    <p>The following is a problem which i encountered while writing a program where i prompt a user to input as many values as i want, and then i print the results for each integer thus entered.</p> <p>I was suggested to use dynamic memeory allocation by <a href="https://stackoverflow.com/users/319824/gcc">https://stackoverflow.com/users/319824/gcc</a> in my last question <a href="https://stackoverflow.com/questions/11536306/how-to-test-my-program-against-an-input-test-case-file/11536412#11536412">How to test my program against an input test case file</a>.</p> <hr> <p>My code is as follows:</p> <pre><code>#include &lt;stdio.h&gt; #include &lt;stdlib.h&gt; struct node { int data; struct node *next; }*start; void insertatend(int d) { struct node *n; n=(struct node *)malloc(sizeof(struct node)); n-&gt;data=d; n-&gt;next=NULL; if(start==NULL) { start=n; } else { struct node *tmp; for(tmp=start;tmp-&gt;next!=NULL;tmp=tmp-&gt;next); tmp-&gt;next=n; } } int max(int a,int b) { int c=(a&gt;b)?a:b; return c; } int maxCoins(int n) { int arr[n+1],i; arr[0]=0; arr[1]=1; arr[2]=2; arr[3]=3; if(n&gt;2) { for(i=3;i&lt;=n;i++) { int k= arr[(int)(i/2)]+arr[(int)(i/3)]+arr[(int)(i/4)]; arr[i]=max(i,k); } } return arr[n]; } int main(void) { int coins,i; start=NULL; struct node*p; while(scanf("%d",&amp;coins)) { insertatend(coins); } for(p=start;p!=NULL;p=p-&gt;next) { printf("%d\n",p-&gt;data); } getchar(); return 0; } </code></pre> <hr> <p>The program runs successfully. I am able to give any number of inputs, and if I try to break out by pressing CTRL + Z ,the program does not respond. Can't I use dynamic memory allocation for problems like these ? And if yes, where am i wrong ? </p>

    2. COCTRL+Z ends the input on Windows, and puts the process to the background on Linux. As I discover to my cost every time I switch between the two.

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.
