title: Printing file name of with a string
body: <p>Goal: is to print the name of every .c program in a directory specified by first argument that contains some word.</p>
  
  <p>My idea was:</p>
  
  <pre><code>word = "word"
  for file in specifiedDirectory with c file extension
  do 
  if grep -w $word $file ; then
  echo $file
  fi
  done
  </code></pre>
