title: converting decimal to 32 bit binary
body: <p>Hi I have been giving an assignment for my programming in C class and a question im stuck on is this. 
  "Prompts the user to enter a valid integer between 0 and
  2147483647 inclusive, and then displays the converted
  value as a 32-bit binary number with 1 space separating
  each 8-bits in the binary value. If an invalid number
  is entered (i.e &lt; 0 or > 2147483647)"
  it wants me to output the binary in 32 bit format such as 00000000 00000000 00000000 00011111 =31 with all of the 0's and spacing between each set of 8 and I am stuck. </p>
  
  <pre><code> printf("enter a valid integer between 0 and 2147483647\n");
                   scanf("%d",&amp;decimal);
                   fflush(stdin);
                   if (decimal&gt;0||decimal&lt;2147483647)
                     {while (decimal!=0)
                     {
                            remainder = decimal%2;
                            binary=(remainder*place)+binary;
                            decimal=decimal/2;
                            place=place*10;}
                     printf("%d",binary);}
  </code></pre>
  
  <p>this kinda works until the input is over 1000 then its gets messed up. unsure why as well.</p>
