title: Error in string initialisation
body: <p>Here I was trying out the following thing in my code and got the following <code>error---"prog.c:10:8: error: incompatible types when assigning to type ‘char[100]’ from type ‘char *’"</code>. Please help and tell me how can I modify my initialisation which is <code>char str[100]</code> to get the right answer</p>
  
  <pre><code>#include &lt;stdio.h&gt;
  #include &lt;stdlib.h&gt; 
  
  int main()
  {
  
    char str[100];
  
  
    str = "a";
    str = str + 1;
    str = "b";
    str = str + 1;
    str = "c";
    str = str + 1;
  
    printf("%s", str - 2);
    return 0;    
  }
  </code></pre>
