title: How many processes, with fork functions?
body: <p>How many proccesses are created with these fork functions?</p>
  
  <pre><code>int main(){
      c2=0;
      c1=fork();
      if(c1==0)
         c2=fork();
      fork();
      if(c2&gt;0)
      fork();
  }
  </code></pre>
  
  <p>In this site,I have seen before questions related fork functions but this one is different. Here we have c1, c2 what does these variables mean?</p>
