understand what this is about. Also, your minimal example could probably be smaller.

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.
