title: File I/O word count program in C
body: <p>I know there are several asks already regarding this topic, but it seemed like those were either not completely answered or hard to apply to my code, so I apologize if this is a repeat.
  I am having trouble with the below function in an overall I/O program that also does word and line count (those work). char* filename is pulled from the command line. In this example it is pulling from a txt file with lorum ipsum. (69 words) In theory the below function should read from filename and write it to an array. Then read that array and checks if the current character is a space ' ' and the next character is not. It currently returns 0 regardless.</p>
  
  <pre><code>int wordcount(char* filename) {
  int wc=0,i=0,z=0;
  char w, test[1000];
  FILE *fp;
  fp = fopen(filename, "r");
          while (feof(fp) == 0) {
                  fscanf(fp, "%c", &amp;test[i]);
                          i++;
          }
          while (z&gt;i-1) {
                  if (test[z] = ' ' &amp;&amp; test[z+1] != ' ' ) {
  
                  wc++;z++;
          }
          }
  return wc;
  }
  </code></pre>
  
  <p>NOTES: i know it's super inefficient to declare a 1000 char array, but I wasn't sure how else to do it. If  you have any improvements or other methods to accomplish this, it would be greatly appreciated if you shared. Also, i'm aware that this currently ignores others types of whitespace, but I am just testing this first and will expand after.</p>
  
  <p>Thanks for any assistance.</p>
