    <p>If the user input is always numbers separeted by spaces and then at the end is an enter (newline). Then you can use the following code</p> <pre><code>#include &lt;stdio.h&gt; #include &lt;stdlib.h&gt; int main(int argc, char *argv[]) { int input; char c; while (scanf(" %d%c", &amp;input, &amp;c) == 2 ) { printf("number is %d\n", input); if ( c == '\n') break; } } </code></pre> <hr> <p>If the use want to communicate the number of input as argument</p> <pre><code>int main(int argc, char *argv[]) { int number_of_input = atoi(argv[1]); int input, i; for (i=0; i&lt;number_of_input; i++) { scanf(" %d", &amp;input); } } </code></pre> <p>and when you call you program. you call it in this way:</p> <pre><code>$ myprogram 5 </code></pre> <p>and 5 here is the number of the integer that you can input</p> <ul> <li><code>myprogram</code> will be saved in <code>argv[0]</code></li> <li><code>5</code> will be saved in <code>argv[1]</code></li> </ul> <p><code>myprogram</code> and <code>5</code> are saved as sting in the <code>argv[]</code> array. <code>atoi(argv[1])</code> will convert the <code>"5"</code> as string to <code>5</code> as integer</p> <hr> <p>you can make the user enter an infinite integer input in this way too:</p> <pre><code>int main(int argc, char *argv[]) { int input, i; while (1) { scanf(" %d", &amp;input); } } </code></pre> <p>And you can give the user a way to stop this infinite loop:</p> <pre><code>int main(int argc, char *argv[]) { int input; while (scanf(" %d", &amp;input) != EOF) { //.... } } </code></pre> <p>here you can stop the infinite loop with</p> <p>EOF = <kbd>CTRL</kbd> + <kbd>D</kbd> (for Linux)</p> <p>EOF = <kbd>CTRL</kbd> + <kbd>Z</kbd> (for Windows)</p>

    2. COsee my question. i dnt want program to ask users how many nos. will he enter. I want to allow users to enter as many nos. they want. But I dont know how many nos. the user will enter, so how can I make scanf() type specifiers to accept any no. of numbers?

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.
