<P>hello Scone,&nbsp;if your x is gonna be smaller then 100, then your output will be exactly 20 values.. so why would you want to pause it anyways?&nbsp;&nbsp;work on your&nbsp;formatting, its very poor :)&nbsp;&nbsp;  i tried it with x being 200 and it worked... here is the program: </P>
<P>#include &lt;iostream&gt;<BR>#include &lt;stdlib.h&gt;</P>
<P><BR>int fPrintX(unsigned x, int&amp; y)<BR>{<BR>&nbsp; cout &lt;&lt; "x: " &lt;&lt;&nbsp; x &lt;&lt; " x^2: " &lt;&lt; x*x &lt;&lt; endl;<BR>&nbsp; y++;<BR>&nbsp; if (y == 20)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//&nbsp;&nbsp; change the 20 with any number you want to pause it to<BR>&nbsp; {<BR>&nbsp;&nbsp;&nbsp; cout &lt;&lt; x &lt;&lt; " is the " &lt;&lt; y &lt;&lt; "th number\n";<BR>&nbsp;&nbsp;&nbsp; system("PAUSE");<BR>&nbsp; }<BR>} </P>
<P>int main() <BR>{ <BR>&nbsp; unsigned x;<BR>&nbsp; int y;<BR>&nbsp; x = y = 0;</P>
<P>&nbsp; cout &lt;&lt; "This program will search all numbers smaller than 100 that" &lt;&lt; endl;<BR>&nbsp; cout &lt;&lt; "contain the number 2, and will also calculate the square." &lt;&lt;endl;</P>
<P>&nbsp; while (x&lt;=200)<BR>&nbsp; {<BR>&nbsp;&nbsp;&nbsp; if (x%10==2)<BR>&nbsp;&nbsp;&nbsp; {<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; fPrintX(x, y);<BR>&nbsp;&nbsp;&nbsp; }<BR>&nbsp;&nbsp;&nbsp; else if (x/10==2)<BR>&nbsp;&nbsp;&nbsp; {<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; fPrintX(x, y);<BR>&nbsp;&nbsp;&nbsp; }<BR>&nbsp;&nbsp;&nbsp; x++;<BR>&nbsp; }&nbsp; </P>
<P>&nbsp;&nbsp;system("PAUSE");<BR>&nbsp; return 0;<BR>}<BR><BR></P>
<P>email me back.. if you want more explanation of this program..</P>
<P>good luck!</P>

<DIV></DIV>&gt;Date: Thu, 21 Dec 2000 15:21:41 +0100 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Hello, 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;I'm a beginning C++ programmer and I have made a program that 
<DIV></DIV>&gt;calculates all numbers smaller than 100 that contain a 2. 
<DIV></DIV>&gt;It seems to work, but I would like to be able to pause the output 
<DIV></DIV>&gt;when I have got e.g. 20 numbers, and when I press enter the program 
<DIV></DIV>&gt;should continue. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;So far I have this: 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;#include <IOSTREAM>
<DIV></DIV>&gt; 
<DIV></DIV>&gt;int fPrintX(unsigned x) 
<DIV></DIV>&gt;{ cout &lt;&lt; x &lt;&lt; endl &lt;&lt; x*x &lt;&lt; endl; 
<DIV></DIV>&gt; y++; 
<DIV></DIV>&gt;} 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;int main() 
<DIV></DIV>&gt;{ 
<DIV></DIV>&gt; unsigned x, y; 
<DIV></DIV>&gt; y=0; 
<DIV></DIV>&gt; cout &lt;&lt; "This program will search all numbers smaller than 100 
<DIV></DIV>&gt;that" &lt;&lt; 
<DIV></DIV>&gt;endl; 
<DIV></DIV>&gt; cout &lt;&lt; "contain the number 2, and will also calculate the 
<DIV></DIV>&gt;square." &lt;&lt; 
<DIV></DIV>&gt;endl; 
<DIV></DIV>&gt; x=0; 
<DIV></DIV>&gt; while (x&lt;=100) 
<DIV></DIV>&gt; { if (x%10==2) 
<DIV></DIV>&gt; { fPrintX(x); 
<DIV></DIV>&gt; } 
<DIV></DIV>&gt; else if (x/10==2) 
<DIV></DIV>&gt; { fPrintX(x); 
<DIV></DIV>&gt; } 
<DIV></DIV>&gt; if (y==20) 
<DIV></DIV>&gt; { //here I would like the program to pause 
<DIV></DIV>&gt; } 
<DIV></DIV>&gt; x++; 
<DIV></DIV>&gt; } 
<DIV></DIV>&gt; cin &gt;&gt; x; 
<DIV></DIV>&gt; return 0; 
<DIV></DIV>&gt;} 
<DIV></DIV>&gt; 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Thanks!
