title: Nothing showing up C beginner
body: <p>I'm following along with a book on C to learn it and I am writing all the code in the book to follow along, the latest one to do with arrays is supposed to say how many white spaces, tabs etc. There are but when I execute it, nothing shows up, it's just blank, as in I can type something then press enter and nothing happens, is it supposed to tell me how many of each thing there is? </p>
  
  <p>I am too new to understand if this program is actually supposed to output anything so I thought I would post it on here and get an opinion, it compiles and runs fine, no errors, but the book sort of refers to it outputting stuff, but nothing happens when I'm running it and typing stuff in, can just keep typing stuff forever. </p>
  
  <p>Here is the code</p>
  
  <pre><code> #include &lt;stdio.h&gt;
  
   int main()
   {
      int c, i, nwhite, nother;
      int ndigit[10];
      nwhite = nother = 0;
      for (i = 0; i &lt; 10; ++i)
      ndigit[i] = 0;
      while ((c = getchar()) != EOF)
      if (c &gt;= '0' &amp;&amp; c &lt;= '9')
        ++ndigit[c-'0'];
      else if (c == ' ' || c == '\n' || c == '\t')
        ++nwhite;
      else
      ++nother;
      printf("digits =");
      for (i = 0; i &lt; 10; ++i)
      printf(" %d", ndigit[1]);
      printf(", white space = %d, other = %d\n", nwhite, nother);
   }
  </code></pre>
